[QUOTE="tt335ci03cobra, post: 12717445, member: 68944"] Also, mrlrd, if you were honestly not referring to anything from the article I posted up then cheers. coincidence maybe. In the article you're referring to, It made 1200hp @26psi (maybe~1050whp?) in that article but did have an off the shelf cam, ported heads, full fast system, gapped rings, flat top pistons, arp head studs, new gaskets etc, throttle body, etc. It did have a stock rotating assembly, unless flat top pistons weren't factory on the 4.8. Cam and heads alone is $600-1000 depending on the route taken and higher if labor is involved. Fast is $$$$ and the throttle body is another $2-300 if my memory is correct. My point was simply that a stock long block/cam/head 4.8-5.3 won't do that. Cam/head porting/fast/accufab, nice twin 76's at 26psi (not china junk) etc all did most of the work. Plus an engine dyno isn't as hard on a motor as a chassis dyno is where components and drivetrain are spun. As impressive as the 4.8 is based on the article [url]http://www.hotrod.com/techarticles/hrdp_1109_stock_gm_ls_engine_big_bang_theory/[/url] I still think its nowhere near as robust a long block as the 4.6-5.4 forged modulars. Why do i bring this obvious sentiment up? You asked what good is a heavier smaller displacement motor? IMO better for boost. Twin 67's on 03's have made 1188whp which is well over 1400hp...
