Post your 12 second small block combos
For a "real low buck", this is how I ran 12.90's at 104mph. Here is what I did. Started with a 25.00 dollar 360 out of a 77 dodge truck. Found somebody to bore .030 and hone for 200.00. I put 135.00 into the cheap speed pro pistons. Rings, bearings, gasket and oil pump about 175.00. Then added 200.00 for J heads with 2.02's. 50.00 dollar swap meet cam (284, 484 mopar performance) and lifters. Topped it off with a used 750 dp holley and LD340 intake. They were about 350.00 total. This totals a little over 1100.00. I bet a thermoquad and cast intake would've performed as good and would've put me well under 1000.00.
I had a 10 inch TCI converter, the tranny out of the truck (did NOT rebuild it) and 3.91 gears with 28 inch tire. 74 Dart weighed 3200 lbs. Drove 1 hr to dragway, ran it as I drove it. Pump gas, full exhaust, etc. Ran this combo 4 years without no problems. Then I sold the car.
