More RPM from my 390
By Ian Dobson - 10/03/2001 8:27:12 PM; IP 24.68.80.44
I know this sounds like an incredibly stupid question but here goes :)

I have a 69 Mustang with a 390GT? 4 speed in it.

this is what it has as far as know.
Holley 750 DBL Pump
ford alum. dual plane
cam I think is't a SIG Erson High Flow 2 and its 25 years old :(
Pistons I believe they are cast flat top beasties 10.5/1
Hooker Super comp Headers.
3.50 Gears Traction-lok diff

Car runs 13.2 @ 102 MPH and doesn't seem to generate power above 4500RPM, so thats where I shift it at, I'd like to get an extra 3 10ths of a sec before I consider more radical additions.

What should a 390 rev to and still make power, I mean it revs no problem to 5500 RPM but shifting at 5000 RPM the car is a little slower.

Do I have a problem, or maybe is it possible that my cam is worn down and thats why I have nothing above 4500RPM?

and the million dollar question....
what could I try cheaply to make it faster :)
This thread, so far...
