8.1 vortec into 1979 k30

Yes, you can switch to the chevrolet performance front cover with a 24x crank/1x cam sensor in the cover, but its expensive and doesn't really get you anything. You can reach up in there and get to the sensor just fine on the side of the block, you just have to remove the starter I think. There was a big problem with that sensor hole and sensor corroding and basically fusing together, making it almost impossible to remove. I'd make sure that the hole is nice and clean and then coat the whole side of the sensor with anti-seize or grease to make sure that doesn't happen

Nice

there is a option to go old school with the 8.1 but it is just as expensive as the mall amount of aftermarket stuff for the efi system

if the sm465 will not hold up time for a nv4500

What do you mean? Like youd prefer to use a NV4500? Or that it couldnt handle it? I think the SM465 could handle it fine, but it would be more work just on the transmission to engine side of things, rather than the floor/ fitment side of things

yes I am a big fan of the 91-94 nv4500 I saw a post forget what number it is that said he could tear up his 465 and a 4l80e was recommended that is also a good option imho I do not know how much the 465 can take I think it could take it just fine but if some thing dose go wrong I think that the 4500 would be a good way to go

does a 8.1 have a Gen III LS bellhousing?
If it does, the early gmt800 had option for manual transmission (6.0, not sure about 8.1) , so id use that simply for its designed to fit eachother already. If it doesnt already match , then I would say go to the nv4500 because of gear count and shifter quality
The Sm465 is a very small stout unit, but the shifter is weak point and needs custom fixes to get not feeling like your rowing a boat

The sm465 is also known for falling out of 3rd gear, needing gl4 lube to not attack the brass synchronizers or whatever it is that GL5 isnt friendly to. While its a classic, youre already going through the work to put a fuel injected 8.1, might as well give yourself a fighting chance for any fuel economy and allow your torque to be used to fuller potential.

Now if you want to use an Automatic.. .you have an engine thats designed to mate to a 5 or 6 speed allison from factory!
