Finished building the motor and put in a sizable Joe O. cam in it this time. When I started the motor it couldn’t hold idle both in drive or neutral. The idle speed is set at 950 rpm, but it couldn’t keep running. Drilled a small idle air bypass hole in my BBK tb and now it can hold idle very well even in drive. If anyone has an aftermarket tb with a big cam they might want to consider doing this to resolve their idle issues.
