HP vs ET vs seat 'o the pants

[Ron1]

Before I answer that, can I ask about what has been done to the 66 as far as chassis, suspension, roll bar, transmission, traction issues etc. (budget for all that is?)
10's will require a roll bar, and most likely a mini tub to fit a minimum of a 10.5 inch tire under the car. It is easier to make the power, leaving you with the problem of how to get it to the ground. I would suggest a MII fornt end to remove the shock towers. The 351W fits, and parts are readily available for the swap, but you don't want to have to lift the motor, just to change a plug.

Anyway, what else has been done to the car?
