Re: LS6 454 build AFR heads
I have been running a very similar set to your motor in my 67 Chevelle. Mine differs in that I still have the factory iron heads that were worked over and the L88 solid Flat Tappet cam. I also have the GM intake and a worked over 750 DP on it. I have a TB400 with a 3500 stall converter in it.
This car runs good, and it has lifted the front end off the ground before. With a light car like that, you should have no trouble turning those tires over. This setup should move that car really good.
If it was me, I would get this setup running and tuned properly first. Feel it out, and see how much power that it has. In that light of a car, you might not want more at the current time. Being able to drive the car on the street is the big thing. My set sometimes can be tricky on the street, especially when a bit damp.
