Hey guys,

A good estimate of what a fox-body Mustang with a 351W could do in 1/4 mi would be the 87-93 Saleen, right?? I'm pretty sure Steve Saleen put 351W's in his limited edition cars...

Nope. The Fox Saleens were stock 5.0's.

Unit5302,you mentioned before that the early 351w were 15 second cars. That might be true but also remember that suspension sucked back then. If you drop one of those in a modern fox body chassis I bet anything that it would run mid 14's right out of the box!

The 69 4v heads had the same size valves as the 2v. The 4v had different pistons (which changed the CR I think), a higher compression ratio, along with a 4bbl carb to make it's 40 additional rated hp. I don't know as the heads were significantly different.

As far as the older stang's having shitty suspensions, it's true, but mid 14's is nothing special. A run of the mill Fox 5.0 can run that out of the box as well.

Not to sound unimpressed, but a 1987-1993 5.0HO engine with those mods should be deep into the 13's.

I don't know why everybody see's 351 and get's all excited. In stock form, most of the 351 Windsors are nothing short of a crunchy turd. I can't begin to count how many people throw some old 351 into their car expecting major performance, only to find out they run 14's and 15's.

The 1969 4v 351W is about as hi-po as the stock 351W's got. It's still lackluster in the performance category. With a few mods, you can easily wake it up, but the same holds true for the later 302HO.

Already with a decent roller cam, mild head modifications, and an intake can put the 5.0 into some good hp.

The 69 351 will require headwork if you expect to unleaded pump gas, a different intake, carb, and a better cam if you really want to make some power with it. When those are performed you're in the same boat as the 5.0. Same mods for significant performance increases.
