A And A+ Block Interchangeably?
Best Answer DeadSquare , 13 September 2019 - 05:44 AM
I gather that "Least cost path" is important, but do examine the bores of the replacement block for wear, feeling for a lip where the top ring comes to at the top of the stroke, and the hard shine, called glaze, that drops the efficiency of the rings.
So that nobody says afterwards "Why didn't anyone say that":-........Proper advice in this case really ought to be that you rebore the replacement block and use the old clutch / flywheel, crank, rods and new pistons.
If nothing else, makes sure that you have had a look at the condition of the bearings in the eventual engine, marking the bearing caps before you start so that you know what goes which way round and where.

Have you found an A block with crank, rods and pistons, or just the block ?

Yes, the CR will be lower, but on the whole, the octane rating of fuels seems to be dropping world wide, so I'd just accept that it is a 25 year old example of a 75 year old engine and enjoy it as it is.
If you want performance, the low compression will be an advantage if it is supercharged.
