Just for kicks, I contacted Jones. 2 hours later they emailed me a cam recomendation. A lot different then I would have chosen but I trust their expertise! He explained why he recommended these timing events and lift values. Seems very knowlegable and took the time to explain my concerns. They're also $100 less then bullet. They use Johnson lifters. I'm assuming they're probably high quiality. Only concern I had was the very short duration at .050. 204 and 208. But hey, he's the expert so I'm sure he has his reasons. Also had less lift on the exh but he explained why in detail. Very pleased so far and Il probably be going with him

Mike Jones is a super good dude. And a damn great cam grinder. Used probably 35-40 of his cams. I wouldn't be afraid of any grind HE picked.
I think the biggest single factor in getting the right cam is getting with a guy you can deal with. Like Racer Brown, when you call Jones cams you are talking to Mike.
Keep us posted.
I gotta say I was surprised at the 204 and 208 duration at 050 he recommended but I'm sure he knows what he's talking about. I figured its want more with 2.02 ported 360 heads. Air Gap rpm and headers but Il take his word for it. Was hoping to have a little cammy sound but as long as it pulls to 5500 I'm happy
That is a common misconception. Ported heads done right will make a small cam rpm like a bigger cam would with unported heads. The bigger cam with ported heads just pushes the rpm range higher, but usually at the expense of low speed characteristics. I tend to go small on cams, and the Jones recommendation is a touch smaller than I would have thought, but I don't know the whole combo either.

I'd almost bet if you looked at the seat to seat numbers verses the at .050 numbers verses the at .200 numbers you'd be surprised. I'd bet it's about 6-8 degrees bigger by the time it gets to the at .050 number. He likes fast ramps. It may not act as small as you'd think RPM wise.
I can give you the combo quick u f youd wanna give me an idea what youd change. I m fine with the moderate valve lift, but the duration seems a lot shorter then I would of imagined,but I was gonna tell a guy that does this for a living that he was wrong
It's a std bore and stroke 360la. Indy remain heads with 2.02 not valves and .509" springs. Spent a lot of time hand blending the bowls, gasket matching and smoothing everything up. It came out to 8.3:1 with the gaskets I used. Roller chain, hv oil pump, electronic ignition. Headman headers, which for the money are the best I've ever used, and 2 1/2" exh. Currently running a Summit cam which is an Edelbrockperformer knock off and is very disappointing. Started with a cast iron 73 340 intake, now a Torker 340 and a Qft Slayer 600. Gave up some low end with the intake change but the intake was a free piece that was still new. After 2500 it pulls like crazy. I'm going to an Rpm Air Gap and wanting a cam to compliment it and pull to 5000 or 5500. I need vacuum for power brakes but I can always put a resivoir on if need be. Its a 5000lb truck, 4.10 gears and auto. Mostly used for off roading, street stock mud drags and some street driving. Fuel mileage and idle quality aren't major issues. If I need to pull stumps, I've always got Low lock.lol Running stock rockers and comp push rods for now. So you think the short 204 208 duration will provide plenty of grunt up into the 5000 rpm range in your opinion?
After seeing the combo, I think the Jones recommendation is a good one. I have a customer who shifts at 6000 with basically the same combo, with the exception of 8.8:1 CR, and a 218 @.050" cam. It's also a shelf grind, so a smaller custom would probably work just as well for him, if not better.
BTW, the Edelbrock cams are nothing but Melling cams with an Edelbrock part number. They are old and slow lobes. You would be surprised how many companies rebox those cams, including Summit. I carry those cams in a different brand as a low budget option, but they're certainly nothing to set the world on fire.
YR, I hear ya. I wish every cam included the .200" numbers, 'cause I like fast ramps too.
Yeah I've found at least 5 different brands with identical Edelbrock specs. Not impressed at all. It'll spin to 5500 but it's not pulling and seems dead at 4500. Low end is not what I expected from a "torque" cam either. So you think the Jones 28th that shorter duration will pull to 5000 just fine? Thanks a lot for your input. I trust his judgement but a second opinion is even more helpful
It should easily pull to 5000. It's all about how efficiently the cylinder is filling, not so much about how big the number is. With the fairly low CR, a smaller cam with a good lobe will help cylinder volumetric efficiency at lower rpms where you need torque for a heavy truck.
The 5000 lbs, the truck, the mud, and stump pulling is what I see the drive behind the recommended cam. You can turn 5000 rpm's with a stock 318 2bbl cam and stock 318 heads. You will have more cam, and better flowing heads. Pulling to 5000 rpm's won't be a problem.
I'm not so concerned with the idle rpm to 2500. When I'm in the mud,i need the power to spin that motor and tires harder then the cheesy Edelbrock knock off cam does. ITl spin over 5 but makes no power. Like I said, if I need tons of low speed grunt, I pull the transfer case into low. Bout like a D9 car then
But that won't change the fact that the weight and use of the vehicle will be heavily considered when a cam grinder chooses a cam.
Trust me, if you told the same cam grinder that it was going into a 2800 lb Duster with the same 4.10's and the only "off road" use would be a trip to the local dragstrip, you'd been recommended a complete different grind.

I was gonna pass on this, but a random neuron just fired and I thought I'd share this..........
You want a cam grinder of the level of skill and knowledge of the late Clay Smith........in his day there are those who would say there was none better, he was a master of his craft. His knowledge and insight of air flow thru an engine allowed him to grind each lobe on a cam to maximize the event on each valve in each cylinder.

I'm not doubting or questioning Mr Jones expertise or saying I won't be using this cam. I'm just surprised at the seemingly short duration. Then again I've never ordered a custom cam, always settled for the off the shelf CHEVY" cams they sell for mopars.

Call Hughes Engines and see what they recommend. The more the accurate the info you give them (any cam co.) the better the cam will fit your needs.

Call ten different cam grinders and you will get 15 different answers.
Always tell the facts to the cam guy and pick the guy you get on with best. This is how you get the best cam.
If you are talking to someone on the phone and it just doesn't click, you should probably move on. The ability to communicate, and th ability for someone to "get" what you are saying is much more important than the numbers.

More to hate...............another random neuron firing.........
I think you're just funnin' us here, askin' us to pick you a cam just like a nube.......when in another thread you left behind over 20 posts about cams, cam timing, lobe shape, where to install them(and I don't mean where the sun don't shine), a lot of knowledge, a lot of information to be sure.
Thanks nube...........

The induction tract and more specifically the cross section and length of the intake and ports and their air speed -relative to displacement, is what determines where an engine peaks at (RPM). The cam takes a back seat in determining where peak power occurs. In fact I would say in order of importance is CSA (cross section area) , then, exhaust size/length, then camshaft events. Here's a link to a 318 with a 205/210 @ .050" cam and it has no trouble peaking @ 6000 rpm. J.Rob

Does it idle like a sticker or have a little like to it?
