302 conversion help PLEASE
Hey guys been a long time since I posted....anyway I have a 1967 bronco well it doesnt look to broncoish but of well. Theres no body no original sheetmetal or anything just a mess of tubing and some seats. What I am thinking is to rip all the crap ive put on it (roll bar, makshift body, staight six/tranny) and biuld a trail/mud rig. I want to put a 302 in it if possible. I can get a fuel "infected" 302 out of I think its a town car or somthing for 100 bucks that runs mint. This rig will be a VERY low cost project to clarify. Some of my questions are, besides the intake/carb what else do I need to switch out to run a naturally aspirated engine? I have a 4sp tranny that is a spare for my 73 with a 360 and is there and way I can throw that behind the 302 I dont know if it bolts right up or what. Thats all I think of right now but thanx for any help.

That tranny won't bolt up. You might be able to switch bellhousings though. you would stiil need to get a clutch-flywheel combo that would work.
Here most of the things you will need to convert to a carb.
intake, carb, electric fuel pump, distributor, igniton- points or electronic, Relays for the pump and distributor. fuel pump shut off- incase of an accident.
The relays and the shut off I got off a '90 Crown Vic. at a junkyard for 10 bucks. Shut off is in the trink on the driver's side. There's a set of 3 relays under the hood on the driver's side in a plastic box.
If the town car the motor is old enough it might be TBI. You could luck out and find a carb that fits.
Good luck

Ok let me see...I have a stock 4bbl manifold, and a dist. off a 289. To make it a mech. fuel pump I need a cam from somthing that had a mech pump right, if so then Ive got a 289 cam but I dont know if they are the same. I forgot to say Id need a bellhousing and clutch but to anyones knowledge is there a bellhousing that will allow the 4sp to bolt up?

The cam will fit.
For the bell housing and clutch you need to know what model 4 speed it is to be sure. For the tranny part you might have better luck posting this over at classicbroncos.com

You can't use a 289 cam in the block because the base circle is too large.
You don't need the cam you need the drive eccentric for a mechanical fuel pump and a timing cover with a boss for a mechanical fuel pump. You will take the timing cover off, remove the bolt from the cam drive sprocket, place the eccentric on the bolt and then re-install the bolt.
If you have a boss for a fuel pump on you timing cover you can re-use it, if not you need a new timing cover.
If you use the 289 distriutor you will need a hardened gear installed on the bottom to use with the roller cam or the cam will shred the distributor gear.
