Yea I just wanna hear how these cams sound =D

 

Should be up and running this weekend. Taking my time. The car is parked for the winter. I know u Texas guys don't understand what winter is

They have a nice mild lope to them. Can def tell the car is cammed.

 

I cant talk either my car is down for the winter too and im wiring a ton of new goodies up!

 

Starting to look like a motor again



The exhaust manifold and downpipe will be bolted on today.

Tomorrow, fresh coolant, oil & first start up!!

 

What about tune?

 

I thought he was sticking with the GM Stage 3 tune.

 

GMR S3 PCM/Calibration. Just as in the build book.

I may tinker with it when I get her on the dyno in the spring though.

I am.

 

This head is going to move a considerable amount more airflow. I think your going to end up needing hptuners for maf correction

 

We shall see. I will log it and see where I stand.

The GMR calibration hasnt failed me yet.

I wont be flowing as much as the build books engine due to a less aggressive cam profile (Comp/ZZP S1 vs. GMR), so I may be ok.

Everything will be checked. For now, I just want to get her started up and running.

 

how nervous were you last time on the initial fireing?

 

Every one is nervous their first time

 

The first time is the best 13 seconds of your life

 

lol

 

so you can really run the car on the current tune?

x2! pleeease get em up on youtube

 

Especially when the can sensors not clocked right and it back fires when your crank it
I Damn near shat myself

 

they used a custom ground set of cams in the build book

 

I know that exact feeling. When I did my valve springs it was clocked wrong, but I was low on fuel so after it took a few seconds to start I drove to the gas station. Filled, went to start it, cranked for 5 seconds and BOOM!!! Everyone stopped and stared...tried it again, BOOM! A guy came out and yelled at me So I pushed it off to the side, waited and tried for a half second and it fired right up! Went back tot he shop and got it clocked right and had a story to tell lol.

 

I never had mine backfire just wouldn't start

 

There seem to be 2 ways that it will start after about 5 seconds, 1 way that it works correctly, one way it starts every time but throws a code, 1 way it will not start at all, and one way that it will start late sometimes and backfire terribly sometimes lol.

 

Ahhh I hate that blasted thing.

 

Ya I just threw in my new cams and gotta put that **** suckin thing on still. Such a bitch because you're shootin for the hole like bangin a fat chick and hoping you're lined up.

 

I do not know that feeling lol

The last 2 times I did it I got the sensor line up first try. It takes a steady hand. Also deleting/re-locating a lot of the **** that was back there helped make room too lol

 

Ohhhhkayyyyy we got the American Rico Suave here

 

Lulz
My method after 2wrong tries is guess and check
Aka install, start , scan for dtc

 

Hahaha, yup.

This is actually by second time timing the car, so I feel 100% confident she will fire fine.

Last year, I had some issues with the CPS and timing in general, but got them figured out.

This year it was a breeze. These cars are cake to work on.

This.

I perfectly brought the car to TDC via the timing mark on the harmonic balancer & front cover (intake cam @ 2 o'clock, exhaust cam @ 10 o'clock).

Rotated the CPS wheel to line up with the timing mark on the outside of the housing, and popped her in. She slid in with ease.

Yes sir. How do you think I ran my cams??

I have no worries that the GMR tune will run just fine. I've had lots of convos back and forth with Bill Duncan (the GM Engineer who helped develop the tune and the engine in the build book).

Last time (last year), on my initial start up, I had some issues. Car was out of timing by a tooth, due to the chain jumping while using the kent moore cam sprocket tool. Retimed the engine the right way, and she fired right up.

This time, I'm much more confident. I've gone over everything a million times. She should be good to go.
