Re: 85 trans am!!!
BOP Q-Jets were 780 CFM as opposed to Chevrolet at 660 CFM. Also, BOP had a straight fuel inlet, used the elongated filter whereas the Chevy was turned to the passenger side and used the small filter. Also, if it's an '85 carb It's an E4MC, meaning electronic. If it is in fact such, use it as a door stop; It's junk.

Re: 85 trans am!!!
Still don't know why you're cobbling together brackets when you're using an SBC, really. I must have missed something and thats no suprise. The 67-up Pontiac V8s use a combination of cast aluminum brackets and steel and things get hairy when you mix different year components. Whatever you do, just nail the belt alignment cuz thats what counts. FWIW, I messed with (and sometimes up) many Q-Jets and in my experience they have too many quirks for the budding enthusiast. No offense intended, it just takes a pretty savvy tech to actually bring one back to it's original freshness and function. They all have SO much wear. But yes, when hunting them look for the forward facing long filter housing-ed B-O-P versions. Pre-smog. The Q-Jet kinda sizes itself to engine demands due to the design. I think you'd be better off not using a Q-Jet unless you're going for the sleeper effect. Just my .02.

Re: 85 trans am!!!
my grandfather brought his Q-jet back to life and has done many im rebuilding it under his eye so I can learn and its done right and cause I want to move stuff around and im not cobbeling to bad all brackets except the a/c are the correct brackets. ill get a pic of the one I have I know one the most commen problem ill run in to is the butterfly valve being loose in its seats. alignment is very key I know im lining it all up with a laser level and make sure its perfect. Because the number one causes of belts coming off is not lined up and slack. who know this may all go bye bye cause im looking at a serpentine belt from an early Tahoe. I will get pics posted when its all mocked up and done I love peoples opinion and advise but it all boils down to this is my car and I want it set up the way I like.

Re: 85 trans am!!!
I can believe a Grandpa would have Q-Jets whooped. Theres just so many warped castings out there its tough to find a cherry. I let a plie of five go on CL a few years ago and said I'd never have another. That was after running an EPS for ten years, I figured why am I keeping these. But now I've got one more, on a parts car. I may play with it one day. You hit the nail on the head though, about having it your way. No apologies ever on that. A man's car is HIS, ftw. Glad toi hear you mention serpentines.

Re: 85 trans am!!!
Does it have the 305 or 350........... The heads and intake manifolds are the most restrictive part of that engine. Put 1500.00 in parts on the engine and you will have a very fun street car............ And don't forget gears for the rear

Re: 85 trans am!!!
If you're using the electric fans only, you'll want two and with a good shroud. You may also want a controller that flips one on with the A/C. Stock dual setups use one fan with multiple speeds and the computer says when and how fast to run them. Q-Jets with wires are the least desireable ones, it may take a lot of effort to make that one work. Not old enough, so its a smog carb. Many would call it a doorstop, seriously. Free is free but I'm just sayin' it would be very unusual to see one on anything that isn't bone stock with all the sensors hooked up and working.

Re: 85 trans am!!!
I'm lost at two radiators... Do what now?
Plumbed oil filter adapter yep. You got a hitch on that thing? Plan to road race it? If not, save the fuss and dough for something else you really require. Again, just an old car guy opinion with no thorns. Oil needs to be hot to work right anyway, if it stays cold and thick you can snap an oil pump drive rod or distributor gear and thats no fun because gravity. Who needs the extra weight, extra oil, and oh half a dozen or so potential engine oil leaks it creates? Not I. Are you planning to use an oil temp gauge?
