Re: Plans for a 478 build.
I think the hard part with big boost on a 478 would be finding one in any condition to use. As to high rpm. I am cleaning out the core motors at the shop. There are six v6 engines. Ones a 478. A couple of 401 and the rest are 351 engines. All have broken rods and one of the 401 has a busted crank. All of them came apart in the mid 4000 rpm range. I have an old Buick pull through turbo on a 305. Its set at 8lbs.
