I think they used a 650cfm Holley.

I thought he was looking for a new crab, according to the thread title.

 

And he got me to wondering if my truck might actually have a crab that might actually need replacing too... so I clicked on the thread to see if I could learn the whereabouts of any crab or crabs, as it were, on my truck...

 

But fortunately for both of us, it looks as though it was just a typo.

My friend just dropped on an Edelbrock Performer 650cfm carb on his 366 that's in his bus.

I fixed the title to the thread... now crab = carb!

I tried to edit it and had no luck, thanks for the help.

I bought a 1981 GMC 7000 with a 366 and it's running a little weak. Thinking about upgrading to a 427 tall deck or even a regular 454 engine I can get pretty cheap. Anyone know how much difference between a 427 tall deck and a standard 454 other than the obvious, like torque mounting etc.?

I have heard of a few people that have gone to the Edelbrock in the 366 and in all cases they said it's like a whole new motor. To put one in you will need one with a manual choke and will need a spacer to install it.

Used to own an 81 Chev C70 with a 366 and a Clark 5 speed, and 2 speed rear end...... What a dog and waste of cast iron that thing under the hood was. That being said..... A 427 is a direct swap. The 366 and 427 are externally identical, both using the same crankshaft with internal balancing and both being tall deck. The 454 is a bit more work. I think the biggest problem is the flywheel. I remember a guy who dumped a 454 in 3 ton and had to take his existing flywheel in and have the 454 weights attached as the flywheel/clutch on the heavy trucks is different than a pickup with a manual tranny. Now being a low deck engine bracketry for accessories and whatnot will probably have to be modified so they will still bolt on. Still no huge deal as they are all big block Chevy's. The easy way out is the 427....... no modification or fabrication required.

I would look into the new summit carbs. I am running one on my 67 Camaro. It's great carb, a copy of the holley/motorcraft carbs and you can get one way cheap!! It will still mount like your old Holley and the linkages etc should be close. I have run elelbraocks for years and always like them more than aholley for street cars and trucks. The Summit carb is the bes tof both worlds.

Yeah I used to own one with a 427 tall block, it looks like now days they're pretty scarce unless you want to pay thousands. I'm just wondering how many were ground up in scrap yards and sent to China.

750cfm quadrajet, best carb ever made period. but thats just my opinion. plus you pay what you get for, they are much more expensive than holley or edelbrock
