A guy on a local classifieds site has a 302 h.o. out of a 91 cougar and i was wanting the h.o.cam for my 302 i installed in my 79 cougar a couple weeks ago,,so my question is ,,is that a roller cam or will it work in my motor??? thanks
All passenger car 5.0/302 from '86-up are roller... Those cams will not work in a std lifter block...
If whatever this said cam is, whatever the cirspoogestances, IS indeed the stock cam from an 80s 5.0 HO, if it is pre-1985, it is not a roller cam, if it is 1985 or newer, it is roller.
it can be done. to drill the lifter valley and make it a roller block as long as you have all of the required parts to do so.
But you still won't have the proper support for the LONGER roller lifters...
Aftermarket cams for std blocks, have a smaller diameter base circle than the factory cams...
he says its not a roller,,it was carbed
Then it is not a factory 302 HO so you have no way of knowing what cam is in the engine ;)
he said a new cam was put in last year,,he only wants 100 for the whole engine intake to oil pan ,,and it runs but all i want is the cam,,hes hurtin for money pretty bad
Weren't the 85 Mustang 5.0 rollers? You do realize someone could have carbed a 5.0 HO right?
Yes I know but no 91 Cougar ever came factory equiped with a carbed 5.0 HO;)
If he really wants to make the sale, tell him you want to yank a valve cover and measure a push-rod. That'll tell you if it's a roller cam or not.
Flat tappet 302 push-rods are approximately 6.875" long, while factory roller push-rods are 6.200"...if the engine has an aftermarket roller lifter conversion, they'll be about 6.400" long.
Good luck,
Don
Good advice Don...
Thanks buddy, a good idea smacks me across the face every now and again...lol.
91-93 cats and birds with the 5.0 supposedly use the 93 cobra spec cam.
There are a few 87-88 5.0 Cougarbirds HERE that are carbed.....Just because something's on a used car when you got it doesn't make it stock ;)
As stated above; ask him what the pushrod length is.

The Cobra cam has a 1993 part #. It WAS used in 93 Cougars/Tbirds, but with 1.6 ratio rockers as opposed to the 1.7 ratio rockers in the Mustang Cobra. '91 & '92 model year Cougars & Tbirds 5.0 cars used the H.O. cam.
Oh I know. The point I was trying to make is that the original poster has no way of knowing what cam he's getting (flat or roller, which ever is in the engine) because it's not a factory engine. Any after market cam or factory cam could be in it. I guess I didn't word that clear enough. My fault :o
turns out it was a roller,,the guy didnt have a clue what he was talkin aout
