Rochester 4bbl to Edelbrock Swap
As you can tell from what I say below I am pretty new to all of this. I'm learning as I go. I have an 87 trans am 305. My Rochester Carb is leaking and metal inside is warped slightly. I know a lot of people say I should never get rid of my Rochester but I also am doing this to learn about cars and would love to perform a carb swap. I ordered a bunch of parts but I need help knowing if I missed anything.
Here is my order list.
Edelbrock 1406 Performer 600 CFM Square Bore 4-Barrel Air Valve Secondary Electric Choke Carburetor
Earl's Performance 761066ERL Vapor Guard Carburetor Hose 3/8 in. ID 10 ft. Pre-Cut Vapor Guard Carburetor Hose
Edelbrock 4405 Signature Series Push-On Round Valve Cover Breather
Spectre Performance 4708 Throttle Return Spring Bracket
Mr. Gasket 19 Throttle Return Spring Kit
Edelbrock/Russell 641030 Fuel Pump to Carburetor Line Kit
Edelbrock 8008 Carburetor Stud Kit
Edelbrock 8134 Chrome Fuel Line
Edelbrock 2696 Four-Hole Square-Bore to Spread-Bore Carburetor Adapter
What else do I need to make a proper swap and have it running efficiently? I know I need to get a vacuum advance distributor, and I heard something about a torque converter kit but I wasn't sure about that. Any info would be great about what I need to get also and what I should expect and if I accidentally ordered something I don't need. Thanks

Re: Rochester 4bbl to Edelbrock Swap
When you bolt that adapter onto your stock intake manifold, then bolt on your carb and your air cleaner, you'll find out the hood won't close. Things are already close without an adapter.
Get a rebuilt Q-jet for a late 70's, non-computer controlled Chevy car, not truck, car, and a vacuum advance HEI distributor. Everything will bolt right up, you won't have to worry about vacuum lines or throttle cables, or adapters. Granted it won't be a polished Eldlerbacher controlled vacuum leak, but it'll work.

Cam, you say u want to learn.
Why not just pull the Roc. carb and spend $20 bucks for a rebuild kit
and rebuild it yourself?
You say the carb is warped/bent?
Just disassemble it on the bench and get out your straight edge!
Used Q-jet parts are cheap and easy to find!
IMO a Q-jet is miles ahead STILL today than a knockoff newcomer.
