So wouldn't you know it...I head to the other junkyard in town and find a 95 GT with a 5.0 HO that still had the engine intact...not an easy find these days. Someone even had it half dismantled to get the fuel rails and injectors....needless to say I removed the cam which BTW i'm getting pretty good at now
The lobes measured good with .275 to .280 lifts according to my caliper.
Now I am somewhat committed to this project and it just got a lot cheaper if i can use this cam etc. After sifting through the data I am thinking the 95 specs I found are very similar to the 80's HO cams but a dual pattern...perhaps too much cam for my application...not sure ?
91-95 HO:
Lift: .278 intake, .278 exhaust
Duration: 276 intake, 266 exhaust
Overlap: 39 degrees, 19.51 factor
Lobe Center: 116 intake, 115 exhaust
Ford P/N: F1ZE-AA (91-94) F4ZE-EA (95)
I will measure the PTV clearance when the time comes. Total lift should be around .444 with the stock rockers so from what I gather from xctasy's info it should probably be fine.
I do have the original 1980 255 sitting on an engine stand...perhaps I could use it to mock up the cam and check clearances or is it different enough compared to a 302 that wouldn't work ?
The only other question is should I get some better valve springs. I don't really know...any suggestions ?
