Ford 302 SS build

[B/S 428]

I looked at the 69/70 351w combo because I have several mustangs, once again there's a reason no one that I know of is running this combo rated at 290 HP, I wanted to run it years ago because 69s are way cool but after doing the math I put it on hold, the rated HP is to high so I did a street bracket build instead..Brian Seaberg 627

We ran a 95 Cobra R back in the late 90's early 00's. It was 351W. Had the F3 GT40 heads. We ran in it F/S. Went high 10's. weighing 3300 lbs. rated at 300 HP. Wasn't a roller motor. We were surprised when we took it apart for the first time when we started to build it as a stocker.

So that's 490-500hp....that's impressive for a non roller gt40 headed 351! (also the first 351w that I've seen make any power with "stock" heads, lol)

We don't use calculators, we use dyno's and time sheets. LOL

Unless you run at a DA of zero or negative then you are racing with (less) uncorrected HP.


I do have those 1 line calculators that produce those high HP numbers, they make people feel good about the engine they built. But if you run a good computer program which simulates your run the HP and et / MPH match up pretty good.

Let me just add, Larry Meaux's ETA is a great program for analyzing time slips if anyone is interested in this kind of software.
