Here is my theory. As far as pistons go forged, if you plan on doing a power adder later or you are going to run high compression. As far as who to get the kit from I would choose between DSS or Coast High. Most of the people I have talked to have recommended doing a 331 c.i. instead of the 347 for drivability and longevity. I hope this is somewhat helpful.
