Hey Joey if i were you id weld instead of bondo. Im going to be talking to my friends stepdad when i get back from South Africa who restores mopars and is pretty good with welding as i want to smooth and paint my bay this winter along with removing a/c and whatnot. Bondo like someone earlier said will eventually rattle out.
Your going to be better off just buying a complete stroker kit. The budget kits don't really cost that much more. By the time you have some one build you a 306 your could have had a 331 with all new parts. I would also stay away from DSS motors. I've talked more than a few people that had there DSS motors go south in a very short time.
The only way to really fill the holes in your fire wall is to weld them up.

Thanks for your advice. I think at this point i am just gonna Re-ring and bearing the stock block, and also do some ARP hardware, with a main girlde for the hell of it. Probably bore it over as well, and throw some nice pistons in for boost.
