Hey guys, I am normally on the 4.6 side of the house but, my race motor has now changed to a SBF instead of a mod motor soooo... Anyone have any experience with engine block filler? I was going to fill my race motor to the water pump, run a high volume electric water pump and a good oil cooler. It will be a race only motor never to be driven on the street. Good heads/valvetrain, forged internals, main girdle on the bottom end, good intake, carbed and turbo with 4 core inter cooler. And, yes, I did use the search feature first. Thanks for the help, guys!
