303.7 3/4 race cam

jknisely · 04-05-2003, 01:11 PM

I need a little information from some of you older motor heads. I am building a 1950 Olds 303.7 motor to put in a 1934 Chevy coupe. The block has been bored .040 over
and I will be running an Edmunds 2 duce
intake with twin Rochesters. I have installed a "3/4" race cam. I have heard that I have to
change the rocker arms and install adjustable pushrods. The valve train on a
50 Olds motor is non-adjustable (rocker wise) and the stock push rods are not adjustable. Any info welcome.

Solid or hydraulic cam? You could get adjustable push rods made from any of the big cam companies. I'm building a 324 myself. I found a set of adjustable rockers for mine, they're out there you just have to hunt.
Just how big is "3/4" any way, you running 2 pedals or 3?
