4.3 Supercharged Chevy

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.

I grabbed a wire with stronger output than my tac could handle.

Ah, I see. Na, I am trying to get the tac signal from the distributer and send it to the Porsche gauge cluster. I would hope that the signal from the GM distributer is pretty light, but IDK.

When I was testing the wires a few months ago some of them, when put to ground through the multimeter (just testing for voltage) would give a blip on the tacho. ME THINKS that means if I give some of those wires a blip from a tac signal off the distributer they will make the little Porsche tac come to life.

This is what happens when you have the plug wires in the wrong spot and your engine says "CHECK YOUR TIMING" and you are like "F YOU I'm gonna pour more gas in the carb". Oh well I really shoulda clear coated that adaptor plate anyway.




And I picked up a piece of garbage on the side of the road today... then I put it on my car.




Well, I was thinking that air, being a fluid, would find the vacancy in the engine bay of my car the path of least resistance... then slap a Z-art top over that vacancy and I'll get all kinds of rumblings that I don't want. SO I wanted to make a belly pan of sorts (to keep that naughty air going out the back of the car). I found a washer machine on the side of the road near my house and I picked it up. Fits pretty well, I just need to do some trimming and paint. BUT I think its gonna do well back there. It fits under the OEM plastic trans tunnel (??) panel; so I don't think any excessive air is gonna really find its way into the engine bay.

BUT at the end of the day I know its just gonna look like I have a washer machine under my car. ROTFLMAO

Dunno if that will work for you guys...

She's on the ground and I charged up the A/C. Now its just a matter of fixing a 2007 Mitsubishi Eclipse before I can back the boxsterado out of the garage. My wife's car warped the head and is currently blocking me in; gotta fix that first.



It looks so mean when its off the jack stands.

Further in the saga of LISTEN TO WHAT YOUR ENGINE IS SAYING. LOL

Yeah, roots blowers don't allow for backflowing of gasses. Apparently I've been running on 5 cylinders ever since I first started the engine. LOL

I'm not mad, I'm actually impressed. That push rod made it through a rocker.

Oh well. In about an hour and a half I had both the heads off stripped and I'd ordered new headgaskets, rockers, and lifters. God I love this engine in this car, its like insanely easy to work on. Everything is so easy to fix and right there. Imagine having an engine on a permanent engine stand with 2 feet of room to work on either end; that's a SBC in a Porsche.
