I have a set of fully ported and polished 113 heads that would have been good for this build.

 

Making progress. Almost in the home stretch.

 

Cut the stock N10 pipe out before the cats. Only managed to cut one of the 2 air pipes (lol sorry muffler shop guy).

I only have a single cat Y for my dual cat setup so hoping I can get a fresh set of dual cat y pipes soon... or have a shop 'connect the dots' and fill in the missing part of the Y

 

Tight is an understatement. Got the drivers side on. It was quite a task for only being 6 bolts.

It fits, but with no room for error! Now for the.. hard side? =/

 

Got the passenger side on. Had to loosen and move a hard coolant line. Otherwise, bolt-access aside, a lot smoother. Let's hope I can install the flexible oil dip stick without removing it...

 

Had to modify the ignition coil bracket for the accel / edelbrock intake manifold. Who knew? This forum, posts dated as early as 2002 mentioning it! This place is a fantastic resource.

 

Instead of modifying the the bracket, I just inverted it and mounted it to the underside of the cowl.

 

We got the SR installed tonight. Took the wife and I 4 hours. No special tricks, didn't need to remove rockers, etc. Long ball-end allen keys works great. We were real meticulous about the bolts; got everything snug tight then did a full tightening round.

Never thought I'd see this thing installed.

 

They are a great intake but a bit of a pain to install at times. Looking good!!

 

Almost done. Got the SLP airbox all in, charcoal canister moved and plumbed in, throttle body, and several other things. Muffler shop tied in the dual cat setup, but I should get one ordered from Don ASAP (time is running out) as its not as nice of work as he'd have done.

ToDos include installing the heated o2, smog diverter valve or whatever it is, ac compressor (though will be disconnected until I have it charged,) button things up, add fluids, and.. hope for the best.

Hoping i eyed timing good enough on the dist. I am not sure if I'll cold start it with the ESC disconnected and try to get an initial time in before raising the rpms for a bit or just go by ear until 'break in' is done and I can idle time it at running temp.

 

Love the looks and power those make!!!

 

Firing her up in the morning. Fingers crossed.

 

First start (1500-2000rpms for cam break-in even tho its a roller)

 

 

Finally got everything kinda buttoned up right, timing is good, bad MAF diagnosed and swapped, idle set right (IAC location ~5-10) and it's doing.. ok!

Was able to datalog some and it's definitely lean, as expected with these changes. Showing 160 BLM / 140-150 INT. All at idle. Leans out as the engine warms up (again, kinda as you'd expect.)

The heated o2 helps things enter closed loop pretty darn fast.

 

 

The car passed smog today.. barely, but it did it!



Had zero issues with any of the visual stuff. I walked in with a book of EOs for every part, so that probably helped.

 

Bring it out to Jack in the box (Florida between sanderson and kirby)Fri nights in Hemet.

the measurement you had of 535 was barely passing but it did..what was that for? nox?

 

It was nox, yea. Still working to figure it out.

 

Whats your max on HC's?

 

 

Im surprised your nox is that high w/ two cats.Great job nonetheless! Always wanted a lingenfelter set-up back in the day.

 

Yea, I am going to triple and quadrupedal check for any intake leaks, but haven't found any yet.

I get code 32 at cruise, but verified EGR is working and getting vacuum via gauge so... it's one of a few things. I have another thread on it here: https://www.thirdgen.org/forums/tpi/...pi-5-0-vs.html

 

does that use an EGR switch or solenoid? Had one on a C4 same code took awhile to track down.
how do you like the power? installed acouple of those cams when they came out never got to drive them

 

It uses a solenoid, as well as the temperature switch. The trifecta of EGR BS!

The car builds steam at 2500 and just doesn't seem to run out of breath by the time the 700r4 shifts. Even at 5500 it didn't feel like it was gasping for air like it used to at 4500.

 

NICE! Any update? How does it run? Was it worth the work and $4 over the LB9 305? Asking because I'd love something like this (minus the headers and "Box" style intake. I too, have to pass ca SMOG, every 2 years.

 

Vortec Heads are not a good choice unless you do this. Look at the Dyno Header with the mod for the crossover tube. This will pass Cali Smog. A TPIS ZZ9 Cam was used.

 

Is the SLP Airbox "Ca approved"? It Looks like something a SMOG Tech would be concerned about. How would it run power and emission wise w/ the stock PFI upper and lower manifold?

 

Funny I have the same cam in a 350 Vortec. Degreed spot on at 214/220 just like the Crane 2032. Bought from GM with the same part number on the cam tube.
