Common, The bearing saddles have a groove, that helps offset the alignment issues.

Sounds like a 1g/6bolt head now.The casting number never has ment much to me, these heads get swapped around more than a SBC head.As far as having the 10mm corner exhaust studs, I get requests for that mod on heads, I have done 20 heads or so like that since the 2g E mani is better than the...

ProveIt, you called that one right! Seems the new thing I am seeing a fair amount is the wrong stone used in the cylinder bore. But that is a rant for another day.

I have built both the 4g and domestic V8 heads.What is used for seat widths on a V8 are not the same used on a 4g head.There is also more details to attend to with a 4g than a V8.

Your Killing me!!!I have too many projects now... and you offer this up!!You are a tease!!I am not even worried about the spare engine.... I have about 30 of them!Trade for a ported built 4g head?????? LOLBTW guys, If you think your DSM is a pain to find parts for, and...

Sorry, According to Ted, Engnbldr, he is out of stock on the STD size valves for about 5 weeks.He gave me that little bit of info last week.I honestly have lost count of how many sets of the BC springs I have installed. Not just in the 4g heads but EJ25 and sgte heads.

Make sure the valves have "6T" cast into the valve heads, both intake and exhaust.I just do not trust the parts store valves.Forget the HKS springs, the ones I have tested in the past are just weak. For less money Get the BC1100 this is my goto valve spring for stock and small 272 cam set...

Good deal, that makes the third one I know of on the market.I use the BC6103

So either you have 7 bolt rods in your 6 bolt engine with tons of rod side clearance, or someone modded the small end of 6 bolt rods to fit the 22mm wrist pins so they could hang the 2g/7bolt pistons.All 1g/6 bolts came factory stock 21mm wrist pinsAll 2g/7 bolts and the oddball 1g/7bolt...

I can understand the used H beam rout.But with a 6 bolt H beam the wrist pin is still 21mm, so it would still have to be enlarged to 22mm and have new bushings.But BC has a set of 6 bolt H beam rods with a 22mm wrist pin.I like those and have been using them in several builds.

They look like NPR piston modded by NRP for clips.Not a bad idea, but why hang cast pistons on H beams?Half the price of forged pistons, for half the strength?

I have been installing the BC1100 springs for 6?7? years, easy over 200 sets, I have never had a report back of a valve spring issue.So I say they are good. They work well with the smaller 272 cams, HKS, Comp/FP2, and the BC272Do not use them with the big 272 cams like the Kelfords, and...

If you are going to do valve seals, I would add new valve springs, ARP head studs, and oil port mod 1

The Fel-pro performance line of gaskets are typically a bit thicker, and have a better coating than the stock replacements.It is probably die cut from material that they use for the domestic V8 intake gaskets.They seal very well, and you will cuss if you ever have to remove it. It is like...

I have NIB BC 1100 Valve springs, they work well with the stock retainers. $95 shipped, fees included.I also have the good vition blue valve seals.

Well I found another option for you.If you do not like the price of TT, doubt you will like this one any better.clickYou can pick your build specs as far as C2C, wrist pin dia and rod width.click156mm C2C, 22mm wrist pin, 6 bolt big end.Just what you are wanting.$799 and comes...

The difference in rod thickness between 6 bolt and 7 bolt is about .075 So it would not the best of ideas to bolt a 7 bolt rod on a 6 bolt crank.Are you looking to play with the rod ratio? Want to build a long rod 6 bolt?

The Evo X engine is not the same as the 4G63 engine, the Evo X has a 4B11T.So drop the EVO X swap unless you want to redo and mod the whole front end.The Evo IX has Mivec, so some fab and wire work will be needed to make that work.Now the DSM 7 bolt and Evo 4-9 (?) are close to the DSM 7...

Good deal, sounds like they know what they are doing then.Build on!

.024 top ring gap is not out of line.I would have no issue running a .024/.024 gapI really can not see a blow by issue with that spec.It is also wide enough to keep ring ends from butting, in case of a temporary lean condition.A .024 gap is not going to cause a ring sealing issue.What...

I understand you have Wiseco pistons. I mentioned the CP for a point of referance.There are 2 different schools of thought on ring gaps.The old school method, Where the top ring gap is larger than the 2nd ring, Wiseco, Manley and Mahle provide ring gap factors for this method.Then the new...

Ok gotcha!A bearing location dowel.Darren Up at FFWD has them in ACL coated.No grooves in the bearing tho.

Are you wanting grooved bushings for the small end????By spin pin, do you mean the wrist pin?Or are you wanting a fully grooved rod bearing for the big end? It is not needed on the 4g crank since it is a cross drilled crank and every rod throw has 2 oil points.Now if you are wanting to...

The rings are made from different materials also.IIRC the top is a 1.2mm and the 2nd is 1.5mm.Also .002 on your ring gap will not kill the engine, or cause excessive blowby.It will allow the ring to expand a tad more if you hit a lean condition, and just may save the piston ring...

