How to get my car into 12 seconds?

I had a combo that won't get you in the 12's, but is a great place to start and was a lot of fun. This was a 360 with the smallest purple shaft they made. I believe it was a 268/272 split duration. Have a valve job done on the best set of stock heads you can find add the correct springs and have them shaved 30. Windage tray, LD340 or another good used intake, carb of your choice 600-750 CFM, I got lucky and a very good TQ 800. The intake could be a pain to get installed. This was a great combo in my 72 Duster with a 323 and 4 speed. Ran 9 sec flat in the 1/8 and got 18 mpg. Took this car on a few 600+ mile trips.

HOLY CRAP!!!!!! It just hit me. That was 22 years ago!
