Hmmmmmmm--
Little jimmi 228 replaced with larger displacement Chebby 235 and the whole truck starts vibratin at speed. Prolly a lesson in this for GMC truck owners. Need to be careful when replacin those jimmi motors with the more popular chevy engine--tear up ur runnin gear with the more capable higher speed motor.
I'd check that front end--tie rod ends and king pins--might want to look at those motor mounts too--drive shaft and pinon gearing--beef up and fix whatever you need to--gud motor you got there--good idea to replace those little 228/248 engines with a stout little 235. :p
