how to hit 400hp on a fox stang

Here's a combo 5.0 Mag did - it made 425flywheel horses/435lb ft ... was very streetable and had a broad power curve (useable power) :flag:

DSS 347 ~ Comp XE266HR ~ AFR 185 ~ Comp 1.6rr ~ RPM II ~ BBK 70mm ~ Pro-M 75maf ~ FRPP 30lbers ~ BBK 1-5/8" long-tubes ~ MSD distributor ~ 42psi fuel pressure ~ 14* degrees initial ~ 9.8:1 compression.

99% of the cars on the road couldn't touch you. :hail2: :spot:

The only down side they stated was it's inability to blow clean emissions (cam) :notnice: ....

On a 306, get a good h/c/i setup with 9.0:1 and charge it :nice:
 
the holley enigine package is designed to put 350hp at the crank and not the wheels, they did a test of it in 5.0 magazine and it was something like 290 to the wheels, 350 at the crank. A N/A Motor cranking out 400hp will not be to streetable, but with the addition of a nice forced induction part thats not to hard.
