My truck 67 f100, 460, worked over iron heads, mild cam, dual plane with cheap holley 750 vac secondaries, tight street converter, 9:1 compression, spins to 6k.

My buddy...68 f100, 427, same wheelbase and trans, bigger converter, nice quickfuel 780 carb, worked over iron heads (no valve job though), dual plane, bigger cam than mine, 12:1 compression, Spins to 7k same gearing as me.

I ran over a second faster than him on a base tune, with major axle wrap, crappy 1-2 shift and letting off He rode in it and agrees mine pulls waay harder than his. And that is because, I have a 460, a truck engine. It has a longer stroke, so I had more torque than him by a lot, his 427 is meant to rev high and make horsepower. Mine is meant to do work, which is great for my heavy azz truck.

Not saying the 427 should determine how all FE's are, as there is the 390 truck engine as well. I've tuned one of those and a 360 as well. Someone correct me if I have overstepped or misspoken, I'd rather learn than go on with the incorrect logic. Just my .02, other guys here have actually built both engines, I have not. Only built a 460, and tuned FE's.

Justin,

I'm thinkin your buddy has a problem with his combination... Tell him I will trade my pump gas 390 truck engine for his race gas 427 so the two of you can go have a close race..... Unless his truck is 4x4 there has to be something up with his combo. I ran a 390 with unported heads and shelf grind comp cam and it went 8.0's/12.7's at the track in my truck with a TCI street fighter converter, 3.70 gears, drag radials, foot braking at 3900lbs we did have really good air that day but still. I feel bad for your buddy and his 427 if that is actually what it is. Can't go off the casting numbers on the block ya know. Anyway I'll go back into my cave where everybody knows me lol. Boat anchors be damned.... I'll still run one.. cause I can..
