Sounds great! Why not a 383. I think you will have less issues with a 383. IMO the extra 13 cubic inches isnt worth it. PM Pete K. He will fill you in. I wanted to go 396 as well, but after talking to a few guys, 383 is a better choice.

Yup, to many issues with the block, having to fill it with block fill and all that fun stuff.

My 396 runs Callies Stealth Crank, Lunati Pro Mod Rods, and SRP pistons. The clearances with the rods really helped with clerancing of the block. I am no machinist, but have been told that is the only area of concern with the block, and the Lunatis help.
Bigger is Better, and 396 just sounds right.
But, I have a 396 and am BIASED
Heres the block. I dont know if it helps.

Hi all
yes, i have a 396 already, with 210cc AFR heads, 234/238 288/292 cam...
the car runs not bad, but the cam isn´t as streetable as i want to have it...want more bottom torque, also, when i swap to the XFI 467 cam, i need behive springs, so i need other valves to get the correct installed height, aso....
so, i will try to get it really right this time with a new combo, and i hope it will be more street friendly, and i know all parts work together like they should
thank you

For me, the jury's still out on the Beehives. From reading posts on other Forums, seems there has been a SECOND batch of Beehives that are breaking.
Rather than run the risk, I opted for Crane Dual Springs that came in a kit with springs, retainers, locks and shims. I also opted for cups to keep them from dancing around against the aluminum.

I visit so many different forums it's hard for me to recall what I saw where. If I come across any, I'll let you know and post them here.

Here are a few batch numbers I've come up with: 49826, 49253, 49045and there are many others.
The Beehives installed on the stock factory Hemi's are experiencing a high failure rate too.
Here's a link with a LOT of posts and PICTURES of Beehive failures. One of the guys on the Forums is compling a listing of batch numbers to post.

Also, if you read through the posts, you'll find a listing and links to many other Forums where guys are posting about having the SAME failures.
Hope this helps.

I'm running the same cam and I went with Crane Duals; kit #CRN-10308-1, which may be a SummitRacing part number. I set the springs a 1.800
You can go to Crane's site and find the specs on just the springs if you want to read-up on them.

Actually I believe that one from AFR is stronger than mine. Look at the spring rate: 391 Vs 428; also those are 1.27 OD and mine are 1.4x. Those AFRs are 155@1.810 while mine check out at 130@1.850
I'm reluctant to get into making a spring recommendation but I know from research that the 467 calls for a 26986 BEEHIVE which is set up at:
123 @ 1.750" and 280 spring rate
I thought I was pushing it with a rate of 391. Best I can do is recommend you stay close to what Comp says you should run. Give 'em a call and see what they have OTHER than the BEEHIVE, that's close to what the 467 calls for.
For some reason, they'e really PUSHING the Beehive springs. Probably has to do with some long term contract committment with the winder.

The springs on my car are PSI. PSI is the real deal in circle track racing. Comp used to use PSI as the prime vendor for their BeeHive springs but went cheap. Like the R lifter.
Things seen to be going full circle. The cheap venders (imports) as cheap and attractive as they seem to be, don't have 100 years of experience in the automotive business.
Shame on Comp!!

The Beehives were outsorced in mid to late 06. I have bought mine in early 05. I should be ok. And my Comp R's are supposedly questionable. I check them too.
Sorry to have gone a different route on your thread corvette 90
But, Think about calling a engine builder that rarely ever has problems, LPE (Lingenfelter) and see what they recommend for your cam, springs build etc. They have scarry fast cars that are very decieving, as they are sometimes very quiet for the power they make.
