5.7 L Hemi, ZF 8HP70 Swap
The price he'll pay for that new hemi will be about the same as the LS3, and that LS3 powered mopar will destroy the hemi
Its not an insult at all. Its a simple matter of fact. From the factory, a new hemi will yeild some pretty underwhelming results for what you're gonna pay.
Ok. Fact check time.
LS3 crate engine 19301326: 430 hp - $6361
LS3 crate engine 19301358: 480 hp (GM Hot Cam) - $6787 (or $8078 with computer and harness)
LS3 crate with engine, tranny, wiring and computer CPSL34L65E: 430 hp - $11,137
LS3 crate engine on ebay: $6650 obo
6.4 hemi crate engine ebay: $7500 obo - 470 hp, 470 ft lb
6.1 hemi used ebay: $5950 ($4000 is more in line with market) - 425 hp, 425 ft lb
LS3 = 6.1 hemi (performance)
They're almost identical in performance with and without a cam swap. Both have hypereutectic pistons. Both have powdered metal rods.
An LS3 powered mopar will NOT 'destroy' a hemi in performance. If anything, it would be a good match-up.
