So I have a nice, running 1976 Motor Home 440. I'm putting this in a 1970 Coronet, 727 automatic, 3.23 sure grip. I live in the arctic, so I can't just bop down to my local machine shop. They are 700 miles away.
I'm not looking for the worlds fastest car. A mild 440 is perfectly adequate for my needs so I'm trying to do bolt on mods.
I have a Sig Erson magnum grind cam. I don't have an intake yet but it'll be dual plane with FItech injection or similar. I have headers, there will be dual exhaust.
My question is heads. I understand these engines were low compression with poor heads. Is there a stock iron head that I can put on for a worthwhile gain? I'm hoping to not have to swap pistons because of the machine shop thing, and I'd don't think my low compression pistons justify aluminum heads.
Or am I wrong and need to go to different pistons? I will if I have to, I'm just hoping to not have to.
