Can anyone tell me what the stock compression ratio for this motor is. I've got a guy that has a set of factory pistons never used for $50. Is it worth while or should I just go with some aftermarket slugs.

This is going to mostly be a street car, seeing the track maybe once a month.
 
There are a few pistons flat tops, small domes and ones with a small dish in the middle. compression also depends on what head your using if you have a open chamber head and use flat tops youll be around 8-8.5:1 if they are closed chamber heads maybe 9:1. a mild dome might bump it up a full point.
If your heads are closed chamber make sure the pistons are for a closed chamber head. open chamber pistons on a closed head will result in the pistons hitting the head.
