4.3 Supercharged Chevy

[Qingdao]

It sounds good... Just like a well muffled truck. Just what I wanted. If you're in a parking lot and I'm idling you'd be looking for the S10. LOL







I did unfortunately blow out like all of my intake manifold gaskets with backfire... Might have something to do with my nitwit plug wiring, but that gives me time to make some new ones. Also, gives me some time to trim the UIM down a little to allow for better timing control (the big distributer can't do a full 360).

All the wiring is done; just have to wrap it and tuck it. To give a tentative timeline I'd say a week or two and I'll be on the ground ready to tune the old edelbrock.

Wow, you are not wasting your time for sure. Post a video if you have one, looking forward to seeing how it runs!

What`s that gauge on the charger? For measuring boost pressure?

Its just an oil pressure gauge. I have the Porsche low oil pressure light hooked up for the dash, but I knida needed something to "plug the hole". Figured a gauge would be nice. I was gonna put it facing forward so I could see it in my rear view mirror, but the tint is so dark.

You could use an MSD distributor like the link below which would give more clearance and a timing box which would improve performance and look really good doing it.

I got a skinny one... But I kinda LOVE the clean look of the single wire distributer. I mean the 12+ wire hides under the lip in the back so you can't see it; then the 6 plug wires just come out. SUPER clean.

Its just a little grinding anyways.

I found my coolant leak; dunno if I mentioned that. Apparently I broke some kind of outlet or something on the overflow reservoir. Well it isn't used in my application anyway so I sealed it off.


With proper wiring it fires up every time, just as a SBC should. I'm tickled pink every time I fire it up. But cause I destroyed the adaptor plate gasket it doesn't run for long. I'm gonna have to take the SC off and re-make the gaskets.

As soon as Amazon delivers my super cool Mr. Gasket heavy duty gasket paper I'll be able to let it idle and play "find a wire" with the tachometer. Figure thats the simplest way to figure out how to get the tac working. Just strip the wires from the harness and plug in the tac signal.


I can't get a video to upload here... IDK why. Maybe I can try a link from FB?? oh well.

Careful. I cooked a Chevy diesel truck tac I got at auction doing it that way.

I can't think of any other way to get tac signal to the gauge cluster. Like every tac information out there is how to put a silly aftermarket tachometer in a car... nobody wants to use the oem tachometer with an aftermarket engine.

I got the tac to blip once when I was testing the wires coming out of the DME. So I figured one of them if energized will make the tachometer move as it should. After all I have 6 pulses for every 360 degrees... just like an H6.
