I was just wondering if the AMC 304 or Ford 302 was the better motor since both are in the 5 liter category. My friend thinks god blessed henry ford and all the subsequent vehicles his company has ever produced so I just wanted to end the arguement once and for all..
"To go off-road or not to go off-road?"
Now thats a stupid question!
I've built several 302's( both winsor and boss) and a couple 304's. If I had tranny and transfer parts for both
I would go with the 302. The 304 can be built into a good runner. The problem I"ve seen with every 304 I took
apart is the bridge for the rockers have been broken and they tend to wear there.
I don't know anything about the 304. But I think I would lean toward the factory AMC set-up. I love the power and performance of my 302. But I had a lot of head scratching and doodling on napkins to get it to work. I would think that a re-built 304 with a mild cam upgrade would be a lot easier. And with the factory set-up, you'd be able to buy a lot of your parts "off the shelf".
But half the fun is building it the way you want it, right?
The 304 is easier to put in a Jeep, being stock and all, but you asked which motor is better. 302, no questions. Stonger, easier and cheaper to find parts for, fuel injection is easy to get, better lubrication system, thicker cylinder walls, better valve train, the list goes on and on.
'74 CJ-5, 258, NP435, D44 w/LockRite
(OK, well the np435 is in the garage next to the Jeep)
WOW!! You guys are making me feel much better about my 302. I grew up on Fords, and this was just a natural step. I was always tickled with the way my jeep performed. But I assumed that the 304 was pretty compatible.
I would go with the 302 for sure. You can find mustang 5.0s for under a grand with everything. That is a great motor and has after market everything....
Anyone done anything with a Ford 4.6? This is the new GT motor and is used in Expeditions, Mustangs, F150s. Does the new 4.6 put out more HP/Torque than the mustang 5.0 HO engines? I know the new suburbans come with a 5.3 compared to the 5.7 (I know, you really can't call a Chevy 350 a 5.7 can you?). Plus, the newer ones have more power...
I've seen some fairly new complete 4.6 ford engines for sale for about $1500.
