Budget 360 build

Bang for the low buck is a 5.9 long block, eBay rebuild kit, good machine work and a cam regrind to the low 230's area for duration. Add a Air Gap intake, eddy 750 carb and off you go. Don't forget you'll need a passenger car oil pan and some kind of LA distributor.

With a well chosen converter and the proper gear, you've got a solid mid 12 second street car.
