What size Webers to use 40 or 46s
for a 79 911SC CIS, short stroke 3.2 (9.3:1), 964 cam profile, SSI, + 2 in 2 out M&K muffler, and light weight flywheel.
I was at a get together at the local brewery the other day and one of the DE guys told me I had to go Webers. He was running a stock 78 SC and had 40 Webers. Since I am a 3.2 should I be going 46s? I do autocross and hope to do some DEs once the car is fully sorted. 40s seem to be more available can they be made to support my engine?
Thanks
