What do I need to bolt a c4 to a boss 302, just have engine . What bell housing , flex plate ,tourk convertor will work . Boss is a 69 thanks ........James
The same stuff you would use on a regular Ford 289 302 351. Not sure why you would do this but it is yours.
Prolly a ratchet ....3/4" sockets deep and shallow (& 11/16")......1/2"............9/16th" typical FoMoCo sizes wrenches I would suggest a higher stall torque converter.....maybe a manual valve body....minimum of a shift kit (NOT B&M!). You sure this thang is a BOSS 302?! (BIG ports!) solid lifter camshaft??They're pretty rare. Go get 'em! 6sally6
Small block ford bell housing small block Ford Flex plate starter for flex plate tooth count converter if your choice ( mild to wild ) related nuts, bolts, brackets and fasteners and fittings. pretty standard stuff really, easily available used or new
What I remember about the Boss 302's is that they were a bit doggy on the bottom end. I think they all came with 4 speeds. You had to keep them wound up to get them to perform. I worked at a Lincoln/Mercury dealer in the 70's and we had an Eliminator 1 Cougar that had a Boss 302. It always had a dead battery because the sales force couldn't use a manual choke. Sold it to a young lady, early 20's, who drove it for quite a while and had no complaints; she kept it wound up.
Ford sold the Boss 302 with a 4-speed only for a reason... Unless you use a high-stall convertor, you'll have a real dog.
A set 4.57 or 4.72 rear gears and a 3000 stall or so converter would put it in a sweet spot for some stop light action.
Only thing I can think of is you’d have to use the earlier flex plate, not one from the 5.0/302 era. Also, isn’t there a plate/sheild or something between the transmission and block?
Yep, regular sbf stuff. Buddy of mine ran one in a Maverick drag car. Ran good! It does take a pretty loose converter to make it run good. You can turn that thing 7500-8000 all day. They have good stuff in them.
I hate to be a spoil sport.... but a Boss 302 doesn't fit within the date parameters of posting on the HAMB.
everything from the heads down matches a windsor. block oil pan distributor cam interchanges really only heads and intake are cleveland. Now lets talk about an L 88 style 427. Please
A 302 boss is a windsor block with large port heads. I am pretty sure the boss block was originaly cast for the tunnel port trams am racing effort. but if you want more examples of too new look at how many pages there are on a mid 80s boat only engine
If you have a true Boss 302, it is deserving of a close ratio toploader and 4.30 gears on a Detroit Locker equipped 9". But that's just me If you go C4, you'll run either A 157-tooth flexplate on a case-fill unit or a 164 tooth flexplate on a pan-fill trans. Both flexplates are 28 in-oz imbalance but they use different torque converters (flexplate bolt patterns are different). Late model 5.0 AOD stuff comes stock with 50 in-oz imbalance flex plates so you'll have to go aftermarket to get the 28 in-oz.
It's been touched on, but small block fords are externally balanced and you need to ensure that both the harmonic damper and flex plate/flywheel are matched to the engine.
Those 2.24" intake valves need a LOT of gear & carburation. Take that to the bank. The heads were one-off & re-vamped for a good reason. Joe
Well other than stock parts you are going to need one helluva loose torque converter. A real Boss doesn't start running until it hits 4K.
I have to agree.......the Boss 302 is going to be a dog with an automatic........Ford made them 4-speed only for a reason. Wish I still had mine!!!
C4 rebuildable cores are getting hard to find. I frequently see rebuilt C4s being sold on Craigslist, but I would not buy any transmission from an unknown source. You can use a C5, which has 26-spline input shaft, more clutches, deeper pan, and better hydraulic circuitry, but you will need a C4 bellhousing, valve body, torque converter, and servos. The C5 is just a C4/w lockup torque converter. Whether you use a C4 or C5, get a case-fill transmission, not pan-fill. Why? The pan-fill, although stronger because the bellhousing bolts to the case, not the pump, as with the case-fill, it is larger, and you might not have enough clearance for it, if it's going into a Mustang or other smaller car. Pan-filled transmissions were used in pickups and full-size cars. Get a 70-up transmission/w 26-spline input shaft. Make sure torque converter is also 26-spline. Stay away from early "Green Dot" transmissions and those with 5-bolt bellhousing (you'll need 6-bolt for your engine. 1970 Boss 302 engines has smaller intake valves than the 69 Boss's, which were too big. In their day, stock pistons had reputation for failing within 30,000 miles. If you're going drag racing, an automatic is preferred; it will shift faster and better than you can. Putting it behind a Boss 302 will be no problem with the right torque converter and rear gears. One last thing: If you have a real Boss 302 engine, it will be more valuable to someone who is restoring a Boss 302. You can sell it and then build the engine of your choice (within reason) with the proceeds.
Kind of odd the your heads carry a DOAE# and Boss 302 heads have either C9ZE or DOZE. Those are probably Boss 351 heads, which are also a fantastic cylinder head and would easily support 500+ hp. I'm not too sure but if I remember correctly you had to drill a couple holes in the head to use them on a 289-302, Boss 302 block, and the same on the block and use a 351 Cleveland head gasket. Your block should have either C8FE or DOZE casting #'s.
You can bolt a C-4 behind it but it needs to be race built....$$$$. I would try to hustle a baby C-6 for it. You can find them in small block truck and van applications. Correct bellhousing and shorter tailshaft. Joe
164 tooth flywheel, 28oz. balance, correct block plate and starter. All the c4's I'm aware of are 164 tooth flywheels.
