Looks like the final pieces of the puzzle are coming together and it should be competed by next week.

What started out as a mild 350 rebuild of a L98 with 083 heads has morphed itself into a -

355 with 062 Vortec heads ported to flow 230,
hotter cam 226/234 112,
9.7 to 1 compression,
self aligning roller rockers,
1-3/4 dyno don headers,
serpentine system (smog delete),
CCC Qjet rebuilt with these specs in mind.
Edlebrock Performer RPM

So I walk into the engine shop where the work is being done and I ask the million dollar question.....

"What kind of power are we talking here?"

After some number crunching, I hear "oh about 400"

I said "at the crank"

They said "yep"

I said "Holy S&$)!!"

Well after some failed attempts to actually swap the motor, all I need to do is undo the bellhousing bolts then this L69 is outta here...

Are you sure about that? I was under the impression the only Vortec spreadbore available was the standard Performer, not Performer RPM (there is a non-Vortec Performer RPM spreadbore available).

You're right... My bad it's a standard performer

Air cleaner setup

Chuck84TA

Decided to pull the A/C. Going to put the chrome valve covers on too.

The CCC qjet actually runs well. Still needs a TPS adjustment after I get the timing set though. It's a rough idle but the motor doesn't die at idle //700-800 rpm

Where did you get that air cleaner setup? And I like the swap. I'm doing the same just need to figure out what I need yet other than the engine!

Chuck84TA

I found it on eBay
The air cleaner came from a 1984 Z28, so I just used my original al L69 air cleaner cover instead.

I really like the way it turned out !! Especially with the chrome covers and Pontiac blue paint on the block, kind of the old school Pontiac look I was shooting for

I will say this.... I needed to remove the a/c compressor to fit the passenger side intake, since I am using a serpentine belt system.... Oh well... I've got t tops anyway

i have unported vortecs on the 355 in my Camaro with the same intake as you- but with an Edelbrock 1910 850cfm quadrajet- with a .488/.510 lift cam and long tube headers.. i was out playing with my trusty old G Tech meter last weekend, and it said i was going 105 in the 1/4 mile with a bad bog off the line and a 700r4 that doesn't shift consistently.
