[QUOTE="swampratt, post: 4214089, member: 15054"] I think that heavy guts 4L80E and the 2.48 low gear in it is killing the 60 and the large cam and stockish compression. 3.73 gears do not help matters as this thing needs a 4.56 Cam its most likely ground on a 113LSA. If the 4.7 had the lower first gear in the trans 3.059 in the 4L60E I can see a better 60. My 57 4 door at almost the same weight as this truck pulled 1.7 60 foot and my timing had retarded on me to 28 total vs the 38 total it needed. Should have went 1.6. And I am down 100hp and 100 torque at the wheels vs this truck. All in the combo. I had built 1 engine for a 220" dragster with a powerglide years ago AFR head sbc 355" and used a Freakshow converter, I was not too impressed. No idea how one would work for a 4L80 though. [/QUOTE]
