cam problem
Well i got my motor out today and discovered something. It turns out that i have a 1993 motor and it has roller lifters. well i already bought a non roller cam and lifters. so what should i do, use the cam and lifters i bought or get a roller cam to go with the factory roller lifters?

I would buy a new roller cam and of course new roller lifters to match (I'm sure you're aware that you cannot re-use lifters with a new cam). Why not take advantage of the benefits that a roller cam setup provides, especially since that's your baseline setup? No use going backwards in performance and efficiency. Just my .02. Out of curiosity, do you have mass air or speed density? If you have the latter, I don't know if your computer is going to tolerate anything too wild and crazy. If you have the former, you have the liberty to go with a considerably more agressive cam, but of course it all depends on how you want your truck to run. Good luck!

Thats what im thinking, i dont want to use 1950s technology. But you can re-use roller lifters, they dont get into a pattern like flat tappets do. and I do have speed density, thats what im concerned about, whether or not this crane cam is going to be too much. it looks like my only option though if i want to stick with the rollers, other than a custom cam.

look at a stock mustang GT cam. the numbers are better than the crane (if its the one I am thinking of used by some "L" owners) and it will work with SD since the cam was/ had been used mostly unchanged from the days of mustang SD. A bud used my stock cam in his 94 "L" and it picked up quit a bit, not to mention I gave him it for free, I then bought the Bronco and bought a 92 GT cam for $20, not a bad price as that is the going rate. You can reuse the rollor lifters as since they do not wear to the cam.

found this on cranes website:
"Many magazine articles, and a few books, have stated that “Speed Density” type EFI systems on 5.0L Fords must be converted “Mass Airflow Systems” to work well with aftermarket performance cams. This conversion is expensive, but has been necessary because of the idle and off-idle vacuum characteristics of many performance cam profiles. Crane Cams currently offers two excellent camshafts for street performance that work very well with stock “Speed Density” systems in cars and trucks. Part #444212 is a hydraulic roller camshaft spring and retainer kit that reuses the stock hydraulic roller lifters and the 5.0L HO/351W firing order. Part #364211 is a hydraulic roller camshaft using the 302 firing order. It also reuses the stock hydraulic roller lifters. Spring and retainer kit 44308-1 is available to replace the stock springs and retainers. While compatible with the stock computers, both of these cam kits respond well with computer upgrades. They also are compatible with stock torque converters on the AOD transmissions.

I had my heads mildly ported when I built my engine, didn't know about the "air boss" at the time. I assume they removed it. Got me wantin to pull a header and look in there and see for myself
