Bit more than a little bit of machining though. Been there done that. Waste of time.... We also used to machine down 327 Chev cranks into Holden 308's. Thankfully now you buy an over the counter crank to do so.
This was pretty popular in speedway super sedans back in the 70's 80's. Back then the regs stated that you could only run an engine available in that model car.
An mates old mans used to sponsor & spanner his mates super sedans through to the 90's. He ran a chev cranked 308 Toranna early on too.
Some of the
not so successful stuff they told me guys were trying.
