Didn't I read in another post you were using all forged internals w/ 6" rods? your going to want to get some good fasteners or there is no reason to use forged parts. Order some ARP rod/main bolts.

These are the stock specs Rods 45 ft lbs Main cap bolts 75 ft lbs oil pump 65 ft lbs , but if you are using ARP's or another high pro fastener than I would use there specs.

Kinda scary. You can't change from bolts to studs without an align-hone.

Some specifics here would be good - you're asking questions that kinda seem like you haven't done your homework on the build...not trying to be a d*ck, just don't want you to fire up and make expen$ive scrap...

No worries - trying to help here :)

So you're NOT using a windage tray? And the machine work is already done on the block and rods?

And I hate to ask but...you're not REUSING the rod/main bolts, correct?

I'm a little leery of diving in here - you said the bolts were stock, then they were ARP. I'm going to pass as good advice given out of context can cause problems :)

My suggestion is to work with your machine shop on this stuff if you don't have someone local that can help out.

So...here's why I get hinky :) Again, not trying to be contrary - but sometimes questions get asked that demonstrate that the person asking needs more than just the answer they're asking for. So let me try to lay this out in a way that makes sense.

1. If you had machine work done with one type of fastner (bolt or stud), you cannot switch to another without an align-hone.

2. Studs are required to support a windage tray, and there are longer ARP studs to do this.

3. A windage tray is a good idea...but not required.

So we're clear - I ain't an LT1/4 expert by any means. I've built MANY GEN I's but I've learned a lot the hard way on my LT1 383 build.

What are you using as an overhaul reference?

The LT1 has a windage from the factory (vette/Fbody) and Iam not 100% if you can use it with a 383 or + cube build, so if I was you I would just order a ARP kit for a LT1 and be done with it . IF YOU USE ARP USE THEY'RE TORQUE SPECS!!!!!!!!!!

speaking of torque specs. can yall tell me the torque on the head bolts? and also where i can find the sequence of tightiening them?

it is a high compression 355 and i contacted the machine shop that did the work for me and they told me that 99% of the time when switching to a stud you dont nned an align hone so i ordered the studs

So you only wipe a main bearing 1% of the time? :dontknow:

Good luck, man - I got nothing :)
