Planetary ball superchargers need a certain amount of friction to operate properly. If the fluid is too slick the planetary balls will skid rather than spin and roll and develop hot spots and fail.

Was the lower radiator hose changed? If it’s the old one the inner spring could have rusted away (or a new hose missing the spring)…and the hose is collapsing under vacuum and acting as a coolant blockage. Another possibility is a wrong or defective radiator cap. If your car has a closed system and a cap for an open system is there coolant will not return to the radiator. If the cap cannot hold pressure it will run hot. Also…was the system burped after being flushed and refilled? There be an air bubble blocking coolant flow.

It draws in outside air from the cowl of the car. If you look outside at the base of the windshield through the intake grating you'll see two intakes under the square covers.

Myer's Studebaker, Nostalgic Motors and Studebaker, Intl should all have what you need.

Try a test light on the 12v wire to see if it’s getting power. If not then you need to find out why.

Single-plane intakes are better for high rpm performance but a dual-plane such as the Performer are better at lower rpm’s and better all-around performance.

Call Summit Racing’s tech line…explain what you have and your concerns. They will give you solid recommendations.

I can't get the sheets to load. If you send me a personal message with your email address I'll send them that way.

It was available on one of the Avanti websites but I believe it's no longer active. If I still have a copy I'll post it...might take some time looking.

Avanti Motors went to the 350 engine in 1970 with the start of the RQ-B series. The last few RQ-A models would still have used the 327. But...as already said...there could have been some unused until much later. The intake would likely have been what was standard on a Corvette of that year.

I don't know how much these will help...they're from some time ago and vendors could have changed or dropped their parts numbers...but it's what I have.
