7.3 CAMS ????

I have a question and I hope it does not sound to stupid! I have not seen that I recall information about cams! I know with gassers there is a lot of things going on with cams ! What I was wanting to know is there a "Hot" cam for a 7.3? or are there special profiles that dezeels must conform to ? Can a 7.3 benefit from such a "Hot" cam?

Yes. There are some cam options out there. The science for custom diesel cams is a bit different than gassers though...

Not much benefit until ya get to higher HP applications from what I understand.

Only one cam one the market that's a drop in and I don't think it's worth it.

For as a "hot" cam you have to butterfly the pistons

Is it fuel injection that takes lift and duration out of the picture? I guess what I mean about "Hot" cam is a better profile than stock!

Not worth the 525 for a cam unless you need to replace your can

Coming from a gasser world that had me confused too. On naturally aspirated and carbed engines only the cam controls timing and amount of air/fuel, but the PCM and injectors control all that in our nifty 7.3. Whatever the lift and duration is on the OEM cam in there, it's overcome by boosted air and squirted fuel.

I'm wishing for a
head for the 7.3. It's essentially HEUI valves instead of cams rods and rockers. If I win Powerball I promise to develop it.

Read a little of that link from Fordpride ! Looks like kind of a clearance limit on the the lift without doing some work on the pistons!Kind of answers why ya just can't drop in the cam without having to do more work on the engine!
