454 specs

[txhunter69]

ok im confused ive been told 4.25 is stock and that 4.00 is stock on my 454 which is true

[chevynovaman]

4.0 STROKE IS STOCK 454, MY 496 HAS 4.25 STROKE CRANK

[obsessedtruck]

Depends on what it is on the 454. /// 4.25 Bore, 4" stroke.

hah see this is my confusion lol

[signsbyesa]

yea stock bore is 4.25, crank is 4.00, 4.310 bore w/stock 4.00 crank
is 468, change the stroke on crank to 4.25 w/4.310 bore u got
a 496 stomper, for a factory block that is the best and biggest
bore you want to go with unless you get a merlin, and then
your car will go....whaaaaaaaaaaa whaaaaaaaaaaaa :wink:
