Parts Index

Parts Combination Guide uses 8 typical performance levels from mild to wild. Choose your performance level based on your driving habits, normal rpm range, or the horsepower that you require. If you aren't sure which range to use, be conservative. If you choose too high an rpm range it will rarely be used and you will be disappointed but an rpm range that is lower than you need will still be used. Each performance level suggests the range of camshaft, carb size, compression ratio, header size, ignition, and gear ratios that will work together the best for that performance level. Continue to the parts lists to find the parts that fit your level.

Camshaft and lifter kits.

Valve Train includes pushrod sets, rocker arm sets, timing sets, valve spring sets, valves, and everything for assembling your heads.

    Which Cam Duration In The Range Will Work Best?
Cars (large):  Use short or medium duration, exhaust can be longer.
Cars (small):  Use long intake duration, exhaust can be longer.
Propane:       Use short or medium duration, exhaust can be shorter.
Turbos:        Use short or medium duration, exhaust can be shorter,
                       compression must be lower than shown.

    How Much Lift Is Enough?
All with 1.880 valves get the best flow at .480 lift.
All with 1.920 valves get the best flow at .490 lift.
All with 1.960 valves get the best flow at .500 lift.
All with 2.110 valves get the best flow at .538 lift.
Lifts higher than these figures will add more duration at the maximum
flow point.  Excessive lifts will cause more problems than they are
worth in an engine that is not fully race prepared.

    Minimum Engine Horsepower Required To Reach A 1/4 Mile Speed:
HPq = (0.00426 x MPH) x (0.00426 x MPH) x (0.00426 x MPH) x Weight
