    383- How fast have you made one run in a B-Body?

    Just talking 383, not your stroker. What is the fastest E.T. you have turned either 1/4 or 1/8. I'm running mine, and dynoing mine next weekend at the #MoparVsBrandXstreetcarShowdown in AL. I suspect I will be able to outdo my showing from last year as I had a reaction ring in the trans break...

    I got my numbers wrong off memory... it’s 230 not 234... the lift is .534 so it screwed with my memory... haha but here are the cam cards Comp is the new one, Hughes is the old one.

    Question about 383 pistons

    I was damn near losing sleep over this issue, because the cam was being changed from 208 to 234 and I had to have the car race ready in very little time. Once we actually put it to the test I felt silly for even worrying about it. It runs great, super strong, and isn’t even close. I’ll get a...

    Question about 383 pistons

I was going to advance the cam to buy up some clearance but after seeing the room I still had I just lined it up dot to dot. This is using a 1.74 valve with a 234 @ .050...

    Question about 383 pistons

    I have these pistons (link below) in a 383 decked .020... they live .003 out of the hole, hopefully that gives you an idea of where you would be if you ran them. I have 915 heads and the car runs fantastic on 93 octane using a felpro .039 gasket. If you did choose to get back in it and run these...
