Thank you for the detail! I have the Th-350. I don’t believe it’s the stock transmission but I definitely plan to change the seals!You will need a different flexplate. The original 1985 engine has a 2-piece rear main seal style block and crank, the crate engine uses the newer(better)1-piece rear main seal style block and crank. Crank-to-flexplate bolt pattern is different. Flexplate-to-torque converter bolt pattern will be the same.
You need a flexplate for a 1-piece rear main seal SBC, with the correct diameter to match your old one. It will either be 14.1"/168 teeth or 12.75"/153 teeth.
Diameter has to match the old if you want it to also fit the current starter that is on the old engine. Starter nose cone has to be matched to the flexplate/flywheel diameter.
Near as I can tell, everything else is either in the kit or you can transfer it from the old engine.
Hope your old transmission is up for the job. If not fairly fresh, I would at least put new front and rear seals in it, and change the filter and fluid.
If your Elky has the Th-200, don't expect it to live long and don't even bother rebuilding it, swap in something stronger.
I don't think they used the light duty 200 trans behind the 305 though, but I could be wrong.
Note I said Th-200....not the overdrive 200-4R used starting in late 1983.
I would not buy this engine, it has a big cam and low compression heads. This makes for a very fuel hungry motor for the power it puts out. This is essentially a rebuilders idea of duplicating the GM 290 horse crate engine. If you need to just get the thing back on the road this is good enough, if your looking for a hot rod engine, this is a big cam with the wrong pistons and heads and in a 2 bolt block. The GM version new uses a 4 bolt block with essentially the same internals.
Add to this a TH350 with a stock stall converter will not be a happy camper with the cam in this motor. With that, auto transmissions wear at almost the same rate as the engine, so when a fresh motor gets connected to them they have a bad habit of failing in the not to distant future, so this is another expense you need to consider.
Generally in the past I’ve found the best crate deal is to buy the GMPP 265 horse version of the 290 engine, throwaway the heads put on aftermarket Vortec copies with a conventional manifold bolt pattern and upgrade the cam and your money ahead with more power than the 290///sometimes claimed 310 hp, getting better fuel mileage out of it as well. Actually on the 265 HP short block with the cam that comes with it and vortecish type heads you end up with a 300 horse engine with way better street manners than that 222 to 224 degree cam gives. The 265 horse uses the old 929 cam which depending on the heads and intake with stock exhaust manifolds delivered from 180 to 300 horses out of 350‘s. Better heads like 64cc dual quench chamber sometimes referred as Camel Humps and a Q-Jet were rated at 300, with 76cc open chamber heads and a 2bbl from 180 to 250. With aftermarket style Vortec chambered heads your staring at an easy 300 to 330 horse motor depending on the details.
Your call obviously but if I wasn’t over a barrel I rethink this a bit.

Well, I’m not too concerned with fuel economy cause this is not going to be my daily driver. I am always open to any input. What if I put better heads that would match that cam? Or should I look for a different crate entirely. I’d like to keep my budget under $4,000 if I can get away with it. Like I said in the original post I have zero knowledge on what to buy for an engine swap. I have tore down and put together several motors so I can do the work I just have no clue what to buy.
