I am not sure how this would work for you, but my experience with the FE engines is they are expensive. If you want a chance for your sons to have a chance to see how everything works and goes together I would suggest talking to one of the reputable engine builders and see if they will sell you a short block unassembled but with the correct pistons, crank, rods and etc and then you could assemble it. We used to have a place here that built engines and they would do that and sell them in any stage you wanted all the way up to a complete engine. The nice thing about it was that everything was matched for whatever you wanted. Correct heads, cam and etc.
1985 CCX has a good suggestion also. And for a street cruiser you don't need 500 horsepower and all the trick heads and such that really run into money.
