prc h/c package on lq4

what kind of power number would i be looking at with this kit http://texas-speed.com/shop/item.asp...d=832&catid=47 with a Tv2 cam 112lsa on a stock bottom end lq4? what compression ratio? looks like a great set of heads to make my 450rwhp goals with.

not sure those heads will quite give you your goals... I'm and LQ4 build with damn near 450 though... Might wanna take a look at my mine.

how about the 5.3's to get the compression up. http://texas-speed.com/shop/item.asp...d=203&catid=47 this should put me in a better compression ratio range and they flow about the same as the ls6 heads

I'm sure it'll help... but I still doubt you'll hit your 450 goal.

Have you looked at AFR or TFS heads?

what other mods do/will you have?

We've had the LS6 stage 2.5 heads & TSP camshaft make 100rwhp gains before. Do you have a baseline dyno run? The LS6 heads & Torquer 3 or Tsunmai would be a great option.

If you were looking to spend more on aftermarket castings we have some great options for the smaller camber/little bit bigger runner guys. I have PRC 227 heads with 62cc chambers!!

with the t3 cam would it keep me in the 3200 stall range, would it work better with the ls6 or the 5.3 heads, and how about lsa would i need to have it custom ground to work better with the carb?
