I'll prolly put these in a spreadsheet format to make it easier to decide between cams. Obviously, some of these are a bit too mild for us and some are probably a bit too extreme for us.

I can get all these cams. If any of you are interested, please PM me.

Yep.....our duration is really that low. Ever driven a stock truck then driven a truck with a 412/422? VERY noticeable difference. Ya gotta remember, our trucks came with the NA 4.3 grind. Hell, even the Astro/Safari cam would have been a major improvement over stock. Ah well, that's just another place where GM could have done much more with these trucks but they didn't. :roll:

so i have the biggest stock cam on the list

so i have the biggest stock cam on the list

* '92-'95, Vin W, w/ balance shaft
- Lift (I/E) - .432/.440
- Dur @ .050 (I/E) - .208/.208

so according to this, the stock cam in my engine im putting in will be a good upgrade over the stock z code engine i blew up? with that cam and some 1.6 rollers i should have some good lift for stock cam then? will i notice much difference with this over the z code engine?

awesome info, thanks

Yes....this camshaft is a noticeable upgrade over the stock SyTy cam. So much so, that if you are looking to get all that you can from your combo, I would definitely have someone do a custom chip around that cam. The stock chip will work (as the cam isn't that radical), but there's more to be had from that cam with a chip made around it.

Careful with the 1.6 rockers. You may get close to coil bind on your setup with the added ratio. Not sure of the max lift for the stock L35 springs, and you may be fine even with a 1.6 rocker, but have it checked.

FWIW, I just got off the phone with Lunati and they DO NOT offer any hydraulic roller camshafts for even fire 4.3 V6s.

Just my luck........I was just quoted $80 for some of the cams from my suppler. :(

I do dream of a cam with 220/225 @112 with 0.60 & 0.65 lift
Not that wild but with big lift...i guess solid...

Here's Isky's Hydraulic Roller Cam info:

---------------------------------------------------------

ISKY

* 131252
- Lift (I/E) - .450/.450
- Dur @ .050 (I/E) - 204/204
- LSA - 112

* 131257
- Lift (I/E) - .465/.465
- Dur @ .050 (I/E) - 209/209
- LSA - 110

* 131252/257
- Lift (I/E) - .450/.465
- Dur @ .050 (I/E) - 204/209
- LSA - 110

--------------------------------------------------------

Seem to be pretty good specs for those not wanting to upgrade valve springs on stock heads, but want a decent increase in performance. Unfortunately, Isky seems to be right inline with other manufacturers (pricewise)........right around $240-ish per cam.

So What about the GM performance Cam PN# 10051147?

So What about the GM performance Cam PN# 10051147?

From the catalog, this cam looks like a pretty good replacement and can be had from GMparts direct fairly reasonable?
Anyone use the L79 grind? Doesn't look like it would throw the ECM off too much, could be very tunable.

GM PN# 10051147 OLD L79 Style cam
- Lift (I/E) - .447/.447
- Dur @ .050 (I/E) - 222/222
- LSA - 114

Then there is GM PN# 10134321 Not sure about this one, looks interesting.
- Lift (I/E) - .450/.460
- Dur @ .050 (I/E) - 224/224
- LSA - 112

From the catalog:
The following camshaft kits were designed and manufactured by Crane
Camshaft Co.® for GM Service Parts Division. These camshaft kits include
(1) camshaft and (12) tappets.
