Heath's cam

Sounds like you had fun. If you get down this way again let me know. If I get up your way I'd like to stop in and meet you.
I'll be in southern Ut this sept at one of the NP's camping for a week maybe we can get a TTS get together at he same time?
(now way off topic!! Sorry!!)

Like Paul just mentioned, try to time it to be at Bonneville. But a TTS get together would be fun also.

As Paul also mentioned, there was an issue with valve to piston clearance, with the 1st design towing cam. With my 'new' heads I had to have just .002 taken off the valve stem when I had to have the valve seats set in the same amount. The new design doesn't require and valve to piston modification.
 
GTG at my house would work. Orionthade and Jamin6.5 are just across the water and Raleigh and I still need to meet. I'm closer to Zion and Brice NPs than going all the way to Bonneville.
And we could talk about cams (still trying to keep thread kinda on topic)
 
What is different with the Springs in heaths cam kit? What would be similar from say procomp?

Pro comp 910's are what ford idis use for an upgrade. I am trying to compare the price of putting your own kit together w/ a regrind of my own to a Heath kit and decide if heaths is worth the $$$. I am more interested in the Performance cam with my current engine a $700 is hard to swallow (costs more than the truck its going in)

Rode in Turbine Doc's pickup quite a few months ago, in Slidell, La, on my way back to Vegas after delivering the chassis to Conroe, Texas, and that beast did really haul the mail. No lag with his big A Team turbo. Met up with Tim and Pepperidge.

Good to see you around! I was wondering how you've been...

quick question: What was that country you said your brother moved to again?

If you are talking about my brother-in-law, it is Jalisco, Mexico. I'm moving to southern Arizona!

You guys talkin' all about these GTGs makes me want to say you should be doing a cam comparison here in Sandwich as a stopping off interim test... You know for between where ya'll are coming from and ya'll are going to.:hihi:
See Paul, I'm talkin' CAMS here. :D
 
OK why stop now :hihi: Maybe a mod can clean up the thread? Start a new one?

Paul I'll look at the link you posted next, What are the best two days to be there? To see races there is on my "before I die list". I probably could only swing two days as Im meeting family in S Utah. We'll be in the Moab/Caynonlands/Natural bridges area.

6.5 diesels won't run without a camshaft.

I would like to see some true dyno numbers of both Heath cams to see if they are anywhere near his claims

Would you like to see just the engine on a dyno stand or a specific vehicle on a chassis dyno? Would it be a water type dyno or an electric brake type dyno? Who would be operating the dyno? Would it be at a big dyno day where every vehicle would use the same setup? Or where it would be just set for one vehicle? I had a chance for a big dyno run a few years ago, the dyno would of been free, instead of the $110 an hour, and would of taken the whole day to do a proper test.

But the whole process didn't take place because of quite a few major malfunctions with my other engine.

Vehicle weight, aerodynamics, and speed attained over a measured distance has been used for many years to establish a certain amount of horsepower. It hasn't changed any over the years.

Elevation also makes a big difference in horsepower.

The Towing cam and Performance cam are billed as requiring cam specific tunes so that's got to be factored in or out. Then there's the turbos....
I concure with 635 with the added comments:
Seems you'd almost have to do the runs using the same motor with only the cams as the difference and then test it out of the truck and now its the RWHP vs Flywheel thing. It would be interesting though but, who's going to buy both cams:???:

To run my 6.2 motor and HP cam against 635's 6.2 and HT cam would seem even more suspect. His 4:10s vs my 3:73s, his tires against mine, injectors, turbo's, driver techniques, dyno equipment, locations, altitudes, air temps, extrude honing and don't forget the added HP from the chrome...:D. Yeah, most of those things are supposed to be able to be nulled by the dyno programs but even the programs are different...you might as well try to get "true numbers" out of climate scientists.

As for being anywhere near the claims, "This combo delivers maximum power and torque...Details of engine and transmission tune discussed with customer prior to programming." Not much to go agains other than owner testimony which we're getting input on here.

Tanman, the springs are new but not OEM to better to keep up with changed dynamics of the cam andvalve coupled with the RPM increases attainable. Sorry, I don't know the makes or source.

SQUIRREL!

:hello:Coming from Texas, Washington and Utah and swinging by Sandwich IL 'as a stopping off interim' to discuss cams while heading to Bonneville is a great idea…no wait!:rolleyes5:
 
I enjoyed the conversations with Bill, really good guy.. He did make some big number claims with his cams in "their" trucks and even with a stock turbo... I would just like to see those numbers backed up by a RWHP dyno.. Is all that I'm getting at.

Yeah, even with all the variables, it's hard not to wonder. I already plan to run mine for the heck of it, but I'm afraid it's only going to be relevant on a very narrow scale.

The only correct way to do this would be have a good running 'stock' engine and go to a specific chassis dyno and spend money for a few runs. Make sure all the parts are in perfect working order, what isn't perfect spend the money to get them that way. Then take the engine apart and install the camshaft. Go back to the same chassis dyno and spend more money for a few runs. I am sure there are chassis dyno's on the east coast, and the mid-west that would work for you guys. Then you could try the different turbos to get your needed horsepower numbers!

Or buy the cam, install it, and enjoy your new power!
