What cam should I get?
My honest opinion is the XE268 is still alittle to big.
The first car a built was a 69 Satalite. It had a 318, 904 and 276 gears. Being a first time hotrodder I swapped in a 280 (228 @.050") .480" lift cam with a 108lsa, a Eddy perf, intake and Eddy 600 carb. The car was a pig, wouldnt idle under 1000rpms and would hardly move. The stock 318 2bbl would walk all over it. It sure sounded good though.
The truth is at the time I knew nothing about tuning a carn or the proper way to time a motor but even if I spent the time sorting the tune out it still would have been to much cam for the motor size, compression, gearing and converter.
