I'm converting .842 and .904 dia. hyd. lifters to mech.(internal sleeve). I like the "deep skirt" design, provided by powdered metal tech. They are also cheap compared to aftermarket. I don't know how much cam they can stand, but I like all that skirt to pick-up side loads. Thoughts ? roverman.

Hey Paul
I have an Edelbrock #3722 roller cam for the 5.0 ford that I can measure up for you if you like. It advertises at 282/282, 220/220 @ 0.050, 0.311/0.311 lift @cam, 110/110 lobe centers. It's the biggest stock EFI cam that they have.
Regarding rev kits. Unless your running some wierd old monster cam, rev kits are pretty old tech. They were invented to control lifter float back when cams were made by eye on a foot powered grinding stone. (stop laughing I have an old HD performance manual that has a picture of just that!) Valve spring and cam lobe profiles have developed far beyond the need for a rev kit. While they do reduce the load that the valve spring sees, they dramatically increase the valvetrain mass causing even more stress on a weak lifter setup such as ours. A better aproach to me is a short lobe roller with a longer ratio rocker. The spring can control the valve just fine, i'ts the push rod and lifter that cause all the trouble. This gives the spring more mechanical advantage to control the roller and removes stress from the lifter valley. I,ve done that lifter valley brace and it works well. Just get all your machining done after you install it and never undo it again.
Cheers
Fred

Can we get this going ? Forget the rev kit, plate and rod idea is merely to retain the dogbones, instead of hacking together (2) V6 "spyders". roverman.

Hey, sorry for not being around. My personal life is in chaos. The upside? I get to park my motorcycle in the living room and no one's going to squawk. I'm dragging the Olds engine into the dining room for some if its work. I get to do that now if I want.

Fred, if you're still around, I'd love to get the cam profiled. I need the ramp rates of a cam, any cam, before I can get one ground.

No problem Paul.
How much resolution do you want? Every 2' or 5' or....?
Sorry to hear about all the turmoil, but the Olds in the dinning room is pretty cool.

Remember, A positive attitude may not get you everything that you want in life.....but it will piss off enough people to make the effort worthwhile.

I went thru a time, many years ago, when I got to split the case on my RM 250 motocross bike in the kitchen. The whole apartment reeked for weeks.

Hang in there, Paul!

Fred, I don't have an intelligent answer to your question, but let's start with the 5^. Seems easier.

Thanks for the kind words. Life is an adventure and I'm not going to complain.

My Kawasaki 500 probably needs new crank seals, so I get to do that inside where it's nice and cool.

Guy's, the more good news is, practically "any" kind of auto oil/solvent, will squelch the squawking and those pesky fish odors, from the kitchen. I alway thought a, non salvageable 215 would make a nice, glass table base. lol. Hey Paul, I'd rather send you the cams, when their done. What say Buddee ? roverman.

Hey Paul,
Sorry for the wait. I dug out the cam and found my degree rig hiding under my dusty golf clubs. Monday the dishwasher quit (the mechanical one) and the A/C spit water all over the basment last night. Now I,m told that the Rangie doesn't sound right and I think I see the blower belt hanging from the lower control arm.
I might be just a wee bit longer.
Cheers
Fred

Fred, You don't suppose, if you had a "real" Rover V8 in "Rangie", she mite be less problematic ? Can't we just do the job "Au Natural" ? lol. roverman.

Art, the only problem is "The Lovely Lynne" has a finely honed maternal instinct and a right foot like a brick. As long as her Rangie (465hp) is faster than our daughters (440hp) then family harmony prevails and the world continues to turn nicely.
Last spring I put some 24x10 and 12 wheels on the truck and "The Lovely Lynne" said "they look sweet but the rangie is slower now. Give them to Megan (choke)and slow her down some. Can't you do that pulley thing some more?" We now have 22's on the truck with a new fuel program and I'm off the sofa.

Jeepers, crazy web browser wouldn't let me post a reply until I hit the (refresh) key sequence, even though I was logged in. Anyway,

Fred, I'm clearing my plate and I'll be ready to devote some more time to this project soon. I'll be grateful to hear what you're able to come up with.

The motorcycle's in the dining room and I'll be dragging the Olds engine in there soon.

Paul and Fred, I was hoping someone would be bold enough to fit an Old 215 into a mortorcycle. To be dragging an Olds, sounds like fun ! roverman.

Art, I've seen the little flathead Ford engine in a bike frame. Kind of a scary lash-up.

The Buick/Olds 215 makes slightly more sense. But not much more - it's still a pretty long engine. It might make sense in a trike. Bolt it onto a Volkswagen transaxle and attach a springer front end. Wheelies.

Y'all do know it's been done in a monocycle configuration?

Oops, the motorcycle has been done, as well:

Paul, I gave up on the repairs and took the Lovely Lynne to Spain for a few weeks. Now we're back, heres your cam specs.
The base circle is 1.360" lobe separation is 110' and intake centerline is 110' both lobes measure out exactly the same @
0' -0.000"
5' -0.002"
10' -0.010"
15' -0.027"
20' -0.050"
25' -0.080"
30' -0.115"
35' -0.150"
40' -0.186"
45' -0.215"
50' -0.244"
55' -0.267"
60' -0.285"
65' -0.296"
70' -0.305"
75' -0.310"
80' -0.310"
85' -0.305"
90' -0.292"
95' -0.274"
100' -0.248"
105' -0.215"
110' -0.175"
115' -0.133"
120' -0.099"
125' -0.065"
130' -0.044"
135' -0.028"
140' -0.015"
145' -0.009"
150' -0.000"

These are in camshaft degrees not crank degrees
This is intended for a hydraulic roller and 1.6 ratio rockers.
hope thats useful for you.
Cheers
Fred

Hey Art, roller dia. is pretty standard for all the american v8's @ 0.700" The Ford lifter body is 0.875". For those of us on "roller quest"
the dogbone dimensions look to be the same between Buick Chev and Ford.
Cheers
Fred
