i have about a grand to play with. originaly a was going to do edlebrock preformer heads with a good cam that makes torqe and custom chip to acomidate because of it being speed density. but a stroker sounds good to what do you think. i am still doing the 1.7's as well. and the mass air question came from the fact of having to order a custom chip for the speed density as oposse to the mass air acomidating the upgrades.

The edlebrock heads are good & with a good cam they will work nice . But if you have a budget i would look on craigs list to find some good heads . Gt-40s with 1.94-1.60 valves you should be able to find there are alot of guys parting out there 5.0 stangs Just a thought .. If you go that far you will need a custom chip or tuner for sure & mass air is the way to go .. Even this will be alot more than grand..Lew

Lew and I have "discussed" this before
, but in the big scheme of things there is no such thing as a torquy 302, I say this having compared similarly equipped 5.0 and 5.8 motors in my truck. The 5.0 makes better power at higher rpm and high flow components amplify that, so if you go that way with heads and such just regear the truck to match the new powerband. Lew will tell you his 302 is torquey but it also has 4.56 gears which is a great example of what I'm talking about.

The 302 works good for me but its in a light truck with low gearing . The 302 likes to rev & gets to the power fast . My 302 makes more torque than an HO but will never make the torque of a 351 . So in a heavy truck a 351 is a better choice . Milesmac has a f 250 so a swap to a 351 might be better for him . It takes alot of money to buid a 347 stroker . So everone allways misses my point . The 302 isnt a useless motor like some pepole say they are . In the lighter trucks they work great & i have the truck to prove it . And a 302 isnt a torque monster but to say it doesnt have any is where i disagree . A 351 in a f 250 ext cab 4x4 is going to be about the same as a 302 in a f 150 2wd reg cab . Then theres the 460 !!! Lew

It really just depends on your need. If you need a Farm truck, a 300 might be better for you just because it's easy to work on and realiable, and does get about 1 mpg better. You can gear it to Heaven and keep it on the Farm as a semi tractor.
I think it all depends on your needs but for a half ton truck both the 300 and 302 do great.
And then there's the 460..

I've always thought a 302 has just as much usable torque or more than the 300. I saw an 80's model F-150 with a 302 launch one time. That thing launched so hard it was just plain stupid. I know the guy and I highly doubt he changed out the gear ratio (it was a work truck). He uses it to pull a trailer and he LOVES speed. I really can't see my sloooow truck beating another truck identical to mine with a 302 in a bumper pull off. Who knows, maybe my truck would surprise me. I just can't see it.

No.. the 302 is a panzy motor compared to the 300 in terms of low rpm grunt, it's doesn't really get into similar TQ output until above 3000rpm. And you can't use it's performance in a mustang for comparison, those cars are on average 1000lbs lighter than a pickup so it won't require as much TQ to accelerate. The 5.0 in my truck right now produces more TQ and HP than any stock 5.0HO ever did(350TQ/280HP) but it's a sniffling little wimp compared to the 5.8.. which is the V8 that's similar to the I6 in TQ output.

And I will. 270 is what the 302 was rated from the factory.. and it was at 3000rpm, in '95 the regular 5.8 was 325@2400 and the Lightning made 340ft/lbs. My 5.8 was making 400 ft/lbs at 2000rpm with the cam and longtubes and this is the big difference I'm talking about, the 302 is down around 250 ft/lbs at that rpm. If you compare the numbers at 3500rpm there's only 50 ft/lbs difference, but with the 5.8 I can drive around and haul stuff without ever exceeding 3000rpm, so in the end the 5.8 makes a better truck motor and could potentially deliver better fuel milage. I know I regularly got 13 cty with it and that's better than many 302 trucks on here.

hey guys i really appriceate the input. and my truck is not an ex cab. its a LD staqnderd cab 250. i thing between edlebrock heads a torque cam with 1.7 roller rockers with a custom chip it will preform? anyone dissagree? and better gas millage to boot. more toque the motor makes the easyer the truck moves
with less effort. as long as you can keep your foot out of it.
does the 5.8 intake plenum breath better than a 5.0 plenum? and will it bolt up to the 302 intake?
and whats the red line on my 302
with less effort. as long as you can keep your foot out of it.
