ok so i've decided to do a small teardown cleanup, hone, polish and rering. On my 1965 shelby K code 289( it was in my fathers 66 gt350 which he piled up in 71 with about 25k on it, it has sat since then).... i'm trying to do this on a currently very tight budget because i've got a lot of money wrapped up in a lot of projects right now... i was wondering if it is safe to use the old cast iron pistons or if they're just going to be a hazard waiting to blow apart and wreak havok inside my engine..... i've already heard a few people say that was a risk but others say it'd be fine i just want some guidance from some guys i trust a little more when it comes to actual engine building
