OK, so I have another opportunity to acquire a roller out of a Mustang GT with less than 100k miles on it and it has all the stuff still on it i.e. power steering pump, AC compressor and the full serpentine belt and all pulley's. Will this motor drop into the 73 Mav and everything fit, it would be so nice to have one belt driving all the accessories or is there a gremlin in the mix?
I don't recall if there is an issue with the rear-sump oil pan on the 5.0L motors. Also, check fan- to-radiator clearance and if you're planning on sticking with the EFI, check the upper intake-to-hood clearance, as well. Everything else ought to work out. Eric
Oh, yeah... forgot about that. Good catch. You need a 28 oz. flexplate if you're keeping the C-4, or, a 50 oz. if you're going AOD. Also, make sure the converter bolt-hole spacing and flexplate tooth-count sync up with your application, too. Eric
You will need the 50oz. flexplate regardless of the trans your using. A 28oz. used on the 5.0 will create an imbalance.
Ok Thanks for info, I will be tossing the fuel injection and putting my heads, intake and carb on it, also planning on tossing fan blade and running flush electric fans on a new aluminum rad, so sounds like this will work, man this will save alot of work and exspense......thanks again
You may need to change the timing cover and add a fuel pump drive to the cam? Fuelie motor wouldn't have either of those items. Somebody else will be able to confirm this if it's an issue. Also, if you do have to change the timing cover, water pump rotation/cover compatibility may be an issue. SPark
The 5.0 blocks are also missing the boss for column shift linkage. If you run an electric pump and floor shifter these won't be a problem.
break it down to a...long block...and start from there. 100K is a little much to just cam and new heads...JMO
If you're running a C4 with 157 tooth flexplate, the 50 oz required will be a custom piece(still readily avail), no factory combo used this... Also you'll need a steel gear for the cam, non roller engines use iron gear that may last 10K mi...
Changing over to a front sump pan, you also need the matching oil pump pick up that goes to the bottom of the sump
Yep OH we are still going to do a total rebuild, machine work, bearings, all of it. I just wanted to make sure it would run with the serpentine set up turning everything plus it comes with the AC compressor and the oil pan and flex plate is no prob, the whole works will be balanced at machine shop. I didn't mean to imply I was going to just toss this motor in "as is" lol
Not if you install a 28 oz. damper up front use a pre-'82 302 crank machined to fit the 5.0L. Was, like, $100 back in the day. I've done this to a 5.0L carb conversion where I just kept the roller block and retro-fitted a carb set-up backed by a C-4. This was before the retro-fit roller kits were available. Eric
You can get a timing chain cover with the hole for fuel pump and cam eccentric for pump that works with both reg and rev. Water pumps from jegs or summit.they will also have the oil pan and also the 50 oz flexplate its not a custom piece. I had the same setup in my 77comet.I also ran a composit gear on dis.then you don't have to worry about gear chewing up the cam
