4A-GE first experience

[DRFT]

Greetings to all!
I need help of the experienced 4A-GE builders.

My story...
Arriving at the miniDH event in the nearby town of Krivoy Rog I accidentally found and bought for only $250 stripped down and not a complete 4A-GE.



For my track-day project http://ae70.blogspot.com/

My plans for the motor are as follows:

* Reliability consisting of low-cost OEM parts;
* Horizontal carbs. (Weber or Dellorto);
* MSD ignition;
* and so on.

My questions at this stage consists in the following:

A. What kind of pistons were in it?






B. With piston size - 81.65 mm and diameter of the cylinder - 82.10 mm pistons what new I need to get?




Does it make sense to build the engine on this block?
Or is it better find a new 4A block?

I would be very grateful and appreciate any advice.
