Golen 383 - 4 bolt splayed caps, forged SRP Pistons and cylinder surface
I just got a Golen 383 short block out of the crate and have a few questions. Block # is 14093638
1.
These are not looking like splayed caps to me. As I payed $200 for CAT MB-350SS billed splayed caps, I want to know if these are definitely not splayed before I complain.
2.
I payed for Mahle forged pistons with a -16cc dish. I got SRP pistons P/N 138103 which are forged and -16cc, too.
Is the quality and strength of the SRP pistons equal to Mahle?
3.
To my surprise is a little bit rust on the cylinder surfaces. It's not much and I could extensively remove it above the pistons with abrasive cloth and WD40.
The engine was 3 month in the crate so I do not blame Golen for it but I wonder why only the cylinder surfaces are affected and nothing else. Maybe a short block should be sprayed with WD40 for international shipping?
Should I disassemble the block and get it honed or is it not a big risk to let the actual condition as it is?
before
after
And finally 4. ... what is this? I never noticed it before on an L98 engine.

1. - definitely not splayed! those are STOCK GM 4 bolt mains - you got hosed
2. - SRP's are ok strengthwise for what you want to do - they are considered a budget piston however and you should have been charged less for the SRP's as opposed to the mahle
3. - you just winged it with abrasive cloth? normally a hone is used but that's about all the hone is...i think as long as you wipe the cylinders down with a good cleaner first then recoat with oil you should be ok...
4. - that is not a stock L98 block thats for sure. that is a gen 1 with provisions for mechanical fuel pump. you will need to purchase a fuel pump blockoff plate and install - then install your motor as normal

Thanks for the fast answers.
I plan to install a Procharger in the future so do you think the SRP pistons are ok?
I'll check with Golen regarding caps and pistons.
The blockoff plate is not a problem I can make one.

I bought SRP pistons and was kinda bummed to hear my machinist talk so badly about them. Didn't give me any reason other than saying he hates them and would never buy them himself. But they are made by the same company that makes the high end JE pistons though.

LT1, at the very least. They might have modded the block earlier, but I don't think they did. I know my wifes 87 had the block off plate. And since they redid the thing for roller rockers and a 1 piece rear main seal, this would have been a good time to ditch that.

One piece real seal adapter or is it still two piece? Guessing a non roller block, too.
Too much wrong with it to ask for just a credit, make them eat the shipping and build you the right one. That sucks.
If yo ukeep it at least clean it up with a proper hone for those pistons.

Guess what? The piston coating is an ordinary TBC and not Swain Techs Gold Coat what I ordered. That really sucks as I want to install a Procharger and wanted the best coating for it.
I ordered at Golen due to his good reputation. That I got not what I ordered sucks.
Btw, the block # 14093638 is one piece rear seal.
This engine block is used in 1986-99 Gen I heavy-duty applications. It has 4.00" diameter cylinder bores and four-bolt main bearing caps. This block is machined for a one-piece rear crankshaft seal. (Does not include rear seal or adaptor.) These blocks weigh 197 lbs.
Technical Notes: Cylinder wall thickness is the same as current production engines. The lifter valley is machined for hydraulic roller and flat tappets. Crankshafts with two-piece seals can be installed with adapter P/N 10051118. (Block casting P/N 10243880 or 14093638.)

SRP is an off the shelf forged piston but they are pretty decent IMO, I would run them in a hot second with forced induction.
Send this link to Golen and see if they will do something, at least a credit for you to ease the $ pain.
Many many people here (myself included) have recommeded them, this doesnt look good...Mistakes happen though.
Lets see if they step up to the plate and take care of you.

a 623 is a good block and i would imagine that the studded 4 bolt would be as good as a a splayed with bolts. either way that sounds like a bad *** short block..

623? I have a 638 ... I'll go for 8 to 10 psi boost but wanted a block that can handle a 14 psi boost.
Don't get me wrong, everytime I got a question Golen sent an answer within hours. That's excellent, but the caps and the coating are disappointing.
I've sent an e-mail to Golen and will see what he says ...

When I ordered mine, I got billet caps, but not splayed. Chad talked me out of them due to not being able to use a dip stick with the splayed caps. Keep in mind mine is a LT1, but with the billet caps, slp pistons, H-beam rods and forged crank, its supposed to be good for 750hp.

The mains are studded, not bolts. Will some of you stud experts look at the outer studs on the 3 center mains. Nuts are not fully threaded. Don't seem right to me.
