Re: Need Engine/Trans 86 c-10

A 454 will simply bolt right on to your existing mounts. There is no cutting/banging required. You will need to get all of the accessory brackets for a 454 but your starter, alternator, distributor and carb will all bolt right on. An awsome all around combo is a 454/th400 with a 3.21 rear axle ratio. The 454 makes a ton of torque so you can get away with a taller axle ratio.
