The only point of that is if you really want to say you have a non production LT4. For less than that price you can have a killer heads and cam combo that will outperform the LT4 conversion.

yea dude...go over to camaroz28.com and look at the numbers some guys are putting down...even though the LT4 heads flow about 30cfm more then the LT1 heads, guys are putting down well over 400ponies...i said down not crank..

i bought my set of LT4 heads on ebay for 1000 bucks fully assembled with bigger valves and HC springs....so that kit is a little overpriced IMO....i bought a used roller cam (224/230 2,000 miles) off camaroz28 for 150 bucks and the 1.5 rockers off there for 125...the EFI intake byitself is 225 bucks..there 1,400 bucks...and itll make 30 more crank ponies then the HC


ohhh and btw dont let there prices (gmpartsdirect) fool you...theyll make up the difference in shipping .....
