Post your 12 second small block combos

I sold my first Mopar that I strip and street raced to a friend that was into dirt track racing and he asked if I would build him a nice little small block. This was probably around 38 years ago so I said yes and he said how much would it cost him. I told him 5 dollars plus parts and he laughed. With the five dollars we bought a bag of jawbreakers that we all chewed on while building the engine
340 stock pistons and out of the box rings
Polished stock crank recon rods
Slightly polished set of J heads
484 purple shaft cam
Portasonic intake
750 Holley
3200 pound Duster with super stock springs
727 with J convertor
1 7/8 headers
8 3/4 rear end with 4.10 or 4.30 gears
First time at the track for him he went 12.40’s
Next week he took 2nd and ran 12.20’s
We always laughed and refered to it as The Jawbreaker Engine.
