10's on $5,000 ?

Let's keep it correct. No head work. Cam is .427 lift/204 @050 - less than a factory 360 4bbl cam. And you'd expect that with 2.94's? Stock converter?? Now recalculate please....
Recalculate what?

The motor makes what it makes, the car goes what it goes.

If the car is slower than the power to weight ratio indicates..... then the problem is in the car.

Having a car with the wrong gearing and the wrong converter doesn’t make the motor produce less power.

I don’t know how bad a 360 with an aftermarket intake, 750 Holley, and headers, along with some sort of aftermarket cam would have to be to not be able to make 280 STP(standard temp and pressure)corrected hp on an engine dyno.

But none of that matters as far as the upcoming 10-4-5 project is concerned.

It makes no difference what I or anyone else thinks about how it will turn out.
You’ll show up at the track with it...... and it’ll do-what-it-do.
