My T-bird ran 5.50 flat at almost 2900# with a stock block 557 with tfs streets and some epoxy work in the intake side. This was with some not so ideal chassis tuning. My A-head 557 did not impress me nearly as much for the extra money and time spent on the combo.

the current motor I have to use until I get the big motor done is no turd, it ran 6.60s in my fox with 8.5 tires and 100% bone stock factory suspension and I had to be 3200 lbs for that class, it may run close to that 5.90, at 2700 lbs and way better suspension

I'd hold off on buying any parts until you see how well what you have runs. Might need less than you think...
