hmmm
A few ways to free up some horsepower at little or no cost :idea:
Index the spark plugs-
Homemade ram air with home depot parts-
Get as much advance out out of your distributor as you can without pinging-
Port/gasket match the heads to the intake-
Make the secondaries on your carb open faster-
Lighten up the vehicle-
Hollow out the catylytic converter(s)-
Unplug the AC compressor clutch-
Air up the tires-
Use full synthetic oil if your cam allows it-
Remove that rubber seal under the hood so all the heat will flow out over your windshield-
Then if you save up a few pennies you could swap out the stock clutch fan for a flex fan and get a set of under drive pullys if it applies to you
