just getting around to replacing the 5.8 in my f150
doner is from a 96 f150 5.8
block is stripped except for what is needed but would like to degree the cam before removal to find out what it is and for practice as well.
i could not find a good how to for us first timers, i have a 95 5.8 cam as well as an 89 5.0 cam that i could practice with and see what specs i get...

so any help would be great.

and if a 302 can get 240ish hp then the 351 should have no problem achieving that right? not the 210 is says i have?

You need the cam spec'd sheet to degree it in.
You could reverse engineer it but then....   You wouldn't be asking "how to...." Lol

well i guess i need to do more studying.....ive never built a pushrod v8 in my life but built hundreds of other engines just not mine. lol, i build performance jet ski engines for a living but those are way different animals...i know setting my cam up for optimal performance is key....i know how to on the engines i build but don't know these old pushrod engines much. i have a slew of tools at my disposal at work where my engine sits on a stand and watched this video https://www.youtube.com/watch?v=p1w8OU_8-JM but wonder how much this is real world such as incoming air, fuel used, timing etc.... the numbers look great but prob too much for my stock tranny to hold. i just want to build a "better than stock" rebuild with the parts i have.

Set your engine up ready for cam degrading.

We will help instruct you through the entire process.

You MUST have true TDC and a movable pointer.

will do, putting new moly rings in mon or tues with crank seals, suprisingly this thing still has nice crosshatching and no worn  lip at the top like most. only one snapped bolt on the head so far......i'll post pics too. thanks

cam on left is out of the 5.8
cam on the right i was "told" was from an 89 5.0
sorry had to edit:
WHEN YOU ZOOM IN, cam on the left is from the engine......the lobes on the two (even though the alignment hole is facing on both the exact same direction) are way off from each other....

here are a couple more pics.......
i didn't realize these engines were so simple, all main caps are numbered with arrows
all pistons say front on one side
all rods are stamped with letters on one side so you cant mix them up
cam and crank pulleys only go one way and have alignment dots
for a 147k on this motor, still has really nice crosshatching and pistons show very little wear as well as the bearings. im impressed, i was expecting a lot worse.

If the 302 (5.0) cam is from a base engine, it will have a different firing order than a 351 (5.0) or HO 302.

yeah, i was told it was a roller 5.0 ho, but those lobes are way the hell off.....seen some twisted cams before that threw us for a loop on some jap stuff........don't think that happens much with these engines.

and if a custom grind cam is what i need.......no prob.........tell me what i need to run out of all this stuff and tell me a custom cam will suit this truck and its done........as long as you help me put it where it needs to be........cuz im confused on if you degree a cam and can't align it where you need cuz the chain is one link off....close with this link but not perfect....next link is too far off.....so what do you do?

anyway, i guess a custom non emission cam sounds kinda nice.......keep as much of the explosion in the combustion chamber to get as much low end torque......but not too long....incase i get in the mud and need rpm......

beers going down good.....lol

one link is a lot of degrees.

you need an adjustable timing set.  the budget friendly version lets you advance or retard that cam by using a crank gear with several key ways so you can move the cam events relative to the crank.

the expensive version is a belt drive with near infinite adjustability.  not needed for your application.

You may see this set offered by some places at a reduced price, but beware. This timing set can be had with different quality chains.
