Do it. It will be a real grunt monster and probably drive like stock!

Yeah with XER lobes this cam should make tons of low end above 4500-4800 rpm. It would be a really good daily driver cam if you keep the lift low ( 640ish).

just because the low lift #s aren't as high as other heads,doesn't mean s#*t..don't believe the hype about low lift numbers...at what lift is the piston creating the most pressure differential in the cylinder?

also remember, the exhaust side is without a pipe, where as AFR's are flowed with a 1 7/8's( believe) so the exhaust side should look a tad lower... they also flowed theirs on a larger fixture 4.125(if i recall correctly) instead of the 4.030 that i had mine flowed on... so there are a couple differences there.....

just curious if people think they will make good power.... etc.... if i got a good head on my hands etc..

there's more in that thing once you get it tuned right..

I'd bet with a stock bottom end you could see 500whp with a good cam like the T-Rex!!!

they are NOT TSP heads..
but how much power would a T-Rex make at 3000rpms?
for a true street car,it's not about peak #s..there's a lot better cams out there for a street car..

That's exactly what I was thinking. It would probably be an excellent autocross build.

my previous car was a H/C LS1 Z/28..did all the work myself except the exhaust and gears..learned a little about what makes a good street car,and also found out most people on the 'net are clueless about what really makes these motors work..
and why are you running an LS2 intake?those things stock don't flow as good as an LS6...
