Need some advice

I like 600vac holleys as the great allrounder.
Thet work well on stock to well worked slants.
Don't be shy on your head shave.I've had 125thou taken off with no issues.

Here's my Valiat ute std 225/904 with 600vac on Cain manifold and headers.
Gets good mileage and goes well.

The Cain is an Aussie brand of manifold but any Clifford or Offy will be fine.


he isn't goning to change the cam or do any head work so a 390 4brl or a 2 brl will be plenty...
