72 duster resto
Left spring - for my comp thumpr cam
Right spring - came on the heads - Bryan mentioned they're not enough spring rate for my cam
Im a little nervous using this cam now. Bought off a member here but I don't know how the shorter spring is supposed to hold a higher spring rate than the taller ones on the heads... I dont know, first time builder so just a gut reaction.
Option A - just go with it
Option B - pull the thumpr cam, keep the taller springs on and order Bryans matching performance cam from IMM engines that works with these springs. ($325) Sell the thumpr cam and springs?
