Did a little cleanup on the car this past weekend.
Needs a little more scrubbing on the subframe to get the rest of that factory goo off. I suppose I'll paint the engin compartment too while I'm at it. I wasn't going to but what the hell.
Naturally it started raining once I moved it outside.
Did I mention the car has a hitch? It's like it's whispering ,"Take me to drag week..."
Factory wussy exhaust will not harm anyone ever again.

Got the heads resurfaced the other day. More for piece of mind so I wouldn't sit up at night wondering if should have done it. i also got a spare intake and exhaust valve to take some measurements on. these aftermarket stock replacement valves are crappy when it comes to flow. I'll take some side by side pics. they don't do the back cut on them like the factories. I am surprised at the margin on the intake valve. It's so tiny. I still need to grind the seats then start putting them back together. Then it will be on to the transmission build.
Must... resist.... urge.... to... port........
4 inch downpipe technically fits but 3.5 is probably what I'm going to use. That will give enough room for the wrap and thermal stuff to work properly.
Got some transmission ports in. I ordered the 37 tooth gear and for some reason they sent me two and a stock input shaft. Weird.... I also got the supposedly stronger input shaft, pump drive and 33 tooth driven gear. That should keep me at the 2.93 final drive ratio but with the single chain instead of the two smaller ones.

Have tools, will make stuff. I needed some plugs to seal up the transmission... So I drew some up and printed them out. I really need to start using CAD more often so I can get efficient at it (that was why I bought the printer after all). It took me a little over an hour of fumbling around through tutorials and piecing together what I needed to do. I'll be happy when simple designs like this take me 5-10 minutes.

Out with the old.... The AC was still fully charged so that's good. I should be able to just hook up the lines on the LS4 compressor and call it a day. This engine would actually have been pretty decent had they used it in a normal front engine RWD layout. All the pain in the ass parts that made me contemplate a shallow grave for the engineers was due to FWD packaging.
Trans coming out next and then some cleanup.

Did the car shuffle yesterday in between tropical storms. Since i have the week off I figure I'll yank the engine and trans out while waiting on some other stuff to be delivered.
Lawnmower burnouts! Yeeeeeesss.....
I had these sitting in the cabinet for a few years. They'd look pretty good on the Lumina. that or I'll make some rectangular/trapezoidal ones.

The engineered performance one is interesting as it looks like a normal clutch type from maybe a 7.5 diff crammed in the 4t65e diff. I'd like to get my hands on one to see if I could reproduce it easily on the cheap. Then there are those ones made up of a steel block with springs you cram into the diff. Not a fan of those.Last edited by SuperBuickGuy; June 3, 2020, 09:20 PM.

what a maroon (in my best Bugs Bunny voice)
I'm only curious which of our scientists is going to stop laughing long enough to respond.... so free air is worthless, imprisoned air - now there's power there in the air
and let's hit one more. emissions engineers couldn't care less how much fuel is consumed to make clean air. Sorry Dan, couldn't resist that one either.
