8" vs. 9" convertor

If you are going 7.0/100 with a 1.74 60ft, and 600hp you NEED A converter!!!
Edit: .... but you'd better have the traction/suspension to hook it up.....
Most 7.0/11.0 if they are sorted out and prepared right = go in 1.4s somewhere.
A 124 MPH well prepare car should go 10.5ish and 1.3 to 1.4 @ 60
5200 RPM in Traps = I would be looking for another tack unless you
were at 1/8 mile.

Our little Red 68 Valiant small block street car that won the MATS Street
Legal Class last week has 3:91 and a 29 tires at 120 MPH was 6250 thru lights!
