    One more question please, the rear main is leaking a bit. I think a 440 has a 2 piece seal but does a Wedge Mega Block have a 1 piece?

    Need big block help

    i'll look tomorrow but right now I think its Indy EZ. The dyno sheet was run with a carb not the EFI and the timing is locked out and set to 30*. When I'm done reconfiguring it'll be controlled by the EFI. I have FiTech on my own 340 and it runs well so I was elected (volunteered) to try and...

I'm just...

They called it a 501. I found 246 8330-M on the block casting number. My research keeps coming up the block was born as...

    exhaust backfire

    Im back to ignition.. pull one wire off at a time to see if its one cyl. With that big of a cam it would be hard to hear a miss at idle.
