A while back we were discussing a 351C in a maverick. I found the old thread, but we never addressed a boss 302 in the maverick. Does anyone know if you can run 351C stock exhaust manifolds on a 302 bogus boss in a maverick? I have 351C 2bbl heads with the correct pistons and manifold adapters. I know tubular makes some headers that are very expensive. I need to know if stock 2V cleveland manifolds will fit in a mav with the "bogus" 302 boss. I know ratio411 indicated he had a 351C in his car. Any ideas?
exhausting idea If any use them off a 70 Stang, very narrow so they should fit. One thing is the exhaust ports angle differently then the 302 wedge heads.
2bbl Stang Yep, and you had to make sure it wasn't a 351W. They cam with both the 351W & 351C in 2bbl. No reads much about them because it was the first year for the Cleveland 4bbl. Besides a 4bbl manifold will work just as good. Bolt pattern is the same. Just use 4bbl exhaust gaskets.
Boss Mav engine bay is wider then a Mav, true but the 71-73 Stangs where much bigger. Along with the fullsize cars. Personally I'd use headers for a 69 Boss 302 Stang. Port size isn't going to be that much of a issue. Tube size is the bigger issue.
RR, I realize that the 71 stang would be bigger than the mav but would manifolds from a 70 351C stang be any different than a 71 351C stang? I agree, I don't know if the 69 Boss headers will fit the mav body. Due to the fact that regular long tube headers are "tight" I would imagine 351C headers are extremely tight. You wonder if the tubular automotive headers are simply headers from a different application or specifically designed for the boss in a mav?
Where to start? Well here goes, I've used both 2V and 4V ex manifolds... both work! Now you can use standard motor mounts but for manifolds to work on the motor you have to mash or remove the part of the shock tower that extend just under the shock tower and just above the motor mounts. If you are not sure what I'm talking about putting the motor in two or three times you'll will find out. After trying to get a Boss motor to run (($5000.00 in just the motor) and thinking I could, I found that the words from older and more wiser people to be true. If you want a conversation piece then go BOSS, if you want to go fast then do something else. PS DON"T get the motor mounts that tubular automotive says you need for their headers, they don't work!!!!! (unless you plan on cutting and welding) but the headers do with a lot of cussing! Hope I've helped Terry Gates AKA Bossmav
thanks bossmav What if I used the tubular motor mounts and the stock manifolds. Would any cutting be necessary. I have all of the parts to build the boss using a roller block! And, yes, you helped a great deal. I just purchased some 2V manifolds as I'll be using 2V heads. If at all possible I'd like to talk to about your experiences with installing the boss 302. If you don't mind email me your phone number. wm12345@hotmail.com PS-I'm an MCCI member though I don't know to many members.
bossmav, would like to talk to you also I have bought aussie 2v heads and they are in the shop now. I'm going to stay 302 ci but I'm going to use 5.4" rods and make a long rod motor. I'm not going crazy with the heads because they should flow enough already. Just hardened exhaust seats, bronze guides, screw in studs, some bowl work and some polishing of the runners. Plan on using Mannly undercut valves and some good springs. Do the tubular headers fit by themselves or do you have to use their motor mounts with them? Are they a pretty nice header? Can you email me your # also? w_frahler@msn.com Thank you, Ward
