bOre VS stROke BBC TECH
okay a guy i work with happened to mention to me the other day he has a 402 bb lying around that he wants to sell for 500 bucks heads and all says it has a forged crankshaft etc etc. anyway i was thinking about stroking it out for a future motor by putting a 4.250 stroke crank in it which would make it the effective cubic inch of 461.2 which a .030 over 454 is 460.6 would this combination run as fast or neck+neck with a 454? i realize the smaller bore would hurt the flow on the heads and the longer stroke will wear out faster.
