340 Cam Kits which ones work with a stock block

Rumble suggested [email protected] without me knowing the details you can go from the way obsolete comp 268H with less lift than stock (chevy grind)
to a Hughes SEH 1629BL-12 with .495 lift on the intake
the Voodoo 60302 (may be a RB number) is .475 lift
Howard has a lobe with a half inch lift at [email protected]
several good choices- post up the details and get dialed in
