was speaking to an engine builder (a mate of my mechanics) who reckons its eaiser to keep the standard crank (especially as their is only a minor difference of 3mm in bore and 7mm in stroke from an a12 crank to an a14 crank.
he was trying to convince me that by using a standard a12 block and crank and modded rods, bored out to accept 75 or 76mm high comp pistons with an a15 shaved head and a metal head gasket, it would rev harder and produce slightly better power (although less tourqe) depending on carb and cam selection... he belives that by machining and balancing the a14 crank to suit would create a few headaches (something this old man doesnt want)..
he says to buy new pistons to suit the a12 rods wrist pins instead of moddifying them to accept a14 of a15 pistons.
is he right or just being lazy like i suspect.
he does uild nice 383 308 strokers though... and the sound is fantastic.
