Talking 454 Crank

I wanted to know if it is possible to put a 454 crank in my 396 and if so is there anything that I would have to do extra to the block?

Two different strokes on big blocks, 3.76 and 4.00

The funny thing is cranks that have the same stroke (say a 396 and a 427) are not even interchangeable because of the counterweights. They vary depending upon the bore size of the motor it was intended for.

I'd build the 396 if I were you. Some of the 396's came with 425 HP from the factory.

Unstable, 454 chevy cranks will fit in a 396 block, so will 427 cranks (427-396 cranks are virtually the same). the problem you would have is nobody offers off the shelf pistons for the 396-402 bore with a 454 crank. Lately it is even hard to find 427 pistons in affordable hi-perf pistons ieSRP or Ross or Manley etc. This is because most builders are going for the most cubes, or they are using .250 long rods and 454 pistons.

umm, I'm just going off of what I read in this book. It says quote
Quote:
...Although the 369/402 and 427 crankshafts have the same stroke, they're not identical; the 427 shafts have a heavier counterweight
It also goes onto say

Quote:
Althought cranks of the same stroke are seemingly interchangeable, they aren't because of the counterweights
Guess you can't believe everything you read, plus I never have heard anyone even say "421 Stroker"

sorry for the misinformation

-->get some quality custom pistons from somewhere

To put a 454 crank in a 396/402/427 block you must grind the bottom of the outboard edges to provide clearance for the connecting rods.

Sorry, I was incomplete....You must grind the outboard edges of the CYLINDER....
Sometimes the cranks fit...sometimes not....
Bob...Have you had luck just dropping cranks in? I have heard a few stories of no interference...But not many!!!!
