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It was available on one of the Avanti websites but I believe it's no longer active.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.

Your rear brake wheel cylinders may need rebuilding…one may be frozen, a leaking seal or a bad hose. Don’t go adding something that may not be necessary.

You have to remember...back when the Avanti was built Studebaker (and other car makers) were using pretty skinny tires...not those with wider footprints like they do now. It took less effort to turn the wheel regardless of whether equipped with power steering or non-power.

Somewhere I read the “C” meant “convertible”.

Studebaker owners are very fortunate, indeed, to be able to have access to such records. From experience I know how Mopar and other Brand X owners get so extreme for originality. I owned a '69 Corvette L71...427 435 hp convertible and was fortunate to have its original sales invoice, window sticker, copies of all prior titles, complete service history of the car and the broadcast sheet from on the gas tank. That was an uncommon thing to own a car that was maintained as it was plus all its records. No knows whether Chevrolet has records for them anymore...they disappeared long ago...either lost or destroyed. It's well recognized within the Corvette world that if those records were suddenly found and people had access to them there would be many unhappy current owners as they would find out their "all original" and "correct" Corvette left the factory in a completely different configuration. It's already generally acknowledged that there are more "original" big block Corvettes extant than ever left the factory during the big block years. Having the original records found would be a disaster for the Corvette hobby. Pontiac owners generally do well as the factory records for them are pretty complete and available.

Roughly 8000-9000 Avantis were built. I don’t know if anyone has a firm figure of survivors but I would think there’s a good 50% still around whether running or not.

Much depends on the sound you want. I’ve used both Flowmasters and Magnaflow. Flowmasters will give you a loud, raspy sound that makes you think will shake or even break glass windows as you drive by. Magnaflows give a lower, soft burble at idle and will open up much more as rpm’s increase. Go to each maker’s website. They usually have a sample of the sound their products make you can listen to.

Very true...wavy body panels is more the norm on fiberglass bodies cars. When the '70 I owned was redone the body shop went above and beyond (I paid for it) and made sure the body was so smooth that people at cars shows later couldn't believe it was fiberglass due to its smoothness. The body shop was proud of the car since its presence there sold additional restoration work for them.

What sending unit…gas tank…temperature…oil pressure…which? Different brands can look different but do the same job.
