What other engines will fit into these 55-59 trucks? I someday would like to find one of these (after my other projects are done) and was curious what all I could stuff under that stubby hood  Indy

These Heavy Duty trucks used the bigger 322ci. Buick engine in '56, & '57, & the 348ci. Chevy engine in '58, & '59. So I'd say yes. | | | | | Joined: Mar 2004 Posts: 6,214 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 6,214 | I believe almost any V8 will fit with little to no sheet metal modifications. As Spanky said, Chevrolet used the 265, 283, 322 and 348 in the 55-59 LCF's. Shane installed a BBC in his 1957 LCF, check it out here; https://www.stovebolt.com/ubbthreads/ubbthreads.php/topics/940994/1.htmlI have a '56 9200 LCF that has the 322 and Powermatic 6-speed Allison automatic.

Just trying to get some ideas going for me and whoever else may read this later on.

V-6's fit completely under the Viking-style cab-overs,in the early to mid-'60's.Same with the 409/427 B.B.'s. They shouldn't take up any more space,than a B.B. (Big Block).firewall mod's may be required,depending on which transmission is used. I think most,if not all T.F.,and Blue-Chip L.C.F.'s firewalls/trans.tunnels were designed for SM 420's

Now to start saving my pennies!!!!! Indy
