Pretty good trick getting 42 cubic inches out of .030" overbore.
|
You'd need a bigger crank with an overbore to reach 496. If that's what you've got, great. If that is what you were told you had, oops!
|
454 +.030 over = 460
|
Damn, hate it when the bubble pops.
You first move is to find out exactly what you have. Cam... ect. |
I can only wonder what the engine is, and what may have been done if someone started out telling you that engine is a 496 with .030" bore. Might be time to drop the pan and heads and make sure it's all real before proceeding any farther.
If it really is a stroker 496, then I wouldn't go the TH350 and converter you have. As much as I love the TH350 behind my big block, it's very mild compared to the torque that a 496 can put out, and I doubt the TH350 would last long. |
I have a .030 over 454 ,mildly built and have already went thru 2 rebuilt 350 turbos,went to a 400 and never had another problem
|
either way if you have a big block with anything major done to it, I would just go ahead and throw a th400 behind it!
