Hi guys, I'm new to the forum but I've learned alot from here and finally decided to join..I bought this 5.0 to put in my 68 but I'm trying to figure out what I have to do to it to hook it up to my c4 and put the accesories (water pump, alternator, distributor etc) from the old 289 on it..the guy I bought it from didnt know much about it as he was going to put it in his comet but went another route..So far I know I need to change the oil pan, not sure if its a roller or not so I might have to get a different distributor? ..I attached a picture of the block castings..I believe its an E5 but not sure if its a roller...thanks in advance

It's a pretty straight forward swap. Here's my GT40P swap. Unfortunately due to a "forum" upgrade, some of the pictures were lost and we're limited with our editing. Anyway even without some of the pictures, you'll understand

Got my GT40P up and running in my 66

I waited until I had it up and running with the bugs worked out before posting so if anyone is planning on doing it, they'll have all my info ready to go and not waiting on me. Sorry for the poor cell phone quality, it's mostly to show it actually running. It's taken me a while mostly because...

Thanks man!..so basically I need a 50 oz flexplate, rear sump oil pan, and a newer distributor ...If I go to autozone and buy a distributor for a 1985 5.0 it will work wether mine has a roller cam or flat tappet? (Still not sure which one it is)

That's it. Get a 50 oz swap C4 flex plate. Probably the quickest and easiest way of finding out if you have a roller cam is to pull a pushrod out and measure it. Honestly I do not know the length but they are shorter then the flat tappet pushrod. You'll have to find out how long the either pushrod is. Sorry I can't be of more help on that.

If roller cam, 85 Mustang 5.0 5 spd, not automatic as the automatic 5.0 used a flat tappet motor

I Read a tip on the 5.0 heyday (when mechanics were replacing HO cams & trying to get them to run on 302W firing order) that Carbed 5.0's ran Roller Cams & Injected 5.0's Flat Tappets OR Visa-versa...

Someone else will know for sure.

Thanks guys, I guess i'll measure the push rods because I don't know if it was originally carb or efi and I don't know if it came from a 5 speed or auto either..Or is there a way to tell from the block castings?

Only for the 85 Mustang. The 5 speed had a 4V carburator and roller cam. The automatic version for the Mustang had a flat tappet cam and a throttle body EFI. The 5 speed Mustang 5.0 was the only model that had a roller cam in 85. In 86 both 5 speed and automatic Mustang had a roller cam. 87 or 88 was where the 5.0 received a roller cam for cars.

Nope. Both used the same block. Your E5AE block is a "roller cam" block with the provisions for roller lifter dogbones and spider.
