351c

[rerun]

hey, first of all sorry for not listening to you guys about the 351, you guys saved me money, that i don't have a lot of, anyway, i was wounder about the 351C or stick with the 289 for now, post what you think...
P.S i REALLY want a big block but he parts are twice as expensive and i can't afford them right now

If money is a real big concern to you, then stick with the 289 you already have. Just curious why you want a Cleveland instead of the Windsor?

[rerun]

well they are physicly bigger, and they makes tons more torque... plus if i can find a 4V they make 380hp stock

Actually, the 351W will make more torque. The 351C features canted valve heads with larger valves than the Windsor, but the larger valves will hurt velocity, and subsequently, torque. The 351C had a reputation for oiling problems due to the overly large oil passages leading to the top end of the engine, and the bottom end isn't as strong as the Windsor engine.

That being said, I'd take a 351C over a 351W anyday just because of the cool-ness factor, but for all out performance, it's a tough call. If you don't have money for aftermarket heads, the Cleveland is the way to go. There has never been a factory 351W engine that has impressed me. As a general rule they had little power, cheap components, and got lousy fuel economy.

On a side note, finding a 351C that is rated at 380hp would be interesting. I don't know of any that were rated that high. The Boss 351 was rated at 330hp, and I'm not sure there were any higher. Most Clevelands were of the 2bbl variety, and while still more powerful than the 351W, they weren't road rockets.

The 289 is still your best bet, IMHO.

thanks, and i have absoltly no money for new heads... and are you sure about the torque thing, i mean i know a 2V wouldn't make as much torque but a 4V might... not sure though so i'm not gonna argue about this one

[rerun]

well thats what someone told me but i read some where that it weas 380 torque, and 300hp....... that sounds more realistic

351C are one of the most expensive motors just cause of thier heads. The 2V heads are cheap but will net you shit for power. Next the 4V heads make good high rpm HP but are a lil weak in torque department. A good set of 4V geads are big$$$$$. Finally we have the best stock made head overall the 2V Aussie heads not as much as 4V but still a lot. These are just your stock Ford heads. Now aftermarket heads are few and far between but you will pay double for Cleveland heads.

Even the 2V Cleveland heads are superior to the Windsor 4V heads. Quite frankly, the 2V heads have larger valves in them than what you can even fit in a 351W. 2.04/1.67. The Aussie 351C 2V made it's power via high compression. The 2V heads you'll run across should be decked or you should run some higher compression pistons on them.

Windsor 4v heads? What are those?

Ok here's the deal on cleveland heads. to start with its getting hard to find a 2v motor let alone a 4v motor. if you were going to build a motor from scratch and had both motors at your disposal I would build the cleveland. they made more power than ANY windsor motor ever thought about in factory form. as said before clevelands have downfalls thought weak oiling system and parts are getting hard to find. and one other thing that noone else mentioned they have long pushrods and if you like to keep them high in the rpm range they bend pushrods. those aussie heads have a smaller chamber and its a different shape to burn fuel without detonation. you can use different pistons but you will have detonation problems above 10.1 as far as 4v heads go dont waste time or money trying to get them not with it. I have a 73 351cj car with the 4v heads on it the car dosnt have much power off the line until you get car about 3500rpm then it pulls good. but if you really really want those heads dont use aut tranny.

I don't want you to take this badly but there are a lot of newbs lately and maybe you don't know but this is like the 5th time this weak by newbs. Stop bringing up old threads!!!! It's kinda annoying.

But welcome and stick around it's nice to have new people in the Mustang Forum.

Clevelands are in a class of their own. They are basicly big-blocks that bolt to the small block bellhousing hence they are small blocks. they will produce monster power at high rpms but like most fords struggle at the low end. 2v heads will help with that and actually out perform 4v heads to a point, depending on how wild you go. The '71 boss mustang had the best 0-60 time of the muscle mustangs (64-73) and was the heavist. We run a 72 351c bored to 357, edel torqer, herbert .550/.575 lift, frg ft pistons, stock bottom end, comp rr, 4v open heads,huge valves (can't remember off hand) 2.25? 1.9? alchy inj ron's flying toilet. 5500st powerglide rearengine at 8.87@153mph all motor. Not bad for a sbf huh? We twist it to 7k. I'd like to see a windsor with same setup run this fast. Can't do it can't flow enough w/o aftmkt heads. I love 351w but the 351c is just more intriguing.
