I found a 454 4 bolt tpi rebuilt with 10k that is in a 93 dually for 500.00---win? He said engine was a 95. Id convert it to reg. carb since it be going in the 63---anything you guys know about swaping it over to reg. carb set up-it can be done right? Just carb emission yank diffrent intake and thats about it right? Complete 454 engine ready to just drop in with it being a 4 bolt and 10k on its rebuild for 500---sounds fishee...The builder of it is suppose to be giving me a call. I can hear it run before pulling.
