Re: 1967 tubbed C-10 build questions *HELP*

Level @ the carb/intake surface = 3° down @ the rear of the motor.

Internet research states the rear pinion for a typical street driven vehicle should be equal/opposite of the trans output yoke (3° down @ the trans output = 3° up @ the pinion). Hotrodders reality is this is tough to accomplish when things are changed vs stock so some compromise might be required. A high powered track type vehicle might need the pinion @ or below zero to counter the differential twisting forces depending on the quality of the rear suspension set-up.

For the track, a 1pc shaft is best.
Gearing & tire size for a track vehicle should be dictated by the engines expected RPM range. Check in w/these guys & start reading some build threads....

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
