Re: grout filling
I have not had any heat issues here in Texas with a my grout filled block, but it is a race only car. I am running the stock radiator with an electric fan and water pump.
Drag racing, because football, baseball, and golf only take one ball to play.
393 Cleveland, iron 4v heads, solid roller, powerglide, 4.56 gears good for 10.02@132 n/a.
