What are symptoms of #9 or #10 camshaft lobe wear?

The ones I got out of donor vehicles were fairly clean. One set had sludgy oil(not a milkshake, but the result of not changing the oil frequently enough) all over them though. I've pulled four sets so far. I still haven't installed them yet in my Red TGP, my other two GP's have them though.

I guess, I cleaned my rockers and guides with degreaser in a parts washer at work. :laugh:

Well it was the fact that I didn't want to deal with the gunk getting to the guides (studs have to come out) . Plus my engine is clean while already having the plate for easy access. If it was not my tools, I woulda pulled them in a heart beat! lawlz

All I did when I put the 94-95 1.6 stamped rockers in, was swap the pushrod guides out for the newer style (deeper slots in the newer ones)

Rocker arm studs are the same.

But what if you are changing the springs to the LS1 springs with the 1:6 rocker arms. Can you still use the stock studs or do they need to be replaced?

Will these injectors work in the TGP?

Help! I have tried to price a Crane H260 camshaft on Summitt and Jegs but they do not have it or list it. Where can I find one? :icon_mad:

Yes, They will work fine for a pretty much stock application...

I have a set of 22# injectors (it's either 22 or 23 I forget [3.4tdc] ) . I also might have some 28's. I doubt you'll need anymore than 22 or 23 for mild mods.

RICHTGP · January 05, 2009, 05:26:01 PM

Hey!! Thanks for everyone's input. Have most items ordered and on the way. Have ordered H260 Comp Cams camshaft kit with lifters and timing chain; Aurora 23# injectors, 1:6 stamped steel rockers; LS1 valve springs and shims; Retainers, and keys. Still need input on who is tuning the chips for the TGP so I can talk with them and see what is needed for my car to perform with this new setup and what the cost will be. Thanks!! Can't wait to see if these upgrades make a noticeable difference and if so how much difference between the way it was. Please let me know if you know!! Thanks again. Mike :icon_cool:

Talk to Kenny (TGPilot) or Flybynite for your tune.

RICHTGP · January 05, 2009, 08:43:35 PM

Kenny or Flybynite, Please PM if interested in doing my chip. Iwould like to talk with you about this! :icon_biggrin:

Has anyone run the 23# Olds injectors from an Aurora? Will they run good in a slightly modified TGP?
Have a great day!!!!!!!!

TGed · January 06, 2009, 06:56:38 AM

Realistically you could use 24# injectors and as long as you're tuned with the injectors is use, it'll be fine. Now if you slapped some 36'ers in there, tuning will get harder slightly and they'll be over kill.

With any injector upgrade though, you will NEED a tune, and with using 23# injectors, it should be simple enough to tune for while not "wasting" injector duty.

Kind of like having a cup for your drink. All you want is 8oz's, but you're stuck using a 20oz container since that is all what you have. You never quite fill it all the way but the extra space is there for when you get really thirsty or grow to "fit" the cup size.

Thanks. talked to Flybynite about the chip tune and I am going to get that done also.

Dropped the engine out of the body with the trans annd cradle attached. Removed the camshaft and sure enough #10 lobe was half the height of the other exhaust lobes. Problem found. Installed new H260 cam, LS1 springs, shims and retainers, lifters and am installing the 1:6 rockers. Is it required to modify the guideplates? Some say yes and some here say no. Also installed the 23# injectors into my rail. Hope she runs good when I get it back in! :icon_biggrin:
