you act like its a FEAT to get 525hp out of a 280+ cubic inch motor. plain and simple the head flow just ISNT there. bone stock 5.0 heads flow in the 160cfm range on the intake. same with the 2v 4.6 heads. ls1 heads flow around 240cfm stock. with the extra cubes sure its easy to take advantage of the flow, but REALLY? you cant blame it entirely on that. because really its like a 60 cubic inch difference. while its a decent amount, shouldnt the heads/cam N/A numbers be 450 rwhp? more better? again, perhaps if you 4.6 guys push the boundries and find out what these motors like, things like 400whp h/c might not be so unheard of. and PARTS to do it might be CHEAPER. thats my point. ls1 guys are always pushing the boundries. where are you guys at? EXAMPLE - a set of AFR heads USED TO be like what... 3.5 grand? only 2300 now. because things get cheaper with popularity.
why are you guys afraid of compression again?? it seems funny the remarks you guys make about CR.
