How many bolt hold on your timing cover? Gen VI block have a composite cover with six bolts as opposed to 10 or the Gen IV

Actually some Gen V and Gen VI have fuel pump bosses and some do not. My ZZ502/502 is Gen VI and does not.

In general I don't understand the knock on electric pumps. You'll be hard pressed to buy a car today that does not use an electric fuel pump. The basic pump and motor designs have been around for 75 years or so; a well made unti is extremely reliable. Electric pumps are also much more versatile, allowing you to readily prime the carb if you run out of gas for insance, as well as providing a useful theft deterrent as previously noted.

I would only go electric personally. My first hot rod in 1976 was a '73 Monte Carlo and I ran a mallory pump with no return and no regulator. Very simple and easy and worked like a champ.

When this beast eventually does get plopped down into it's final home between my Elky's frame horns, I may end up going electric on both the water and fuel pump...depending on my checking account balance at the time.

But since all this fuss started as a "I-just-got-the-motor-and-want-to-fire-it-up-for-giggles-on-my-engine-test-run-stand" exercise, I'm feeling the pain of the cost of buying a zapped fuel pumper and busy work of hooking up yet another set of wires to my engine test run stand.

Verses...

picking up a $25 O'Reilly fuel pump and pushrod, lubing them up and running some rubber hose to feed the beast some dino juice.

That is..if my cam actually has a lobe to crank the mech fuel pump up and down...still need to determine that.

In the meantime, I may just hunt around for an electric pump to mount on my engine test run stand. Who knows what some intensive pricelining and ebaying may reveal.
