Thread: 400 tpi w/ vortec heads?

Tweet

Should work, Car Craft mag has done a few Vortec head based builds in the past few years. Make sure to avoid Gen II series heads, they have reverse coolant flow. The 400 was produced from '70 to '79, the vortec heads were produced nearly 20 years later, so there was no factory combos. Remember Vortec heads also require and Vortec style intake. For a street motor, a mild vortec set-up should do very well, plus you have the possiblity of using factory fuel injection.

update: now have 062 casting vortec heads and 87 camaro tuned port system. i wanted to use the o.e. roller lifters that the tpi came off of but the dog-bone collars dont clear the cylinder walls. thinking of using solid roller lifters but will the link bar clear the cylinder wall? or will the lifters cause the knock sensor kick in?
