Crane 444232 Cam
I was looking at buying a new cam and headers for this summers build. The question i have is: Is there a cam that will give me more power from a SD system without sacrificing much reliability of this motor?
I still want the powerband to be from idle to 4000 or 1500 to 5000. I have never gotten anything higher out of her now, maybe 4300 in second gear with a C6 trans.
Vehicle:
1989 F250 Reg cab
351w w/c6
35000 orig miles
4x4

I have looked and have not found a cam that models significantly better, given the restrictions of SD.

I put one in my truck and havent looked back since. I would go for it even with crane in the state they are in. Just make sure everything looks good before you put it in, not a whole lot can go on. I havent noticed any problems since installation and my truck if anything is more reliable because i re-did some stuff while i was putting it in( hoses, injectors, timing chain, leaky gaskets.
lmk if you have any other questions or just search cam swap thread

I wouldn't go with that cam if I were you. In my opinion, it's too agressive for the SD system with it's 1/2" lift and tight lsa.
I had experience with crane cams on FI systems before and I found them not to be FI compatible even though they said.
I would stick with the comp cams. It's a milder cam and I believe it will work well with the SD system. Remember, these SD systems need a lot of vac at low rpm in order for proper fuel calibration. something I don't think you're gonna get with crane. It can cause you to throw a cel, engine damage, and/or eat your cat.
better to play it safe in my opinion

Salts you get the ThreadMiner award for today with this oldie from 2009!
Your '97 motor already has a decent roller cam in it so a flat tappet is considered a step backwords. Instead bolt on some 1.7 rockers and longtube headers for a solid boost across the board.

SD = Speed Density. The EFI system depends on a strong and steady manifold vacuum signal and pre-programmed tables to manage fuel and ignition.
MAF = Mass Air Flow. The EFI system utilizes a sensor to measure incoming air mass(volume) and uses that and pre-programmed tables to manage fuel and ignition.
MAF is the superior system because the computer has real time input on airflow through the motor so it can better adapt to environmental conditions and modifications without any additional programming.
