Have a 91' V8 ranger. Unfortunately I just burned a bearing and rathe than rebuild the motor going to pick up another from the junkyard I been eyeing up. It's a 5.0L HO from a 91 mustang. My ranger is set up for a carbureted V8. Will I be ruining this HO motor by putting my carb setup on it?

Nope, just make sure you have the right gear on your distributor and you should be good to go. :icon_thumby:

Could you elaborate? I've got a 5.0 that was given to me and I'm thinking if I decide to use it I'll just switch to a carb for simplicity. Thanks

Non roller block engines need to have a cast iron gear on the dizzy while roller block engines need a steel gear.

Also not all roller block 302s are HO and HO engines have a different firing order then non HO 302s.

The flat tappet cams use a cast iron gear and the roller cams use a steel gear.

Going to use the same intake, carb, distributor setup I'm running now but it's got a Cast iron gear. Is it east to replace with the steel gear or do I have to get a new distributor?

You cant put a steel gear on a dizzy with cast iron and vise versa. But I have heard that you can put a brass gear in place of either and be good but not sure on the life of a brass gear.

In the end, it would be easier to get a new dizzy.

Heres a link to the one that I will be using. They say it has the steel gear for the HO engines. Also it is an HEI unit too. I wanted to keep it simple and whatnot plus had a guy that I know say that he has been using it for 2 years now without any problems.

Plus was also told these units can have the brass gears put on them too.

You need the distributor gear, or a distributor your choice, from a 1986 Mustang GT 5.0L Carbed, manual transmission............ only choice for a stock gear/distributor that I know of.
I could have got the gear for @$75 a whole new distributor was @$95. I figured it was worth the $20 to avoid swapping the gears :)

A brass gear will not last as long as steel, obviously they are quite a bit softer.

If you are getting a different dizzy go ahead and get a steel gear. It was a $20 difference for me too, I just got a rebuilt dizzy.

Hey guys, can you fit an HEI dizzy under there? My buddy is using one of these in a 91 5.0 HO, but he has a 49 Ford, so it has more hood clearance.



Anyway, this dizzy is really nice. The coil is in the cap (HEI), and you only hook up 2 or 3 wires. He bought it from this guy on Ebay:

Should be able to, I don't much care for the looks of them though. :dntknw:
