A friend and I are looking at a buying a '69 Cougar which has a 351 Cobra Jet from a '74 Cougar. Anyone know anything the engine. I mean I know it is based on the Cleveland but anyone know the rev limit? Or anything else of interest about this engine?

In 1974 it was a low compression four barrel carb engine. This looks to be a pretty good guide to 351C engines: http://reviews.ebay.com/ebaymotors/Ford-351-Cleveland-Engines-Key-Facts-amp-Information_W0QQugidZ10000000001410755QQ_trksidZp4506.c0.m17

The cars on ebay right now and the bid is at $430.

low compression = good turbo candidate.

Anyone know what the compression is on this engine? Other then "low"

Supposed to have really good heads, high flow, actually too big for regulat street use. Good starting point for racy motors.

Well if this comes into fruition, there might be a '69 Cougar at $2009 Challenge.

It's a dog. Low compression, way too much port area to make power anywhere. There's a good reason why Ford quit making Clevelands.

If they had designed it ten years earlier, before emissions regs ruined the chance to make top end power, then the Cleveland would have been king. Unfortunately, our reality is the one that happened.

Ford made higher compression versions of the Cleveland.

Well, true. However, they all were "closed chamber" heads, with nice quench pads. The low-comp 4v, and all 2v, were open chamber heads with HUGE combustion chambers, so you'd need some pretty good sized domes to make compression, and you wouldn't be able to use as much compression because of the lack of quench.

Look up "MPG Port Plates". The exhaust ports were actually so big and poorly shaped that you could block half of it off and make more useful power. Blech!

Don't get me wrong, I like the 351C. But I'm stuck in 70's think, where it's okay to have sewer sized ports and who cares about velocity? While we're at it let's throw two Dominators on top as well.

You'll need to log in to post.
