I am switching out my Holley for an Edelbrock on a new 350 crate motor with automatic trans.
I am confused as to where to connect the return spring. The only video and written assistance is for a manual transmission. Can anyone can help me with placement of the throtle cable , transmission cable and return spring.
Also, can I block the PCV valve port in the carb?

You can buy a universal mount for throttle and trans cables, that mount at carb or intake. I just used an old chrome bracket I had for my return spring, mounted to my thermostate housing. :P
