Thread: 454 4-bolt main

Tweet

the date codes on the block and heads match up with the year of the truck.

it is for a fact a 454 and it is standard bore with 100,000 miles on it.

so it probably doesn't have a steel crank then? did they put a steel crank in 1tons in 76' or does the size of the truck not matter?

truck had an automatic tranny.
