Here is an online photo:

Nope. I know drain holes. These are hole holes. Each passes through a sub member as well. I'll get a picture the next time I'm at my buddy's.

@Dr. 240Z

My buddy's 73 has two holes that go through the floor back near the outside seat belt anchors. Is this a "feature"?

Could make a great Dilbert comic.

The one with the black valve cover could be interesting as whoever painted it may have done more... possibly in a good way or in a bad way.

OK CO, you went on a bender... yuk yuk.

BOSCH In the last years of the war, no new German tank ever drove without the starter elements from the Bosch factory in Hildesheim. Bosch also had a monopoly position in the outfitting of German Luftwaffe aircraft. Nissan (owner of The Prince Motor Company). Prince had two origins: Tachikawa Aircraft Company Nakajima Aircraft Company

Have you adjusted the valves? That may smooth things out. Also have a look at the cam lobes for wear and the spark plugs for consistent colour across all 6. Often when a 280z runs rough, simply cleaning the electrical connectors will bring it back. It may be useful to do the above health checks before swapping engines so that the electrical is debugged and you gain some useful tuning experience.

L28, high compression, cam, some triples and you are set. Turbo items: HG worries Coking on bearing Cooling on shut down Getting fuel and timing right, Intercooling pipes Heat and exhaust EFI system A lot more to rebuild, set-up and maintain with a turbo.... and how many times will you use the full power of either motor? Put the extra effort and $$$ into the suspension that you save with the NA, you will always be turning ?

Turbo is lot more work and effort. I'd say the 82 P90 is best. Shave it to boost the compression and you are good to go.

He lives ~ 100km from me. The Zamboni guy is closer. I saw one of chad's cars at a regional car show. Nice work. Very retro looking.

Don't sell that Z! It may have a curse.

Yes oil prices fluctuate....I wish milk and beer would burn... they are stable in price. Heating oil is similar to diesel fuel but lower in price due to less tax. It is dyed so that smart people do not put it in their diesel vehicles to save $$ The oil burner is simply a single injector and high pressure fuel pump with a blower. Sort of like a small flame thrower. There are many tools for measuring the efficiency, soot byproduct, and correct ratios of fuel to air. I overhauled the burner and set the air fuel mixture by flame colour. When I called the "burner guy" for a check and tune, I was less than 2% off the mark. Another colour tune example lol. https://youtu.be/H8-7kyD7b28?t=488

Oil in my house. Propane in the garage.
