hello richard
i inquired about a cam from a cam grinder and he spec'd pretty much what was in there except a 108 lsa whereas the z302 cam uses 112, probably for emissions or efi. i told him it was installed 2 retarded and he suggested 4 advance, by the time the chain stretch and everything else is accounted for it is probably pretty close anyway. the 6g rpm chip doesn't lend itself to too many rpm's, and the engine simulator indicates peak hp around the mid to high 5's anyway with that cam. doesn't leave much room to keep the pedal down

judd 5l? thought i was doing good to remove the truck flywheel....
