    OEM 9.25 sure grip carrier looks

    I replaced my 8.25 rear-end with a 9.25 sure grip. When looking at the carrier the outside was machined and looked like it was 2 pieces. Was the OEM unit as cast or machined? I'm thinking the carrier might be an aftermarket unit. When I was able to try it out the sure grip gave out to a one...

    Engine build question

    I'll make this short. I have a 400 block that has a 4.375" bore. I have been looking at the Keith Black 240 pistons in a .030" overbore, so 4.372". Keith Black has the piston to wall clearance at .0025" min in a street motor, and .005" in a drag motor. So my question is this the piston I...

Reading on this site, this is wrong and that both marks need to be at the 12 o'clock position for the motor to be at TDC on #1...

    Aftermarket heads on a smogger 400?

    How much horesepower do you think one would get by putting on a set of stealth heads on a smogger 400? You should see about a one point increase in C/R with the stealths being a 80CC head. I'm putting in a hughes whiplash cam and was thinking about putting on a set of heads while I was in...
