The 350 small block Chevy is loaded with potential. Just a camshaft change resulted in a 15hp and 30-plus tq gain. This is a quick weekend upgrade that is affordable and results in good power.
Note: Hot Cam P/N 809-12353923 and 4.6 rocker arm kit P/N 809-12367346 require the valve guides to be machines for proper valve guide-to-retainer clearance when using the stock 350/290 heads.
