I have a 1991 302 engine it has a luniti roller cam, its bored .030, has a Edelbrock Victor Jr. high rise intake with a 650 holley 4 barrel carb., flat top pistons, ported and polished 351W heads, it has been all redone. I was wanting to know about how much horsepower do any of you think it has i am hoping more than 350 horses. but tell me if you might know. thanks
ya i say thats about right...may fall short though due to the fact that your lacking the cubes!!!
whats your compression ratio? 10:1?
i think i am running about 10 to 1 compression so you think about 400 horses
at what rpm?
not sure how much power do you think it has
gee i think the 302 will be squeaking to get 350 hp out of it without any juice. 1.1 hp per cubic inch is a heck of a strong steet engine = 330 hp
should be someone out there that has dealt with the 302 in a buildup and would have a good idea
Here's a torque chart from Edelbrock, 302 with Power Package...

is this a H.O. 302 or a standard output? what's your camshaft?
Hey Jon, around here there is a company with a portable chassis dyno that shows up at a lot of the car shows. You might want to check around locally to see if there is anyone in your area doing the same thing. It sure has shown the truth on a lot of alleged big horsepower stuff around here!!!
Wish they'd come around here. I bet they'd put a quelsh on that dude's Monte SS with a 383 that puts out "700 hp"
LOL, there ya go 'bird. Just recently we had a "750 horse big block chebbie" net a whopping 288 horse at the rear wheels!!! The first few shows they are at in the spring is always a long line up of folks to see how they did on their winter builds. Most of the my engine has 600 hp talk is follwed by a quick put up or shut up now !!!!
PS, don't know about where you live, but here locally it always seems the big horse claimers never really want to go out on the bypass and "verify" all that horsepower.....Lots of excuses why they can't, but never a good reason.....LOL
I think because they have 4.11's or higher and can do a burn out a mile long they think they have a lot more than they do. I heard his monte was only good for stop light to stop light that out on the road it didn't have a top end.
Same thing at the track.
Seems the track magically turns 12 second cars into 14 second cars. lol
What is the 302 going into?
My 302 package puts out 289 rwhp and 295 rwtq on a dyno jet. those are just numbers and the only way to tell is to take it to the track which I should do soon. It takes a lot to get a 302 to put out 350rwhp. My combo is 302, AFR 165 58 cc chambers,BG 650 dp, MSD, air gap intake (knock off profeesionsl products) and the other bolt ons. 350 flywheel hp you should do. I like to tune on the dyno and see what it will do on the track. Let everyone know what it does. Go to a dyno with a wideband sensor. Its the best money you will ever spend
Good luck

Dennis, that is some very good horsepower for a 302!!!! A few years back, thought we had a friends drag motor all dialed in, played with jets, timing, and plugs on the dyno. Results were a net gain of 27 horsepower!!! Heck of a good payback for a couple of hours and 3 pulls on the chassis dyno. Have tried to do everything I build on the dyno since then, results have always been in the plus 15 to 30 horsepower gain.......
hey Dave,
Your preaching to the choir. My car ran a dismal 9.0 in the 1/8 mile and only put out 200 rwhp when I first dynoed it. I had all the go fast parts but I could'nt tune the thing. A lot of reseach and reading and two trips to the dyno I'm happy. I'm going to the track in two weeks and think it might run better that 9.0 at 82 mph.
later dennis
Just wish they weren't so dang expensive, would love to have one!!! The closest one I have access to is about 200 miles away, other than the portable that comes around to some of the car shows. At the shows it's usually so busy, you're lucky to get more than 2 pulls on it in an afternoon. Even the 200 mile trip is worthwhile, like I said in another post, I've spent a heck of a lot more to get a heck of a lot less in improvements !!!!!!!
Upgrades LLC (Huntingtonstreets.com) is 6 mile from my house and great guy. Lots of rice there but good guys. they just do the pulls you do the tuning. they even post the dyno's. I'd like to see what his combo does because I have a gt40 head motor I'm wondering about.
i am going to run the engine in a 1966 mustang gt350 clone its my first car i turned 16 in dec. and i am running about 372 horsepower i found out the car is very fast for a 16 year old and i have fun with it. thanks for all the replys
I know I am late on this thread but I have been trying to do some reading on Ford motors and the 302 and have found some pretty good info. I was wondering, when it goes for rebuild time on my 77 LTD 302, would it be worth it to put a 347 stroker kit in it or just save up more and buy a 351? I plan to put an intake manifold on it from Edelbrock, a carb, new water pump, new fuel pump, etc all from Edelbrock but if I can build a nice powerful street motor from a 351 for cheaper then I may hold off on all this and do that... 347 and 351 isn't too much of a difference too so that is why I am wondering? :?
Thanks!
Almost forgot to add, I will be putting a whole new ignition system like MSD distributor and box, etc on it and the carb is a must because it's old and I am getting no vacuume advance out of the carb side...
the difference to a 347 and a 351 is big, the 347 is higher compression, and lighter, its the same thing as a 302, but different cracnk, rods and pistons... its a full performance engine, the 351 to build up costs a lot a more too, if you start looking manifolds, and such are more pricey for 351s, most of it is interchangeable with other SBF engines, but the stuff that isn't costs a lot more ussually.... depending what the engine goes in and what your main driving use is will depend which motor you should build.... if you want i'll try hunting down an article from JBA that went step by step to build a 500HP 302 for about $500.... the article was written with machining considered free though...
My 79 'Tang with a warmed-over '69 Hi-po 351W putting out maybe 350 hp has never had any problem with "400HP" 302's getting by it. You can't beat...well, you know. The only dyno that counts is long and black and two lanes wide.
