12 second 340

Mike right now the car has a stock (as far as I know) 72 short block. So its a low compression 340

I have a LD340 intake with a 600 Edelbrock on it. I also have a 650 doubble pumper.

It has 1-5/8" headers and 3" exhaust

727 with a 10" converter and the 3.23 gears. I like gear in my cars so that will be the first thing to change. Probably 4.10s or 4.30s
