I am trying to figure out what I am going to put into my mustang, i am going full carb. non-emission, and I want cast iron block and heads, but this seems way low, is there a reason for this? Like is it the cam they put in, or is it the heads? etc...

Are you sure that is a HO motor? You really want a 85 (210hp) or a 84 (180ish) maybe 83's are up there but beyond that you are looking at all pretty
low numbers. Unless your talking Boss 302's but I know zero on them. I do not think the 76 is HO.

well they did call the 76 302 an HO [ see mustang king cobra's hoods']

yes only 140hp. first year for the 5.0 L ho in stang- :flag:
that's what started it all....

What's this going in ? year of Stang- 79-86 - 87-93 ?

you can find good 5.0 HO motors from 87-92's cheap now days-
just use your Carb setup on the top end, no problem.

Hmmm, I thought that newer 302's (87-93) the head was angled differently so you couldnt use the old school intake manifold and carb.

Thats not true at all. You can get an intake off a 1968 302 and it will fit just fine on an 87, 93, or even 2001 5.0. All the "normal" production 289s and 302s can use the same intake. I say "normal" because the Boss 302 had Cleveland heads and required a Boss-specific intake. The early '60s 221 and 260 I believe had much smaller chambers, valves, and ports.
 
Hmm, well, that is an awesome thing to hear, i thought i was going to be stuck with the older 70's stock 302's to bolt my carb and what not onto, and it scared me because they hit such low horsepower marks... What is the stock horsepower/tourque for 87-93? I hope alot better than 140HP from 76.. although it had 270 pounds of tourque...


Thank you for all your help, this is helping me out big time.

86 -5.0's use flat top pistons 200hp. [u don't want]

87-92 5.0 are rated at 225hp. !
also could use a 93-5.0... it just uses a weaker piston..

-call around to the junk yards, should fine a 5.0- 87-92 for $200 -$550
with less then 80k miles

good luck ! :flag:
 
you can put a better cam and the some E7's and you could probably make about the same as the efi 5.0. the mustang 2 was really down on power because of emissions. i have a 76 mustang with a 4 spd. the heads and cam sucked on those. put an intake,headers,cam and nice 600 carb and you can have some fun.
