Not too long after getting my malibu, i changed out the metal type fuel filter that was installed between the mechanical fuel pump and carburetor for a see through glass type. It was the mr gasket brand that has the silicon o-rings on the ends with the replaceable filter in between that you...

Probably nothing new.... but has anyone here tried it? https://www.enginelabs.com/engine-tech/mixing-e85-with-pump-gas-getting-higher-octane-for-less-money/

This is more of a trivial question than actually wanting to use one. If the EGR valve mounted to the intake on the top side gets its exhaust from the center of both cylinder heads... what is the two ports on the intake that sit directly in btween the exhaust port and intake port, it looks to be...

Seems much easier to pick the EFI system conversion of your choice, but when it comes to finding the correct tank to use, not so much... unless you are lucky enough to find a NOS OEM GN tank. This seems to be the solution over the others that feature a low height dog dish or partial style...

Im toying with the idea of replacing the GM spreadbore designed ZZ4 intake, i dislike the choke/egr pads, currently not used and blocked off anyway and i only plan on running with holley squarebore carburetors, both intakes run idle to 5500rpm... worthwhile venture or waste of money? ZZ4(pic 1)...

I plan on going with "Edelbrock Pro-Flo 4" EFI in the near future and noticed that the injectors are mounted straight up instead of their past design(90s) that had the injectors at a 45degree angle that faced the injector bottom straight at the back of the intake valve, i noticed LS intakes have...

Anyone use them for carburetor orifice size checking for air/fuel metering calibration? I recently bought the .011 to .060 set(Accusize) as well well as the .061 to .250 set(Shars)... these are the "Minus Class ZZ", meaning they are made with -.0002 calibration. If you use a digital caliper to...

Im in need of a new protective cover for my '79 malibu(2dr).... just something basic but sturdy, the car sits in a covered car port out of the weather, any suggestions? Thanks

Since im still on carburetor duty, i came across a used 600 metering block for cheap and decided to modify both upper and lower IFR and the PVCR channels for practice. Knowing full well theres aftermarket billet metering blocks available that feature the same, affordable enough, it doesnt hurt...

Looks to be time to change them out, so Im running a ZZ4 engine with cylinder heads that use a "D" exhaust port, but using 1 5/8" headers what looks to use an oval port... would it be best to try and use "D" port or go with oval port exhaust gaskets? Having no idea what headers came already...

Learn something new everyday.... this way never crossed my mind versus the compressed air method.

This guy(LUKE) is an engineer by trade and has done a great many things, this is just another one in the bucket, just for us carburetored guys. Fascinating

Not sure how else to title this.... theres a slight stinky gas smell inside the car while im driving. The car doesnt have the charcoal canister or the bracket, apparently it was removed by the prior owner(s), the vent tube from the gas tank has a small K&N like filter on it, not sure if the...

These two are what im working with along with my ZZ4 crate engine, im currently using the SA770 and i've almost got it firgured out, i havent tried the SA670 yet.... for those that has had both or either one, what has been your experience with them, good or bad, problems, fixes, etc?

Has anyone ever used one on their carbureted engine along with or without an AFR guage? I plan on hooking up an AEM WB02 guage soon, i would like more tuning capability with my Holley SA770 carburetor to keep my ZZ4 in tune with what the engine wants, for now im going by feel during...

They have a built in mini L.E.D that lights up after fuse is blown, makes it much easier to find and replace than trying to figure out which one after a main device or accessory stops working... anyone here use them?

Has anyone ever bought from "ClassicCarWiring" dot com? They have been around for many years, their diagrams seems laminated and colored, which is great. For my year malibu - https://classiccarwiring.com/products/1979-chevy-malibu-el-camino-color-wiring-diagram

Since my malibu sits more than its driven because of the colder weather for now, till warmer weather sets in to drive to classic car shows, swap meets, drive ins, etc.... whats a good unit? Im thinking the DELTRAN units... but not sure if the 12v/750ma, 12v/800ma or the 12v/1.25A will suffice...

The Wheelman... 4doors can rock too if you let them.

For SBC,.. whats the difference? I recently bought a Carter M6900 so i can have a steady 6psi of fuel pressure w/o the use of a regulator. The original pump that was on my ZZ4 engine and the delphi unit i replaced it with, have the same pump arm shape versus the carter unit i just bought...
