The Sprint 6 package was available in the US in the Tempest/Lemans and the Firebird I believe from 66-67 maybe 68. 10.75 compression a hot cam, factory headers topped with a Rochester Q-jet. The Pontiac overhead cam engine standard version was also available. That engine uses the Buick/Pontic bell housing bolt pattern. I would suggest hot rodding the 250 Cubic Inch Chevrolet engine if you want a six. Port the head get a more aggressive cam, increase the compression and add headers. Do not be afraid to turn it hard, it is short stoked and has steel rods, routinely turned small journal SBC with factory rods 8,200 with no issues (roller cam 331s). I had a 66 Tempest with the Sprint 6 Package, and it would run with a lot of V8s. However, I think it ran lean on 1 and 6 when that Q-jet opened. I lost number 1 piston then number 6 piston then cracked the head in number 1. Pulled it out and replaced it with a 400 out of a 68 Catalina. With the dual Thrush I didn't fool anybody even with the 6-cylinder badges.

It increased the farm productivity and, in general, made life easier because more work could be done with this 'mechanical beast'. My dad dreamed that some day he would have his own tractor with every implement he could get. When he rea
