Title: 351 vs 302
Post by: im gay as hell on November 28, 2004, 09:25:37 PM
how much horse power does a 351 have and a 302 if both of thses engines go at a race which one will win and does any one have an opinon because i have an 87 tbird 5.0 and i put shorty headers mac h-pipe with out cats and mac cat back system and it sounds might ruff i bought this system for an 87 mustang and it was to short and i did a lot of adapters to make it fit and now the problem is thats its 4 inches away from the ground its to low  but how much horse power does the engine have stock and whats the top speed on some stock t birds out there especially turbo coupe

I would put my money on the 351. Mainly because it is bigger. With duel exhaust your car should hit about 160 hp. the 351's start at 180.
You should be able to hit 140 mph easy. I have hit 132 running like .

Some details on the 351W would be helpful aswell, 2bbl, 4bbl, whats it in, is it original? I seem to remember that the 351W I have out of my 79 econoline was rated at like 120-140, not that amazing

if my brother is bigger than your brother, who would win in a fight?!?! WHOOOO

more information is needed, i could get a single barrel carb, slap it on a 351, some exhaust manifolds with 1.5" exhaust, and be a turd, or you could go full EFI...etc

and why would you even care about top speed? it serves no purpose

My :2c: ....

302 parts are cheaper and easier to get....

The 351 will also add weight (Not sure how much) and not only power.

Let's just assume we're talking about Windsor blocks here.  Not much chance of a cleveland. 

Top speed = teh win!  190mph is the best!

351W: Advantages

Strength: The 351W block is stronger than the production 5.0 by a long shot. Thicker walls and 3-inch main, and 2.311-inch rod journals (versus 2.248/2.123 for the 5.0) are contributing factors.
Taller Deck: The 351W features a deck height of 9.503 inches versus the 5.0’s 8.206 inches.
Rod-to-Stroke Ratio: In stock configuration, the 351 has a better rod-to-stroke

if u took both motors with same basic build up the 351 would make more power and tork over 302 every day of the week and twice on sunday.
But 351 is also 100lbs more too and a tad bit bigger.
