Sooner or later, I'm gonna put my 4.56's back in. The 4.88's served the 340 well, but now it's a 374 in.(3.58 stroke)with light internals. The bobweight is 1807 and it revs pretty quick; enough that I'm on the rev limiter for the last 300'.

Present 60' is 1.49 and best ET is 10.95@ 119.7mph in 73 deg air. I can't remember DA for sure.

Anyway I'm guessing 1.51-1.52 60' and definitely some more mph. Car is 3085 w/me in it.

Anyone care to guess? It couldn't possibly stay the same or improve 60', could it?
