thanks my87Z for the LSA input.
thanks AP72 for the cam suggestions-they are right on. i just don't want to adjust solid lifters (i did too much of that in the 70s on C2 vettes. guys would come in and say "adjust my solid lifter cam" i would ask" what cam do you have, they would say " i don't know" so i would have to figure out wether it was a 30/30 dontov cam , or a .027, or an .017 solid lifter cam (they all were a pain)
also AP72, i have much more high speed cars with much more HP, so i don't think my vette will be much of a problem. after all, how fast can you do with a 4.11 in the rear.
my pantera will top out at at 150 MPH+
THANKS OLD RED i put much value on your comments.
