been a long time.... need some advice on building a low rpm 5.0

BowTie Eater 5 Liter · 11-03-2004, 01:23 AM

hey, been out of the 5.0 thing for quite some time, not back in it quite yet(ill get another when i stop spending cash on this truck), but i need some help with building a 302.

what im looking to build is a low rpm torquer motor for my truck(its a 1984 ford bronco 2, 4x4, 1/2 ton axles(high pinion dana 44 and an 8.8 out of a f150), detroit locker, 5.13 gears, about 6" of lift(rock crawler springs.....) on 36" military tires. it has a 2.8l in it, which works, but i need more power.

i was wondering if a stock 5.0l(87-93) out of a mustang with a edelbrock performer 289 intake and about a 650 off road carb(holley truck avenger) would make a lot of low end power, but still pull decent up top? or would i be better going with a truck motor, and put that carb and intake on it, or even building a motor(need suggestions of parts to use on it, not even sure if the performer 289 would be best, im really rusty on the 302 thing)

thanks a lot

I think a 87-93 mustang motor would be ideal for what you need. Just put a low rpm range intake manifold and an off road carb and the 300ft lbs of torque the 5.0 produces would perform very nicely in your truck IMO.

Yeah, what he said.

Possibly the Torker II intake would be a better choice. Read the specs, see what RPM range you want to be in, but sounds good to me!

Have you ever considered a 4.9L 300 ci straight 6. Excellent torque and power with the lighter weight. And you can beat the piss out of them, especially great for mudding purposes!

ive put 302's through hell, i know they will stand up, but the I6 i believe will be too long to fit in the engine compartment, i believe the 5.0 is an easier swap. plus, i cant live with out that v8 sound

As Jester said, go with the torker II manifold, you won't be sorry. A 600-650 carb is fine. Just make sure you get the right cam! Without the right cam, the power ain't all there. If you're really in for some torque, build a 331. Just my .02.

Hey Kris, how you been? Good call on keeping it fuel injected, you won't have to worry about flooding it on big inclines. It'll give you what you want.

not too bad, how about yourself? i got totally out of the mustang thing for a long time, buddy just bought one, i got the bug again, but i cant afford one right now, this 4x4 thing is really expensive, gonna be about 12000 canadian into it.

looks like youve got a little more than the old 13sec gt last time i saw u run that car at the track.
