What size springs should I use with this cam
I have a Dart Little M block P/N 31131111. Will this cam work in this block or does it require a cam retaining plate? I don't think it is considered a 1986 or newer design.
Why want this cam work with the TBI, I want rough idle with fuel injection reliability
whats the minimum compression ratio to operate this cam efficiently
Will this fit a 1999 Chevy Tahoe with the 5.7L 350 Engine?
What RPM range is this cam ?
Would this cam be safe to use in a TBI application ? I see it says computer controlled compatible. Is this cam too hot that I'd lose vacum and It wouldn't idle ?
