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.
well like i said i have pick up 454 4 bolt blocks with cast cranks in them and found steel cranks where you would think it shoud of had a cast crank low power 454 .just look at the crank if it has a big parting line like 1/4 to 3/8 it a steel crank
