OK, without dragging a wheel out and weighing it...........I'll say #3, 21 pounds.

From the rear cover side.............you can't see the tag from the input end.

In 2001 the difference was $6K, so I'll say #1, $8500.

IIRC the 2001 Avanti used a 5.7L LS1 as installed in the Camaro/Firebird. The ratings I found for the 2001 Camaro/Firebird LS1 were 310 hp (the Firebird apparently had an optional engine 325 hp. So.............. I'll guess #3, 325 hp.

I'll have to do something I rarely do -- disagree with Gary. The ratio tag is at the 7:00 position (#4).

True, but they also stated that multi-viscosity oils were an acceptable alternate.

I thought it was every fuel stop........... check oil level and cooling system level (although they must not have watched the film about not opening the radiator cap on a hot engine!).

Yes! To blow carbon out of the cylinder that was knocked off the plug when it was loosened. After operating for a few seconds, then shut the engine off and remove the plugs. How many of you follow this factory recommendation?

#2 -- 1.260

True!

I have not owned an Avanti, but have several R-series powered Larks & Hawks. All of them have a fuel return line that comes off the fuel filter and goes back to a nipple attached to the fuel tank. I always thought that at least the Studebaker Avanti's had these also, if not also the early Avanti II.

This one I had on eBay sold for $35, I'm sure to some Corvette guy. Don't think I would have paid that much for a 50 year old fuel filter, but was glad it sold.

Listed this on eBay to see if the Corvette guys would bite, doubt if there are many late '60s/early '70s Avanti II's being restored to the level that they would want a NOS fuel filter. fuel filter on eBay

Here you go Ed. It was used on at least '68 & '69 Corvettes, probably other hi-po GM engines. Note the return port.

Was that Roy Hecker's car, with a supercharger? Seems like it was maybe the last 1979 Avanti II but not sure.
