Re: 59 GMC 270-336 swap.

You can bolt a SBC into that truck without doing any cutting or hacking. That was my reason for suggesting it over a quite expensive task of putting in a "stock 336" Meaning that later the SBC could be replaced just as a 235 can be replaced with what ever engine 71 K15 feels appropriate at the time. Painted the correct GMC engine color for the year 99.999 % of the people who look under the hood won't know the difference anyhow but the truck will be drivable and enjoyable/

The other way is to just drive it with the 235 and collect parts to put a 336 in it and have everything there and ready to do a swap in short order with little down time.

77 C 30 dualie, 454, 4 speed with a 10 foot flatbed and hoist. It does the heavy work and hauls the projects around.
