I was contacted by one of my followers on Twitter (@CarRestoration), I follow him as well (love a nice GTO) Jason Horn of Beattyville, KY.
He is currently heal up from an injury but he provided a link to what is a monster power plant that he’s build for his 1969 GTO rebuild.
Check out this how this mild-mannered 375 wants to jump right out off its motor mounts!!
Here’s why: It is a Butler performance stroked factory 375 that is now a 474.
Jason is looking at 650 – 700 HP and he’s connecting that up to TKO 5 speed!!!!
This is his 28th Pontiac engine rebuild.
Rest that injury Jason and drop us a note when you are back at the project.
Best of luck
