ok,

so the motor is a Toyo Cup motor, totally stock, SC cams, CIS pistons, early heads to the 39mm intake port.

Ignition is MSD

40mm weber jetting

mains 150
idle 55
air correction 180
e Tubes F3
chokes 36mm


top rpm 7300 (ARP rod bolts, JWE race springs)

so, I drop to 1 5/8 on the headers and the 40mm webers, or should I get 1.5" headers and jet up the 46mm webers?

I am guessing it may be splitting hairs on the set up, the rules are designed to make it even, but I thought I would ask anyways since I now have a set of 46mm webers

thanks

Jim
