Which Stroker kit????

[MuscleMustang95]

Trying to figure out which stoker would be more reliable and beneficial. The car is going to be used for street strip. Im expecting around 600 HP. Here is my planned setup, let me know If a 331 of a 347 would work best??

BOSS 302 block
Probe Forged rotating assembly
AFR 205cc Heads
ISKY Custom Cam
Edelbrock RPM II Intake
HP Stage I Turbo Kit w/60mm Turbo

If you want a 347 and you're using a Boss block, just do a 4.125 bore x 3.250 stroke and you've got your short-stroke 347.

He's right, you're wanting to use a block that opens you up to SO much more than what a factory block offers. The short stroke 347 uses what everyone refers to as a 331 crank but with a much larger piston. Shorter stroke = more revs. Big bore unshrouds the valves to make much better use of big heads.

For what you're wanting though, you're going to need MUCH bigger than an RPM II intake. Think Victor 5.0, Track Heat/R-Series, or at the very least, a systemax

Well doesn't the Victor 5.0 RPM range form like 2500 to 6500 or something like that.

You have to remember that the "ranges" provided by manufacturers should be adjusted based on the size of the motor. A Victor 5.0 on a 302 wouldn't have the same range as on a 418 ci windsor.
