thanks for sharing real-world experience. Looks like I'll stay with the Jr for now. I like the broad powerband from 4000-7000. Just so you know, the cam I'm using now is a 264-266 Comp custom ground solid roller with .702" lift on both. It's got a BROAD power range (which works great in my particular bracket car). I'm running 32x14 tires and 4.33 gears at a 1/8 mi. track....and still was able to run the same 60's as last year when I had 4.56's and 28x10's. I did pick up 6 mph though, from 100 to darn near 107.

I'll probably just leave it alone and bolt the toilet onto the Jr and try my hand at injection. I hope it works as good as everyone said it does....for the money I spent on it.
