Lt1 camshaft
You would need headers and good springs to match, a retune and probably roller rockers too. Also you should upgrade the clutch at the same time or the stock one will burn up quickly with added HP.Hydraulic Roller Cam. Strong power increase in mildly modified engines with great throttle response. Works w/ stock converter in 383+ c.i. Likes 2000 RPM converter in 350 or less c.i. applications and 3.23-3.73 gearing. Largest choice for inboard/outboard marine applications. Noticeable idle and likes headers.
