Thanks for posting for this non-FB using weirdo.
Looks like a great time. Some badass mullet camaros. It's amazing how much you have done to yours in comparison to the older pic you re-made.

Yeah, been busy lately...my mom had a stroke last week, but she's doing well. I do have a whole shitload of parts and stuff to post up. I'll do that soon.

So, for those of you who like stories, here's where this one starts... I've been itching to get back to the drag strip lately. Talked to Lisa and Jay and set up a day at Lebanon. I even rewired my dad's new trailer so I could haul it up there in case I broke it (like the last time I was there). Made some practice runs with it on a back road and had trouble with the 3-4 shifts at redline (oddly enough - just like the last time I was at LVD).

Under 5000 it shifts like butter, but anything above that and it would rarely take it clean. Sometimes a quick stab will stick if it won't go in clean on the first try. One run I hit 2nd instead of 4th on that re-stab and spun it way past redline...I'm guessing 8500-9000 according to the gear ratio calculator. It still ran and I did drive it home, but I could hear that it wasn't happy. Compression test showed a few cylinders a little bit low, but with #5 at 45psi. Hoping for the best I checked the pushrods and they weren't bent enough to be the problem, and my borescope confirmed a new valve relief in the piston. So I yanked it all out.

All 6 pistons hit the exhaust valves, and 4 of the intakes had light kisses. I was wondering how my timing chain would look after 11 years with the UDP, but it looks pretty good. Sprockets too. One thing seemingly missing though is the new syncros that were to be installed by Midwest Trans back in 2013. I could swear the new syncros were brass colored, and the ones in there look just like the ones in my initial rebuild photos...

Syncro clearances check out according to Jeff at EP and the tooth to tooth check Midwest Trans had me do also checks out. Shift fork appears to be fine. Jeff is thinking shift cable actually. There is a little bit of wiggle for that plastic retainer on the steel shift cable end and he thinks that might be enough. Seems hard to believe it would cause a problem with the 3-4 and not the 1-2, though. Or even a redline 3-2! I'll fix it while it's apart, but I'm not sold that's the cause yet.

FWD cable shifters FTL....

At least my man trans shifter is connected to the trans with a solid bar. Yes I'm talking about my 5-speed daily car. :crazy:

Well I have two man trans shifters that are bolted directly on top of the transmission. And one of those has 6 forward gears. :P Just now digging into why the reverse lights no longer work after the rebuild from Midwest Trans. I see how it's supposed to work and the bar does contact the switch, but there's just enough slop to not close the switch. Same deal with a brand new switch. Works when plunging by hand, but not with the bar in the trans. I think the easiest way to get around that is going to be to chuck the switch in the lathe at work and turn down the face a little bit so the plunger sits deeper in the trans. I'll try it with the old switch first so I have the new one as a backup.

But enough about the trans for now...I got a bunch of engine parts to play with. I bought the Wot-Tech Stage 2 heads & intakes from Tyler. Some queer vandalized the UIM with profanity, but I'm not using it anyway so whatever. Heads look nice. Chambers look as good of quality as my AFR small block heads and the exhaust looks even better, but the intake runners aren't quite as nice.

I CC'd the WOT heads and the stock heads to figure compression ratio and because I was curious about the runners. Results were surprising.
The stock 2004 #12580234 head was 28cc chamber, 111cc intake runner and 70cc exhaust. Pistons are 28cc.
The WOT ported older #10218170 head was 28.5cc chamber, 114-116cc intake runners and 71cc exhaust.
Not much volume difference in these heads. Hoping they are worth the money. By comparison, most SBC heads are 155-170cc intake runners with 1.94/1.50" valves, and the AFRs I bought are 195cc with 2.05/1.60" valves. A lot easier to see where the extra flow comes from there...

Figured I'd test the valve sealing on #6 for gigs. If it won't hold in water at 0psi, it sure as hell aint gonna hold in air at 180...

Depending on whether I go with a stock head gasket or a Cometic, C/R will be 9.55 or 9.83:1.

What about Camaro 3.4 head gaskets

Intake ports are not supposed to be polished like the exhaust. You want them to have texture to keep the fuel suspended in the air. That's been pretty common for porting the intake side for a while from Ben.
