Beautiful Butler-Powered 1970 Pontiac GTO!!
From John Hadcock:
“1970, 455 block, bored 40 over, with Butler rotating assembly.
S**t forged crank 3 1/4 inch stroke with eagle 6.8 inch rods custom Ross pistons.
Edelbrock RPM heads 64cc New Ferraro intake and exhaust valves, Harlan Sharp 1.65 rocker arms, went through all the heads.
Ported and polished I can’t remember it’s flowing around 314 CFM. It has a turbo 400 transmission with a TCI 3500 stall full manual with transmission brake.
Ford 9 inch, 389 gears with a Detroit locker. I am the second owner bought it in 1997 from the original owner.
A lot of it would not be possible without one of my best friends Sean at Spann auto machine. Sean did all the machine work top to bottom, boring, honing with torque plate, decking, milling everything and he let me do part of it myself and would oversee me and has taught me so many things.
20 some years ago, the same friend Shawna myself did all the painting body on the car. It is all metal except for the fiberglass hood that I don’t have on it right now lol.”
This is pure Pontiac power.
All the parts in this build are available on our site, or you can get the whole combo as a shortblock or longblock kit ready for assembly.
