I doubt that flipped shorties would work (I think that's what you were talking about). There's just not enough room with the shock towers. If you have the mustang II suspension, then no problem. Custom headers is probably the only way to go. I've just planned on that since square one with my build. If you don't mind, what are your plans for the turbo setup? I have most of the parts for mine but no time to get anything finished (or started in some cases).
well apparently flipped stock manifolds will work http://mmb.maverick.to/showthread.php?t=37473&highlight=turbo i may try and use his idea but alter it for twins and a blow through carb..or atleast single turbo/blowthrough
i'll either use two to4e turbos or one masterpower t-70 along with a a2000 epump/boost regulator you vcan get this combo for around 300!
I would consider using weld els before the stock manifolds. Easy to weld and will flow a ton more than the stock manifolds. I was going to go this route myself, but opted to build a second set of headers (for those that have been following, I built my first set but had to sell them off when I changed heads) instead. The new ones will be 1 3/4" primaries (the old ones were 1 5/8" and with the setup that you are going with would probably work better). But if you use the weld els the size you need are the 1 1/2" (actually measure 1.610" inside opening). Get yourself 3 t's for each side, 2 elbows and some header flanges (3/8" preferred or 1/2" if you can locate them) and slap it all together with a mig welder. If you don't have the skills, you can either farm it out (Brian at BG turbos was going to make me a set many years ago when I first started this project) or go with the flipped manifolds. Either way, good luck with your build and let us know how it goes! PS-are you going with a blow through design?
Don't forget that you want to trap as much jeat in the manifold (header) as you can. The best way is with stainless tubes and ceramic coating. From there it goes down hill to standard tube headers.
i'll most likely be going with a csu carb..but i may just get a bloew through kit to convert a standard holly and thanks for the head up , i'll google that my mig skils are eh... i literaly only used my mig 3 times and did pretty decent..once you get the wire speed right it looks pretty good...i'm more of a stick and oxy guy
Check Stangnet, classic sub-forum. There was a guy over there that prototyped a set of turbo pipes a couple of years ago. It looked real nice last I saw of it and he was planning on making them for sale. They were built into a 65 Stang, which makes them suitable for any 'classic' Stang with a 302 and very likely a Maverick, although I don't know for sure. He posted threads about his progress and a great deal of pics, I think there was even talk of making sure they fit Mavs in the thread. You can compare his thread to our "carbon fiber hood" thread here. It was super long with lots of pics, posts, and updates over a long time. That's about all I can tell you right now. You'd have to do a search or ask around in the classic section.
This is a pretty good looking setup... I would worry about the heat load on the alternator though. Definately would need heat shielding if not relocated. I'd probably even put header wrap on the tube as it passes by the alternator as well. This setup looks alot like the Stang kit I mentioned. The kit has custom tube shorties instead of stock manifolds of course. Then the tube on the passenger side travels lower, since it is not dependent on the stock outlet, therefore it is well clear of the alternator. Also, since it has the luxury of being custom and lower, it travels tighter to the balancer, then it shoots straight up to the turbo.