I have a couple, fresh surface, bolt on ready. Step height is set to .610-.612$85 shipped.

I do not know what brand of engine stand you have. But I do not have any issues swapping from a SBC or SBF to a 4g block.I have 14 engine stands.The 4g Main bolts are the perfect length to mount a 4g block to the stand. On some stands the trans alignment dowels need to be pulled out, If the...

While I was working today, I thought of this thread.Working on 2 7 bolt blocks, and an EVO block.All are getting ARP main studs 207-5401 Torqued to 60 ft/lbs with ARP moly lube.Main housing bore spec 2.4016-2.4024 .0008 is the target for a good bore.DSM block #1 falls into spec...

Check with a guy named Steve (?) at throttlebodies.com clickI have bought a few from him, damn sexy out the box.Check out the bored out 63mm

No, not every block needs align honed with the use of ARP studs, I would say 1 out of 5 needs it.I will install the ARP mans, then check the main bores, if they fall in spec. go on with the build.If it dose not, then align hone.The use of the girdle doesn't mean you need an align hone...

I have a 3 bolt w/ axles.The cover is marked "B17" Vicious LSDIIRC, It came from a bud's 4 bolt swap from his 1g Talon about 6 months ago.I inherited when he moved, about 2 months ago.I also have an EVO chunk also, missing the diff, but the ring and pinion gears are in it.Ill toss that...

99 lbs plus packaging

That is engine building for you, Be as anal as you want to be.Now to go play with a B20....

If you checked a couple and the repaired one was close. bolt it in and go.

I hope Delta did more than grind/polish it down.That section of the journal does have an oil feed to it, so if all Delta did was grind it down the oil clearance will be too large, and rob oil from the other journals up the line.If you have a set of dial calipers, measure it, and compare it...

Can you feel anything with your fingernail? or is it just discolored?I doubt they just ground it down, with as bad a groove you had, your oil clearance would be huge on that journal.

What is the letter on the cam, just behind the #1 cam journal?

No, you will not have to resize the H beam rods, the high to low spec on the housing bore is .0007 no wiggle room there.Who ever gave you that tidbit of info has not resized a set of rods.If you loosen the housing bore, then you will not have proper crush on the rod bearing to hold it...

I forgot about you yesterday, I got you covered tho.Check your cell

I have built 1 head that caps off a 1000hp engine. So I have a good idea what is needed there. None of it is cheap.Now what is in the bottom end, or what turbo, or what supporting mods were/are used. I can not say, except a custom intake with a set up of 2 injectors per cylinder.It was at...

Felpro 9627PT composite about $40 from any of the chain parts stores.If you just want a a cheap HG, I have a pile of them from engine builds I have done and replaced with the felpro.$15 shipped, Use at your own risk.

In my area, it is $100-$125 per side.So unless the head has had extensive work done to it, you would be better off with another core head.

I have only checked a few cams for clearance, mainly after a line hone.I have laid cams in the journals and checked for rock, or warp of the cam towers, Installed cams in bare heads and made sure the cams spin by finger.But I can not recall ever checking a cam with plastagauge.It...

The big thing with any gasket, is a good clean oil free surface and proper torque on the bolts that join the parts.Yes some gaskets are more critical than others, the head gasket being the main one, along with a decent VC, front crank and rear main seals. You can add valve stem seals to that...

I used mostly Engine Tech gaskets, no issues from them, They are not bad priced. But I toss the HG and use a Felpro 9627PTBut I have also used, Evergreen, Erstic, Topline from Ebay on some builds, customer supplied. I still toss the HG from all of them, along with the oil pan gasket, and use...

I only needed one journal on one cam fixed the last time. It was a Kelford in a RB26 build.It ran me about $75 total, shing there, the repair and the return shipping.Best thing to do is call Delta, ask for Jon, and tell him what is going on.clickHe will be able to give you a better idea...

With the oil port mod done, you should have decent flow to the head.From what I measured on about a dozen head, the oil port with head gasket thickness needs to be appox .100 deep to put it around what it was from the factory.

tekic, Did you do the oil mod? Do you know the thickness of your head? What HG did you install?Keep in mind the head is oiled last, so pressure and flow are reduced by the time it makes it to the head. But from reading of the Kiggley HLA regulator, the HLAs need about 15psi.It can take 30...

For the oil leak.... Did you put some sealant on the bottom middle exhaust stud?That stud is the oil one into an oil return and will give a leak. Just a touch of RTV will cure that leak.

My personal preference would be.GSC "shorty" bronze guides. +1mm OS valves (Engnbldr off Ebay will be fine) The GSC 5041 kit, great choice. The Viton Blue seals are a no brainer, and all I use.With the OS valves, make sure they are installed properly are you will not see an air flow...

Thats bad, the cam journal that that came from must be close to junk.The cam can be repaired. Call delta cams, ask for John, tell him I told you to call.He will grind it undersized, then weld it, then grind it back to spec.Cost with shipping should be in the $50-$75He has fixed several...
