Be sure to do the compression ratio "math" to be sure you have a reasonable effective compression ratio for the cam you plan to use.

The last "long rod" 225 (7 inch rod) set-up I did had a .024 negative deck after a light clean-up cut on the block.
With a flat top piston, .040 head gasket and a 60 cc head it had 10.1 static compression and 8.0 effective compression with a cam that has a 65 degree ABDC intake valve closing point.

I'm suggesting that the lesson for you today, is to not have the block bored until you have pistons in hand.

That's what dads are for. Learn to like it......there's a lot of kids that don't have dads that can, or are there, to teach them.
