I have a 351 Cleveland in a 79 F 100 Custom w/ 33 inch tires, 5 Star Prime Spun Aluminum wheels and a 6 inch Rancho Suspension Lift. I Rebuilt the engine last weekend. I ended up blowing the number 7 piston. I have no idea how it happened, sloppy cam timing due to timing chain, over Rev or what I don't know. But I was just wondering how much horsepower you guys would think a stock 351 C 2V would have with a 4bbl manifold with a 750 double pumper carb on it. My friends figure right now it's pumping out about 330 hp so add another 30-50 hp?

I think without knowing more about the motor it's impossible to tell how much it's really putting out. I will say that 330 hp out of a "stock" 351C 2V is pretty optimistic and 360-380 is probably not realistic at all. 1 hp/CID is considered "hi-performance" and very, very few factory motors ever came close. I believe the highest rated factory Cleveland 2V that came out was 235 hp so even being extremely generous with the "30-50" number from adding a 4V you're still way under even the 330 number.

 

whats the 351c out of?

1985 F-150/351Ho/4wd/6inch with 33's
1979 f-250 429/4spd/

on a quiet night your can hear a chevy (lol,you can watch a dodge) rusting away

 

Just a little more information. The only 351C that was ever rated at 330 hp from the factory was the Boss 351 which is basically just a hopped up 351C 4V. The highest rated 351C 2V from the factory was 250 bhp GROSS not net.

 

I'm pretty sure the engine is out of a '72 Mustang or Gran Torino

Stock 302's pump out an easy 235 hp, both my buddies have mustangs and the guy one who owned the truck before me owns one now. He knows what he's talking about when it comes to Fords and Mustang Power. I want to get it Dyno tested but you have to feel the power and the torque it pumps out. It's insane. My truck weighs 3750 lbs and it almost jumps the front tires off the ground.

Whatever you say. I'm just telling you what the specs were from the factory. Here's the page if you want to look for yourself:

blaxuede,

The only "stock" 302s that ever pumped out 235hp were 1993 5.0 Cobra R engines (and subsequent engines that used those intakes and heads). The most they ever got out of a stock 302 was 240hp in the 1995 SVT Cobra.

Factory spec for a 1972 351C 2V engine is 177hp. Adding a 4V intake/carb to a stock 351C 2V engine will not give you anywhere near 330hp, much less +50hp more. You'd have to add a lot more to that engine to even get close to 300hp. We're talking about a stock engine here, right?

i have one of these motors in my garage right now as a spare, it came from a motego that i used to race ,i always won with it even against big blocks i dont know the horse power but with 373s and auto it was realy fast .it had factory dauls and alum. intake!

 

Right now my truck has 4.55's 4 speed manual. I put a new clutch disk in it while I was rebuilding my engine. All the parts cost me 655$ Canadian to completely rebuild it. I didn't replace the main bearings though it came in the kit but it cost me 100$ so i thought it would take up too much time and I replaced the timing chain and sprockets instead. My fly wheel has a couple heat cracks but nothing major. Should I have replaced my whole clutch assembly? most people say I should have but the disk looked like the only thing that needed replacing. Anyways. I love my 2V , wouldn't change it for anything in the world, you *******s can say it "only" has 235 hp stock, but I KNOW it has more, it's a see for yourself project, I'll get it dynoed, you wait and see.

 

i'm sorry bubba,

YOU"RE WRONG, stock 1988 302 HO's came stock 235 hp

a friend of mine has a 1984 302 gt 350, very rare car, came stock 225 hp. I don't know where you're gettin your facts from

 

OK, and what was it that makes that car so rare...? The engine IS NOT STOCK to put out 235HP! The reason that car is rare is because someone has taken it upon themselves to build a few cars putting out some higher #'s, and in doing so, they have built up this engine.

I love it when guys ask for help then get all pissy cause they don't get the answer they want. Last time I checked my mom & dad were married so I guess I don't qualify as one of the "*******s" even tho' I told him what the factory numbers are. Fine man, dyno it and tell us what the numbers are.

 

I don't know a lot about the 335 series blocks but I do know that they were never real power producers as far as trucks go but can be easily built up if you have the heads from a stock 4bbl motor. The 2bbl heads are pretty restrictive.

 

Also with just a 4bbl mainfold and carburetor I don't see you getting even 300hp with the stock motor.

 

Stock 302s dont pump out 235 hp
