Custom Ground Cams

[haasguy]

Yes, I know it would be expensive, but has anyone ever found a place that would be willing to grind a custom set of 3.4 cams. I know that the cams are not up to the specs that are listed in the factory manuals. I'm not looking to have mine reground but I'm looking to have a set made from billet stock.

Thanks

Yes, I know where to get them done. If you are going to make some from billet, let me know how much cause I have some specs that would be worth trying. A regrind will put you at GM spec btw.

Go with Quad 4 W41 Specifications: .410" Lift 219º duration possibly 300 horses (guessing, but it looks good) little lopey though

The 13* exhaust retard timing makes it lope. Muscle cars lope. Personally I don't care how bad it lopes, as long as it doesn't effect driveability and things like the charging system. All I care about is being able to tune it, not have it stall at every stop, and not have it shake the car to peices at low rpms in first gear in something like slow moving traffic.

I did a web search for "custom cams" and turned up this company. I haven't called them, but does anyone have experience with having a stock cam welded up and reground?

Send us your original
cam core for regrinding

Because of slight variances in different camshaft models we find it is safer to use customer's own factory core. Not only will it lower costs but also will result in better quality because of extremely hi-grade metal used in factory cams, especially with import cams.

We guarantee a correctly installed center line and offer long lasting, quality workmanship.

Please note: Exchanges are available on most models."

With what they are offering it seems like you could have W41 cams in your engine.

[SappySE107]

Havent talked to them about doing cams. I have no idea. I assume you meant W41 spec cams.

[sspeedstreet]

Yes, W41 spec. I was not aware cams could be built up by welding the lobes. I'm going to talk to them on Monday.

Ask them what welding process they use. We used to send our cranks out that had spun bearings really bad. The company used a process called Submerged Arc welding. We would get them back with rough weld beads, then grind them down to stock perameters. Was really fucking hard on the Crank grinder but the end result was a perfect journal.

If you've ever welded cast iron you'll know that it's next to impossible to get a weld with no porosity. In other words, it wouldn't exactly produce a nice surface for a bearing or lifter to ride on, but submerged arc seems to do the trick.

Has any body got prices on this work yet. I'm really interested.

"Ask them what welding process they use".

It's going to have to be a heck of a lot harder than a crank journal would be. Maybe they nitride them when they're done.

I'll ask about a quantity discount! I'll post as soon as I get answers.

OK, here's what I found out . . .

Really a nice guy, easy to talk to. He says he does a lot of work on 2.4s for people, but wasn't familiar with the LQ1. Here's what I'm sure you want first:

First set of four cams (including computer evaluation of the stock cams and design to your specs): $640.00 US. An order of 3 sets will get a "considerable" discount. He did not specify how much, saying he needed to see the cams.

Step one: Someone needs to take a measurement related to the lifter and cam carrier. He explained exactly how he needed it done, but I'm not knowledgeable enough about the heads to understand what he was describing. Someone (Ben?) needs to call and get this info.

COLT CAMS, #54 - 3347 262nd Street, Langley, BC, V4W 3V9 Canada
TEL: (604) 856-3571, FAX: (604) 856-3572

Step two: He needs a pair of cams sent to him, marked with rotation and "intake" or "exhaust". I have a spare set, so I can do this.

He needs this to decide whether it can be reground or will need a build-up. I told him it was my impression someone said they couldn't be reground, but he said he's heard that before and has been able to do it.

What do you think? Can we get 3 people to commit to this?

re: custom cam regrinder

I am pretty amazed; suddenly it looks like cam grinders might be falling out of the woodwork!!! I have been talking to ANOTHER company - also in BC - ??? that custom grinds cams; I found them thru a motorcycle custom cam search/site etc. They have been grinding cams for something like 300 years... (it IS a long time tho)

I talked to the guy a few times; told him it was a dohc setup; no rocker arms so cam dimensions are critical etc etc, he had NO problem with all that siince it makes it very similar to a TON of engines out there now....... Honda, Toyota, etc; and he has done a LOT of welding up and regrinding etc etc.
MOREOVER, they already did a bunch of research on this particular engine and setup by getting a set of cam carriers and cams etc to do a bunch of measurements and to try to figure out what they were up against.
ALL that being said, I am going to hold off till I hear from them; but that should be anyday now; on whether or not they want to get into this business. I told them I would not 'unleash the hordes' on them until I heard from them.....

I might be nice to have a choice but I will wait to see. Will contact them asap and pass along any good news.
