New Crate Engine 454 up and running
Little over a month ago my 1991 pace arrow blew the engine. Finally got it up and running again with a new crate engine. Just about dialed in now. One problem: seems to be backfiring thru the TB...

Maybe you have a plug wire crossed, or the distributor timing off by one tooth. Premium fuel should always be run with these big engines. Not only will it run smoother, you'll get better mileage, it will quit detonating/exploding the fuel, and probably run cooler in the process.
