454 Displacement

[challenged]

just bought a 56 chevy kind of a old hotrod it has a 454 that was bored out .030 what would the cubit inch displacement be, thinging about putting displacement numbers on the front fenders.------------Challenged

A stock 454 has a 4" stroke and a 4.25" bore. The displacement is actually 453.96 cubic inches. With a .030" overbore the displacement is 460.39 cubic inches.

And a .060" over 454 computes to 466.87, but everyone calls it a 468. There's some other traditional overbores that are rounded off in an odd manner also.

Thanks Rick and Cnut for confirming what I thought, why do they always call them 462 and 468, I have had dumbasses debate this in the past. Getting to where I dont enjoyresponding any more.

To calculate the displacement accurately, use this formula:

for one cylinder D= 3.1416 x bore x bore /4 x stroke or D =.7854 x bore x bore x stroke

Then multiply that by the number of cylinders.
