Custom Ground Cams

[SappySE107]

I wont be trying them, as they are sold. Talk to them for information, that is what I shared it for.

Alrighty then!

What do they do? Do they just regrind or do they weld and then regrind? Where can I compare the '94 LQ1 specs to the Quad 4 W41 specs. Ben, you said you had as set made already, when will you be trying them?

Lyle

The W-41 specs are; duration of 218 degrees @ .050" and .410" lift

[grandprixgtp_91]

what would be a good lift and duration for our cams to still pass emmisions and hopefully get close to 300hp from stock?

[VerbotenZ34]

Ok, so let me get this straight: For $500, you recieve four reground camshafts (2 int, 2 exh) that reproduce the GM stock camshafts.
Are GM stock spec camshafts the same listed here and developed a ~45 HP increase on the Desktop Dyno?

If this is so, sign me up baby!

You can probably get those specs.

[VerbotenZ34]

In plain, layman's terms (and keeping in mind that cam timing, lift and duration are all monkey business happenings that I'm not 100% on), what would be the better camshaft: GM Spec or Quad-4/W41? I'm going to rely on you guys to point me in the right direction here, as I'm pretty clueless when it comes to the really nitty gritty of our engines,...

For some reason i doubt the desktop dyno is exact on that. We need to have someone dyno this.

I cant answer that...but different people will prolly want different specs for different engine setups.

even manual and auto people will prolly want different specs

[Lyle's GTP]

Does any body know the over-all dimensions of the Cams in our engines? I'm thinking about machining my own blanks. But need to know what size of steel to use, so I can get prices before I consider it.

18 9/16 long by 2.167

Cool! Thanks.

Personally, I think one of the master DOHC guru's should do layperson's a HUGE favor for this process. Please comment with what you think.

Those that know all the little ins and outs of the cam specs should think up of different specs and classify them in states here on the site. Possibly W-41 (stage 1), GM, (Stage 2), custom (stage 3), etc etc Whether auto or manual, I don't really SEE, imo, how much different a camshaft HAS to be for a manual or an automatic. With this done, this will remove the guess work other people, such as myself, would probably have when ordering/buying the cams. This is something I am for sure interested in, but don't wanna be second guessing whether or not I ordered the right thing for my car.

Just a thought.

the autos would need to have more vacuum then the manuals would.

I got the prices on the steel, it will be $106.00 for 7 feet of 2 1/2" 8620 steel. I also got permission to use the lathe to build the blanks. So, I still have to see if I can find some body here who could finish grind them for cheaper than the caddy guys.
