What do I need to keep in mind when selecting a cam for my 340 that will see significant street, Auto-X, and road course driving, but I would like to be able to run an aftermarket Vintage Air type air conditioning unit to keep it comfortable in summer. I understand everything is a compromise. So given that I want as strong an engine as possible with good mid-range grunt for pulling out of corners and upper end power, where am I going to have to sacrifice on the cam specs? Or am I?
I currently have a quote from Mike Jones for close to max effort SFT cam (without A/C being considered) that comes up at 244/252 @.050" .365"/.364" Lobe Lift 108 LSA. Would that work with AC?
Basic outline is 3700lb car, 10.5:1 compression 340 with ProMaxx heads flowing ~250-270cfm depending on if I get them worked over. 1 3/4" headers, A833 4spd, 3.55 gear (may go to 3.91 or 4.10 later with an OD trans).
