That is a distinct possiblity as we need to get pistons (dished ones in the engine) so sourcing a crank is all I need to do.

make an A15 ;)

77mm stroke.............A14 it is , no matter though as the thing cost me $60 and the A14 is still a big boost over an A12.

Thanks guys , well not so dumb after all. I did notice A15 in the engine number (I think) but I will measure the stroke tonight.

Next anybody know a good source for flat top pistons in the USA or do you just use whatever brand is availible.

Tom

i guess you never know if you have an A14 or A15 till you measure it if someone's fiddled with the engine.

Quote:
The A14 & A15 blocks are dimentionally interchangeable, but the castings may differ cosmeticly. The engines are stamped with the correct code for what they actually are.
The A12 has a different cylinder block as it has a noticeably shorted deck height.
All three engines have a different stroke.

The manufacturers original tag on the firewall, or inner guard, will have both the chassis number, & full engine number of the engine that was fitted at the factory. If the engine in the car does not have that number, then it has been swaped into the chassis. Always check that the chassis number on the tag matches the number stamped into the car, then compare the engine number on the tag to the one on the engine. Caveat emptor.[buyer beware]

Did the same thing - bought a Sunny wagon out of the "Trading post" here in oz - turned up at his house in the dark - read the ID plate on the car said A15, took it for a drive felt pretty good.

Pulled the motor and took a closer look at the engine number on the engine - was stamped A14.

Seller maintains there was no engine change - but when I pulled the head off I measured the stroke it came up 77mm which meant A14.

i guess the thing is aren't all the a12a , a14 and a15 all the same bottom end?

You occasionally come across A15s restamped as A12s to get around difficulties at registration time.

Ive got an A15 without a stamp at all. The bit where it usually is is blank and even the little stamp is blank. Definately an A15 though. I measured the stroke.
