Re: Holley 500 on 250 2v
a 500 holley is not to big.... Look at it this way a 253 holden v8 comes out with a 800cfm carb..
With my old motor in my cortina i ran a redline 4 barrle manifold, with a 650 double pumper, and pacy pipes, and a 2 1/2 exhaust and a monster cam and big 2v clevo valves full rebuilt bottom end , no need for twin pies it will sound like a claped out old v6.
This pulled 165 rwkw on the geelong gordan tafe dyno...i then fitted a quadrajet, and when the secondarys came in it was awesome...
on a 2v 250, i wouldnt go much bigger as the heads even though are much better than the old log head they arnt up to scrach when compared to a crosflow head.
500 will be fine and as a few people have said get it dynoed and jetted to suit
