Over the years we've noted that the vast majority of guys are looking for the same thing - a reliable hot rod ideally suited for the street, capable at the track, and striking an ideal compromise between longevity and power gains.  The following setups are ideal for use on stock short block cars running 91 octane or better pump fuel, and drive well with stock gearing.  All of the following kits include in house QC inspection of every camshaft to ensure your individual cam will simply install "straight up." Adjustable aftermarket timing sets, piston relief cutting, and cam degreeing/adjustment is NOT required for adequate piston to valve clearance.  With proper tuning these setups typically manage 22-30 MPG highway fuel economy.

Power Gains: The horsepower output ranges assume a set of aftermarket headers, and estimate a realistic range that can be expected from moderate inlet & exhaust restriction to minimally restricted "full bolt-on" cars.  Thanks for your consideration!
