Our little budget combo's have been with 440 Source kits. I have built their 440/512 and raced it for 5 years, and built their 400/512 and I am on our first season with it. Both pump gas, 1050 4500 carb deals. Both run 9.70 and are pretty reliable.We run the girdle they sell with it.

I am still working on the tune up, but last week I nailed a 6.202 at 110.8mph in the Gold Cup here in NY. Tinkering with carb tune, spacers, timing, tire pressure, etc....Lanunch at 2500, shift at 6400...

With over 12:1, my combo would run in the 9.50's or better...You have an E-body, so I would step that up to their 440/543 kit...Torque is king! Keep the rpm under 6500, and it will last.

Heads are Indy EZ1's basically out of the box.
