Intake port design / manufacturing optimization.

Yeah, I do like that about the LS motors, Chevy dropped that shared port thing.


Unfortunately, all that is available for the 4.3 are just factory Vortec heads. I forgot the flow rate, but it boils down to a max of about 50hp per cylinder with stock heads N/A. Not too bad, but that exhaust is definitely a restriction. I just look at the glass half full and say it saves my transmission some heart ache

FWIW my cam is just large enough (212 duration at 450 lift) to give me optimal air flow without being a burden on excessive lift. I should be able to hit a good 7k RPM and still make power.

OOOH boy the shiz is getting real.

I got my block back from the machine shop. Just need pistons .060 over; this ain't no 4.3 its a 4.4. lol I round up.




Of course rustoleum black.




AND I added a second pane to the back glass. I was not satisfied with the sound/heat deadening that a single 1/4" piece of plexiglass can provide. I also put about 15 pounds of sound deadener to the firewall under the carpet.

I also re-did the window tint. While the pre-cut stuff is easy to use; it was short. Like half a cm short on the bottom so when the window closed all the way (door closed) there was a strip of non tint on the bottom.

Very nice. I guess nothing really can go wrong on such a classic OHV V6. Unless you blow it with a big charger Btw, what happened to the original motor?

I wouldn't say the M90 is too big. Its no Detroit blower after all. I'm hopping to get about 6 or 7 pounds of pressure.

No idea about the original motor. Guy I bought it from said that it was an IMS failure, but IDK about that guy, same guy used a rag to adjust the headlight... I honestly didn't really care enough to check it.

Pistons should be pressed in tomorrow.

The Box is all like "Please be gentle good sir" and that Chevy is like "HELL NA; I'MA RAM IT DOWN!"





But seriously I'm so close gotta get longer push rods and figure out a correct belt length... then its just a matter of sliding this bad boy in that purty gurl.

O M G... Everybody talks up Kennedy engineering.. Oh man Kennedy is the bomb digity. Oh Kennedy makes some sharp shiz. BUT Dagnabit (I'm using softer words) I was gonna do some real hatting on Kennedy the other night.

I went to put in my trans on the KEP adaptor plate. I had previously (as seen on this thread) mocked the engine and trans up in the car. No problems right??? But when I went to put the trans back in for real this time I ran into a big snafu. One of the bellhousing bolts for the SBC is in the same spot as the Porsche bellhousing. I know thats not necessarily KEP's fault, but at least they could have not made a hole there or made some kind of note about it. SO I took the trans back out (what a pain). Cut a chunk out of the Porsche bellhousing.

THE Next attempt at re-installing the trans... I had it all bolted up with all the bellhousing bolts in place. And I went to put the starter motor in. CLUNK I hit the Porsche bellhousing. Apparently you have to cut out another chunk of the Porsche bellhousing to get their starter to fit. OH man I was cursing when I took the trans back out.


ANYWHO, alls well that ends well. I cut my chunks out and re-installed the trans.




^^^ Thats the area in question that anyone following me (I doubt there are those as crazy as I***) can use as reference on where to cut.


Here is the old girl sitting all pretty in that engine bay.... I just wanna cry its so beautiful.




So I asked on FB and someone politely responded to my inquiry, but I'm retarded and even more so when it comes to electricity. What color wires, or which pins do I need to make wires go to to make this sensor work. I feel like this is a VSS which is something I want and I accidently hacked it off. Does anybody have a wiring diagram I can follow the VSS wire to a source or know off the top of their heads which pin on what I need to make a wire to make this work?








***Or just touched in the head??

Not sure if that helps you any way, but on my car this connector is blank, wasn`t used and capped off. The only cable that comes from the tranny is the reverse gear switch. Perhaps it`s optional and the speed signal for the speedometer is coming from the ABS sensors?

The connectors on the trans is/are either the neutral safety switch, and/or the reverse lights switch. The speed comes off the ABS reluctor on the hubs.


Badass project. I love the supercharger sticking up. I can't wait to hear it shriek.

I guess you guys are right. Its not like me to just toss out a connector; especially not one that came off the trans.

Shriek it will, soon enough.

I got all the coolant things sorted. I have the coolant temp sender in the heads. I don't know what kinda temps thats gonna read; I might move it to the intake manifold as thats the OE location on the Chevy truck.

Looks like I'm just held up by a clutch slave cylinder. Then I just have to re-assemble the exhaust, drop the car off the jack stands, and wire it up.

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.
