Description:
Peterbilt's lightweight model 351 was a worthy successor to the model 350, offering shorter wheelbases and more optimized weight distribution. The difference in sales numbers is very telling, with over 7000 351's being sold 1954-1976 vs 847 350's 1949-1957. It's fairly safe to say that the 351 was the model that really drove Peterbilt conventionals to the success they continue to enjoy.

This mod seeks to recapture some of the magic of this pivotal truck model, including one of its iconic movie appearances!

Helpful Hints:
Pay careful attention when configuring the chassis, engine, and transmission. The standard chassis use double reduction rear axles (Rockwell SLDD) and so only slow ratios are available (4.68 to 5.90). This is best suited to the more 'vintage' engine selections by trading off speed for more torque at the wheels. There are also chassis with Hendrickson RS or Stabilaire suspension and SQHD rears (ratios 3.70 to 4.63) which pair well with more recent engines.

Probably about time this got its own thread. I've been chipping away at adapting the 350 into the more well-known 351:

Smarty! What is that thicker rubber trim around the windshield of the 350s and 351s? On some models of these trucks they have a thicker gasket around the window. And will you add it to the mod?

edit- I think the thicker gasket might just be a thing on the early models of the 351 and on later model 350s. I'm seeing a lot of 1955 Peterbilt 351s that have the thicker gasket.

edit 2- Ok so yes the later 350 Peterbilts had thicker gaskets and then was carried on to the earlier 351s. And I think the early Peterbilts with the thicker gasket did not have the
butter-fly hood style yet and it looks to me this mod will be a mid production/later model 351. Because it looks like the butterfly type Peterbilt 351, so i guess no retro gasket.
