What are your opinions on Heads, Cam, and intake for my application utilizing technology that will be available by May of 2006?

I've searched around but most info is for 402s and 408s.

 

WHO did the re-sleeve
I want to have a ls2 427 done
I believe I would go with ETP HEADS 240'S for the street and weekend track car .
I would also have ED Curtis design the cam.

I concur.
(Mostly ignoring the street aspect and going with the road racing focus): Cam should be a solid roller. Anyone running over 0.700" intake lift yet? My Dynomation work says ~ 0.620" is as much as is needed on the exhaust. Intake just has to be the Harrop IR system! Believe it or not, this thing could make 800 HP with a semi-streetable cam. (The IR vastly improves the low RPM operation)
Oh, yes: it needs 2-1/8" to 2-1/4" stepped headers with custom Burns collectors. Who's going to step up to shoehorning in this pipe size?

 

The BEST would be our CNC ported LS6 2.100 heads that come with lightweight valves.

 

If you're looking for a resleeved 427 LS2 case I have 10 being made right now. They include our main caps installed with ARP main studs.

 

Who's rotating assembly will these blocks be fitted with (USA)
I might be giving you a call .

We have premium components in stock to build you a rotating assembly.

 

Your best choice would ETP's new LS7 style heads with an LS7 intake... it's basically a budget C5R setup! Look at the recent C6Z06 dyno numbers... 540RWHP with a mild cam and no tuning...

 

Katech, how much are these re-sleeved 427 LS2 blocks going to run?

 

Contact Jason at Katech
He is open and honest

How about some LS7 heads and intake? Sounds like you are doing the same thing as me... NA 427 for the street. I plan on going with the Warhawk LS7X heads and GM LS7 intake manifold with a cam in the 25x/25x range, if not 260's with around .650" lift. The heads won't be avaliable until late spring 2006.

 

$4,200 with Katech main caps and ARP studs installed.

 

Well I'm sure they are nice but I guess I will have to settle for the LS2 416ci motor that I was planning on building. I will only have about $4500 in the complete shortblock...unless that tasty L92 block comes available, then we're talkin' 427ci again...w/no sleeves. I know that resleeved blocks are expensive in general but it is a shame that it can't be done alot cheaper.
