Tip of the Month

A few issues ago Resto Tip explained the advantage of using a fuel pump relay for those using an electric fuel pump. We explained that the use of a relay eliminated the possibility of poor pump performance due to lack of a strong constant current being delivered to the pump. Most problems occur when excess resistance builds in the wiring. Using a relay energized from a switched source on one side of the relay in order to directly connect the other side to battery voltage can keep the pump supplied with a full 12 volts. The tip generated a lot of interest, one from a reader who is building a ’66 Chevelle, and asked for a typical diagram. Hopefully, it will help to further explain just how to wire a relay. The relay pictured in the diagram is a typical Bosch relay PN 0-332-204-150 available at any good auto parts store. Thanks Douglas!


Camaro Booster

Hi my name is Kyle Reeves and a friend turned me on to your magazine. I recently bought an ’83 custom convertible third-gen Camaro built by John Greenwood. It has a turbocharged 305 with water injection, but the guy lost the paperwork on the car and I was wondering if you could point me in the right direction to get papers on it. Any advice would be much appreciated. I can send pics, VIN, and John Greenwood serial number if you would like. Thank you and I look forward to hearing from you.

If you’re a long time Chevy guy or gal you undoubtedly remember the John Greenwood era, both racing and building some of the most popular Corvettes on the planet. In the ’60s and ’70s, his equipment, mostly Corvettes and a few Camaros, was the stuff to beat on America’s tracks. With that said, not much is known about the ’83 Z28 from Greenwood’s Camaro, but we have research that would suggest that two ’83 Z28 convertibles were built by Greenwood and awarded by Greenwood’s tire sponsor, BFGoodrich Tires, to the highest producing salespeople in the country. Both sported the 305 turbo V-8 built by Greenwood. The only reference I can find for the ’83 Greenwood convert carries a Greenwood ID number GF06014-83. As far as any paperwork trail is concerned, I would log onto www.thirdgen.org, a great site for research tools using VIN numbers and information. Through their site information can be found on how to further research your Camaro and paperwork. As stated the information is sketchy on the Camaros but I’m sure some of our readers can enlighten us. So feel free to drop us a line in care of Resto Tech if you have any accurate information about the greenwood ’83 Camaros.


Crossed Up Ram

What happened to the availability of the small-block cross-ram GM intake manifold? I think it was on Trans-Am cars. Years ago some mag said it was to have GM part number and said it would be retooled. Thanks for any info.

Don’t know about Chevy reproducing the 302 cross ram intake manifold, Terry, but there are some pretty good new reproductions available now. Try Competition Carburetors out of Long Island, 631-846-8899. Also, Heartbeat City does make a quality reproduction under license from General Motors. Heartbeat City can be reached at 586-226-8811 or www.heartbeatcitycamaro.com. The part number is EGP1944A. Be prepared to get out your wallet!
