Here we go again folks. I promise my video making skills will get better LOL! Anyways 10 min video about what I know about fox body camshafts and some tricks to know when pulling these engines apart or even identifying the parts you currently have, find or see on the net or at swap meets etc.

Thank you for covering this.
Thanks for the vid, I bought my 5.0 in 1999 and was told it had been cammed, always believed it because it loped like crazy. Just sent the block to get machined and was trying to figure out what cam I pulled out, googling ZE cam brought me here, welp ok then
another good video!
Great Video and thanks for sharing your knowledge on our beloved Foxes! After owning these cars for 24 years I keep learning and the info you give us Fantastic!!
Actually my man you even though you zero’ed at the base circle first, for rookies just make sure you explain the difference of the base circle measurement and the lift measurement. You said 1.32” but if you look at your video it was actually 0.320” lift, so your difference between base circle and max lift was 0.320”.
You then multiply 0.320” max lift by 1.6 rocker ratio to get your true valve opening measurement of 0.512” max lift. The same for the second lobe you measured and you said it correctly as 0.274”, then multiply by 1.6 rocker ratio to get that valves true opening measurement of 0.438”.
A machine shop isn’t going to get a better number than your calipers, the best way to measure a cams lift on intake or exhaust without decreeing the cam in the block is to use a micrometer. But, your usage of digital calipers is good too, don’t downgrade your knowledge bro, your close enough for government work.
Remember guys, for the rookies out there don’t forget its the difference between base circle and max lift of the lobe, then multiply max lift times the rocker ratio to get your true valve opening measurement. Camshaft lobe centerline angle can only be measured in the block by decreeing the cam, find intake lobe centerline then exhaust lobe centerline and the difference between those in degrees of crank rotation is your lobe separation angle.
Valve duration measurements are taken using a dial indicator at 0.050” after valve starts to open & 0.050” before the valve closes in crank degrees. Lobe centerline is measured in crank degrees while using a dial indicator at 0.050” before max lift measured to when the dial indicator stops moving and to 0.050” after max lift then add those two numbers of crank degrees together and divide by 2 for lobe centerline measurement. Lobe separation angle is the difference in intake & exhaust lobe centerline’s measured in crank degrees and overlap the amount of time both valves are open also measured in crank degrees.
Great video always looking forward to seeing your videos always learning something thank you for your knowledge!
Good info, keep it up man!
Good stuff glad I hit the magic button!!
Excellent info Dan! Thanks for the knowledge and the videos! I plan on using my stock motor in my 91 and going on3 with 1.7 rockers factory cam also! Keep the videos coming!
Thanks for your vids bro, i learn a lot from them, can't say i understand everything but thats not your fault;)
Thanks for watching
Great video knowledge is key I was wondering what cam I had in my 90 Fox LX stick shift I was running some numbers on the back and was coming up with nothing just like you said LOL now I know where to look
berry helpful video neo
What's your opinion on advancing the cam timeline to make the power and torque come on at a slightly lower rpm. I hear engines that make good torque down low spool the turbo faster and o feel like of u degree the cam n to bring the power n lower u get n the boost sooner like faster spool up down low.
I wouldn’t do any of that. Really.
It’s ok just keep up the rambling. Where’s my Neo Mustang winter hat lol
if iam not mistaken the 302 is the worst block for boost, anything over like 10lbs the block will split right at the cam tunnel or the mains I think, iam not sure.
Jason Gordon lol ok sure
WRONG. Neomustangs can teach you that
No, revving it to 7000rpm @ 15lbs will brake it.
Hence his reasoning for running a stock cam theres nothing to be gained by swapping the cam and shifting the power band up to 7k that 30to50 hp ain't worth splitting the block
Even if you did it won’t be 30-50
So....what benefits do you gain, by adding a 1.7 Cobra RR to a stock bottom cam?
1.73 rockers changes the ratio of the cam lift. Stock cam .444 is that lift w/ stock rockers. You put 1.73 ratio on the .444 cam shaft it puts the total lift in the .480 range. Like a B cam.
@@Neomustangs thanks for the reply. My mustang has the 1.7 RR's on it...it has stock heads and cam. I have always suspected it "was" boosted in it's former life. Just never understood "why" someone would put those in without upgrading the other things. It is an 87, so, I know it would need a MAF conversion to go heads and cam. Just didn't know how beneficial it would be just changing the RR's.
Sorry for the novel 😅
@@jpp9846 must be a speed density system. You cant change the cam on a speed density HOWEVER you can put GT40 heads, intake and 1.7+ ratio rockers and cheat the design to get more out of speed density. We did this and run 13.0's with my dads speed density system for years. Full interior full weight.
Thoughts on the anderson n41 cam
Its not a bad cam. What are you plans with the car?
@@Neomustangs street car most likely its got tfs 170 heads with the tfs street burner intake 30# injectors and a bunch of other stuff .
I got a stock bottom end with TFS2 top end kit and planning on running on3 kit but scared to crack my block in half. Any ideas or suggestions. Just a fun street car. Don't plan on really running it at the track.
Nothing wrong with that. You can have a very mild and safe tune. That's a stout top end kit for a stock block car, with min boost around 8lbs on pump gas and 15-16 degrees you would be fine.
@@Neomustangs appreciate the reply brother.
I’m a firm believe in keeping the rpms low on the stock blocks with boost. It is going to be hard with the stage 2. I run a stage 1 which runs to 5500. I currently 12-14lbs to 5500.
Bryan Michalski yep. I kept mine in all these videos under 6400 with 351. And my rev limit was 6200 on my 302s.
Thanks for all the info
Huge mistake! I pulled a new Crane out of the box, installed it without matching the cam markings to the cam card, checked for safe lift with clay. Someone got the wrong cam into that box. It even had the wrong firing order! I could not figure out why it wouldn't start using the firing order on the cam card. What a mess!
