Default TPI Measurements

Does anyone have the measurements for a stock TPI unit?

Specifically the height from the china wall to the top of TB mounting surface. The search showed some measurements between 8.5 - 9", but I wanted to make sure.

Thanks!

It's the front and rear lifter valley wall. Can you email me the outline you have?

Hey Will, I know what you are looking for. The Accel Super Ram is 9 3/8" tall and the throttlebody is angled down at about 15degs to clear the stock hood. It will scrape a little under hard acceleration.

You mean the web in the middle of the lifter valley? I have a complete TPI manifold on the shelf if you need other measurements.

Maybe 1/4" at the most. If I don't have the hose clamp on the intake accordian off to the side, it will hit the hood when I lower it.
