I didn't know this page existed so I copy/pasted it from the 351Cleveland.net site at this address: http://351cleveland.wetpaint.com/page/The+Amazing+351C+4V   Here's the copy/paste... Enjoy!

And it is one of the best looking motors around.. ;)

 

Interesting read. I didn't know they ran toe to toe with the 7 liter engines. I am going to look for other documentation on that.

 

I have a 351c-4v. I haven't tried to turn it up to 7200 rpm. I don't think the cam and valve springs would support that but I understand that if I had the right valve train, the bottom end would hold up no problem.

My tach goes to 8000 and no redline. Always wondered about that.

that is one killer artical...loved it!!.... but i wish they would of talked about the banning of the 351 cleveland....i read.... It dominated NHRA Pro Stock Drag Racing -motor was effectively banned from NASCAR for the sin of breathing "too well." <~~ got to love that..motor was just too good..and other car compaines cried about it..lol

I pointed out that tach to my brother once, when he owned a Mazda with a rotary engine. He dared me to rev it that high, and added, "I can run at 8000 rpm all day." Well, neither of us wanted to do that to our engines. I still have the Mustang, and his Mazda is history.

That is a great write up on this motor. I followed a lot of his advice while rebuilding my motor, mostly factory parts .600 lift cam and 7200 rpm were the goal. I shift at 7000 rpms all the time and so far so good. Might try a little more revs this fall

Nice!

 

Hey, still interested in the NOS Super Comp headers I have? I'm ready to sell. 7200 shift points!...I think you qualify as using them to potential. :) Shoot me a PM.

The 351C 4V, whether open or quench chamber headed LOVE the high RPMs, when properly modified. When I was running one, I routinely turned mine to 7500 as I had to in order to get the best out of the motor.

 

Mind you, this was with open chambered heads that had been modified for solid lifters and 12:1 popup pistons. I did all the oiling modifications and Yes, I was able to run with the Big blocks, except for the modified hemis. The only real problem was having to turn those high RPMs. Trust me, that can get scary sometimes.

 

That is why I went to the big blocks. They were (and remain in my opinion) cheaper to build and you don't have to turn those high RPMs to get the job done, especially on the street where TORQUE is king!

 

Believe me, i am not knocking the 351C. I have a couple of them in my garage, both open and quench chamber headed but I am now a confirmed BBF man:)! I will keep the 351C in the event I decide to go back to stock someday.

Sure there is, it's called forced induction.

I've always been a big block fan, but after that I really want to build a cleveland! I've been around 289s n 302s and they were great motors but just (in stock form) didn't have the power n torque for the bigger mustangs.

I've never had a chance to drive a cleveland, my mach came with one but at some point in time it was traded for a 302. Then I built a 532 for it.

Great article and post, anyone got a 4v cleveland for sale? :)

Very interesting read.

I wondered about an 8k tach without a redline.

I've run mine up to about 5k, but was worried to get it any higher than that.

I guess 3500 rpm cruising on the freeway isn't even close to the limit.

 

I have to agree, I have a pretty amazing motor indeed!

Gearge is a great guy and is a very good writter and very detailed in his analysis of the Cleveland.I will be using his advice for my build this winter (I hope) of a new and improved Cleveland.

The Clevelands have no problem with RPM. They love it! Gearge said,Ford engineers took a "race motor" and de-tuned it for the street.

Like Cobra3073 said, I too had the open chamber built motor ,with the shift points at 7500,using preped stock rods,and crank. No issues.That was the most fun engine I ever had !

By the way Gearge is on facebook also.He is always open to questions and helping others. He does not beleive in strocked Clevelands though.He likes them the way they were designed.

Back when I bought my 73 2V, I set out to make it a respectable 1/4 mile pro street contender.

All of my freinds dogged me about the cost vs chevy everthing fits and is cheap. brings back great memories of my #1 Chevy 69 Camero nemisis who tried, tried something else, and tried some more. NEVER BEAT MY FIRST BUILD.

This article is awesome and tells me I've always made the right choice. Wait to you see what I'm building now.

Back in 1972 when I was working at the Ford Dealer, one of the mechanics bought a new Gran Torino Sport with a 351 C, I will never forget my 1st ride in that car...I thought it had a 429 in it....I made him show me the engine ..that thing was very fast !

Fantastic article. I've broken a few valvetrain components but NEVER a bottom end problem on my Cleveland. Tried a set of Holmstrom exhaust port plates years ago and couldn't keep the car straight! These motors smoke any other similar displaced stock motors of their era.

Thanks for bring this up. It is something I tried to explain to some other Mustang enthusiasts about why I did what I did to the top end on my motor by converting it to run a solid lifter cam with .570 lift and not doing any head or oiling mods. I chose a cam that complemented the engines design. With a 5 speed you can actually get a more radical engine to behave for the street and still perform like it is meant to, hence my 3.89 gears-there is a reason all the track paks had 3.91 gears

"I love my Hookers!" and "Get some Strange" probably have a different connotation to non automotive enthusiasts!

Always a problem trying to explain to people what you have in the engine bay.

Pop the hood on my Mustang next a Chevy with a 350 and the Cleveland looks

a LOT bigger. They ask "you got a 427 in that?"; close :D
