stupid question

[460rogers]

If I used this combo what would i get
454 block
396 crank
454 rods
427 pistons
would it be a 427 or is my math wrong?
I am looking for a low buck internally balanced combo
Any input would be helpfull.

Rogers, you will end up with a 427, which has the same bore as a 454 and the same stroke as a 396. If you don't have a 454 balancer crank and flywheel I can see why you want to stay internally balanced but otherwise it makes little difference for all but super high rpm stuff. I spin a blown 540 to 7400 with external balance and have seen no issues whatsoever after 2 1/2 years.

I was thinking the added counterweights on the crank would be added stress to the crank,especially at higher RPM,s.
also I have this cool aluminum flywheel I wanted to use.

Beware, "cool aluminum flywheel" CAN be "famous last words". All aluminum flywheels are NOT rated for sustained high RPMs, like we see in a boat. I've seen the starter ring come off of a 10,000 RPM (brand name) flywheel just by reving the motor on the trailer, just beware, use SFI approved shit, if in doubt don't use it!!!....................Moneypitt

I,ve got some forged 427 pistons if you need some. If I remember right, they are L2399s

Still just thinking out loud but I,ll keep them in mind.
thanks.
the flywheel does have a SFI sticker thanks for the warning though.
