Question for all. as anyone on this forum actually built an LS engine, well i have built 4 of them ground up. One 5.3 two 6.0 one Ls 7 all except the ls7 with one or another with some sort of aftermarket head and port work. All had jesels except the 5.3 which had comp stud setup. All ran stand alone efi ( big money medioker output for $ spent ) but all left happy but i wasn't. The best one made 545hp 520tq 6700 rev hp and p 5400tq at flywheel. The ls7 was an 11000 engine in parts with no labor involved. In contrast 2 months ago i built a 418 / 340 block w2 headed hughes solid flat 10.5 comp MOPAR at just over 7000 parts cost and made 560hp 550tq at rear wheels!!!!! OH and at 6400hp and 4800tq TOTAL BAD ASS relative cheap. I am a die hard MOPAR freak but sometimes you need to know your enemy to know how defeat them.
