does it have to be the original crank,because you could do the a14 crank into the a12 block
conversion dodgeman is doing,plus many a 1200
rally car.you could bore the block to 76 mm for 1390 cc's,or 77 mm for about 1430.just use a12a rods & a15 pistons to get the correct pin height.should get you close to that hand grenade a12,with a lot more engine life,plus
retain an original appearance.if,however,you can find an l14 block,you could probably use an
l18 crank to make it 1770 cc's.
the lz14 head that errol acquired recently was from a formula atlantic/pacific engine that someone i know imported into australia.the
engine sat around for years before he could even get somebody to buy the head,& the bottom end was never sold.
