Hello, I own 76 F100 shortbox with a 390,c6 and a 9" with 3.00 gears. This truck is my weekend toy in the summer and I'd really like to add some more power to it. The 390 is just a rock stock 2bbl however it's been rebuilt about 5 years ago and run like a Swiss watch, I was looking at edelbrocks top end kit 2044 and was wondering if this was something I could install or would it just end with wreclimg my bottom end? I also plan on putting a shift kit and 2500 stall in the truck as well as a 3:55 posi. I'd appreciate any help or advice with this, im open to suggestions, thanks
