My 1973 K10 Chevy Cheyenne

Tacoma 's can have a manual , and even Gladiators have a real half assed cable shifted manual , with odd ratios and a clutch that can overheat easily .
There are no vehicle engineers worth a damn in today's market.
Yep, everything is now throw away and disposable. What this transmission ordeal on my F150 has taught me is that they no longer rebuild transmissions either, they just make you buy a brand new one.
You can buy remanufactured 10R80 transmissions but most shops won’t touch them. They send them off somewhere that rebuilds them. Even my local guy who is an old school transmission guru said that when they go bad they are so finicky and complicated to rebuild that they just sell you a new / reman unit.
I picked his brain last week. He basically told me all modern transmissions are crap and not made to be rebuilt.
Sounds like a certain manual transmission that came in a certain generation of wrangler back in the 00s...
More reason to keep your old stuff and learn how to work on it yourself. Much easier when it’s not overly complicated. This Chevy is so easy to work on it just puts a smile on my face every time.
Okay, so the Tremec TR-4050 swap is on the way. My neighbor was nice enough to let me use the loading dock at his work to have it delivered too so they waived the cost of freight shipping.
I got the swap from a place called Silver Sport Transmissions that came very highly recommended. They include everything in the swap from the Advanced Adapters bell housing to the pedal assembly, clutch, flywheel, etc. The guy I spoke to said it is everything needed for a complete swap including bolts and fluid.
I'm very much looking forward to this transmission. People seem to love it and from what I'm told it was the natural successor to the NV4500. The 6.16 1st gear, 6.03 reverse, and the overdrive 5th gear are going to make it a blast to drive.

Cool ! Is your engine internally balanced , so you can use a normal flywheel ? This is the only hang up I can potentially see . Additionally , 1 piece rear main small blocks used a out of balance flywheel different from 2 pc. internally balanced Chevy's . You know we will be riding your butt to get this swap done !

According to the place the engine came from it says that the engine is "externally balanced front and rear for reliability and smooth operation":

This is the flywheel they sold me with the kit:

The specs on the flywheel per the invoice say, "McLeod Steel Flywheel, 460130 SBC/BBC 2 pc seal, internal balance 168T 30lbs."
Do you foresee any issues?
I've got all winter to get this swap done. The truck is in pieces in the garage so I'll tackle this almost as soon as it arrives.
I see a giant red flag Chris . The flywheel they are selling you won't even bolt up to the engine in your truck. This is before you get to the 800 lb. Gorilla in the room , of engine balance . Maybe contact Blueprint and get their recommendation on a manual transmission flywheel. 1. For the 1pc. stroker crankshaft they used in the build since the build is externally balanced. Otherwise this is a total nightmare in my opinion.
I just sent him an email and let him know. He's usually very quick to respond.
Thanks for letting me know, clearly this is something I didn't know / overlooked! Good thing is they aren't going to ship anything out until Friday anyways.
Also, my bad. I linked to the wrong engine. This is my engine:

Taken from the specs:
Internally Balanced Front - Externally Balanced Rear
Does that change anything? I suspect it doesn't but I just wanted to clarify. I emailed BluePrint to see what they suggest.
My research suggests I'll need the McLeod 460265 flywheel and the McLeod 560222 counterweight kit.
It seems a little odd to me with the internal front , external rear , however it is possible. 87+ SBC with 1 pc. RMS are like that , but factory 400 SBC's and 454 BBC's are external balance front and rear . High end stroker engines spend the extra money to build internally balanced crankshafts. At the end of the day you definitely need the externally balanced flywheel , CORRECTLY WEIGHTED TO THE 3.875" CRANK used in the build. Chris , this is critical .
Thanks for the info. I will await Blueprint's response. It does seem odd because that 383 stroker I sent in the original post (the wrong link) is externally balanced front and rear. The 396 stroker for whatever reason lists as internally balanced front and externally balanced rear.

I don't know enough about engine building, but how do you get the flywheel correctly weighted to the 3.875" crank? I assume you can't just slap on counterweights without knowing how many you need on there, right?
Correct Chris , Properly done engine balancing occurs at the time of build . The rotating assembly is balanced and component weights are equilized using bob weights to determine the correct weight front and rear , including the torsional dampener and the flywheel / flexplate , ( and at times the clutch assembly ) . There is a lot to correctly building an engine.
Am I setting myself up for a big problem here do you think? I’m asking that because again, I don’t know how you would correctly balance a flywheel with counterweights unless the engine was spinning and you had some sort of balancer machine.
