Thanks for the kinds words Mike! I'm getting close to having my Vette out on the road so I can run the TKO through the gears. Over the past few weeks have been rewiring the whole car and fabricated a new sheetmetal dash w/GPS gauges. Doing my best to keep it old-school look with modern technology. Its going to be a great cruiser and I'll have some new videos/content coming soon for the build so stay tuned!

TKX is an AWESOME transmission - good luck with your swap and thanks for the comment!

Thanks Eric / I have big plans for it aesthetically too and I'm excited to get it back on the road- Thanks for the comment!

Hey Steven / I really was just looking for an overdrive and anything beyond that is icing. I don’t think you can go wrong with a 6spd though as you’ll have some more versatility on the highway/interstate (as I understand things, the magnum basically gives you 2OD gears instead of 1 / typical final ratio of .8 and .63) / thanks for the comment!

Thanks Jaivette / I'm excited to get it out on the road and run it through the gears!

Are you talking about the key cylinder - shaft to the wire harness? I actually removed it from the column and replaced with a modern electronic switch key which feeds power to the hot side of the relays in the car - so - guess I didn't use it / good luck with your upgrade - you will be happy with a TKX from SST!

295/50/R15 rears and 235/60/R15 / hope this helps!

Replacing a transmission is not too hard - key is getting the car high enough off the ground that it's easy to work on / I have a 2 post lift which is nice, but if you manually jack it, having high jack stands is key / thanks for the comment!

I didn't wire up the neutral safety switch, but it's really easy to do (basically add the switch to the relay circuit for the solenoid). If you want to keep the mechanical speedo drive with the OEM gauge, I'm pretty sure they make make electro-mechanical sender adapters that allow you to keep your OEM gauges - and - will be compatible with a TKX / your vette too. Good luck with the conversion!

stay tuned / have a C3 transformation movie in the works, but have some other C3 content on the channel if you are interested / thanks for the comment!

Hey @williammorrison1433 - you want to check flywheel flatness with an indicator (magnetic base on the block, nearby stand, etc) -then- you need to turn over the motor by hand from the crankshaft snout in front (lots of aftermarket 1/2" drive SBC sockets that will do this). Not sure spec but likely looking for something .002-003" or less. The clutch will wear together with it over time, but a new or resurfaced flywheel should be nice & flat. After that, you want to bolt on the bell housing and attach an indicator to the flywheel (magnetic) -then- verify bell housing runout is .005" or less on modern transmissions. If you have too much runout, it puts extra stress on the input shaft-case bearing and they will have accelerated wear-could have hard shifting. You correct this by purchasing offset bell housing pins (or you can machine them like I did). From the factory though, if you have the original bell housing and the locating pins are original on the block, you should be good to go! Here's a link for a typical SBC 1/2 crankshaft attachment www.google.com/search?client=safari&rls=en&q=SBC+1%2F2%22+crankshaft+tool&ie=UTF-8&oe=UTF-8

@@TacoJoe thank you, I'm hoping that I can get what is needed for what needs to be done for my engine. It's a 455,1973 block, I'm trying to keep everything Pontiac other than transmission. Although the basic principles should be the same. Now I have to figure out a way to save your instructions so I can refer back to it once I get to that stage of my build.

hey its not too hard (don't despair) - just get a magnetic base or clamping dial indicator and you'll see its pretty straightforward what you need to verify (its not hard - just need some patience to make sure its right) - Harbor Freight sells a clamping indicator for 40$ and this will do the job to check both flywheel flatness and your bell housing runout too / link @ www.harborfreight.com/clamping-dial-indicator-63656.html

Hey Mitch- I'll see if I can put together a follow up video - I have a 3.70:1 rear end ratio. The PERFECT ratio would be 3.55:1 because 4th gear runs a tad too high RPM wise at 40mph - then a shift into overdrive and you are at 45-50mph/slightly speeding on the average city streets. That's why I think 3.55's are a sweet spot with the OEM tire size. On the highway: 3.70s are great in OD (I think it's 0.68?). Big picture: an OD transmission upgrade is a excellent choice for a C3 / I think most will like it.

yes sir (but not too much)

haha- I'll see what I can pull together here. My goal is to have the C3 makeover all wrapped up by spring.
