70 L78 Camaro - Dialing in more originality

[DarrenX33]

A few member have asked what I have been up to lately. So here is the explanation. I pulled the LS6, M22 tranny and exhaust out of the car to make way for the new. The motor is now numbers matching to the car as is the tranny. Headers are gone to make way for exhaust manifolds and smog. Here are a few shots.

From the top.

Very cool D!

[Mr.Nickey Nova]

Look's good D,can't wait to hear it running.

[Jeff H]

Looks great! When did you get the numbers matching (VIN matching?) engine for the car? I always thought the TCS was only for automatic cars though.

[CamarosRus]

I believe Darren has a appropriately dated CKO coded engine. It is not the engine, born with his L-78 body.

[/ QUOTE ] Thanks for answering that for me Chuck. http://www.yenko.net/ubbthreads/images/graemlins/haha.gif I'm sure everyone is well aware that it is not the original motor. I am not hiding that fact nor do I care that it is not the "born with" motor.

[wheelhop]

nice work D, keep the pics coming.

[Jeff H]

Ok, I was gonna say how in the heck did you find the original motor. http://www.yenko.net/ubbthreads/images/graemlins/shocked.gif So what is that TCS for exactly, I thought it was automatic only but maybe I'm thinking of the anti diesel solenoid. Isn't the L78 also supposed to have that fuel line support bracket that bolts up to that front carb mount stud? Looking good!

[COPO 70 RS/Z28]

Looks great Darren...

Neat Post, I really enjoy these 'Make-over' threads.
Keep the pics rolling.

Reminds me I thought Seattle Sam was working on his 70-L78 mill makover,,,,

Jim http://www.yenko.net/ubbthreads/images/graemlins/youguysrock.gif

[al8apex]

the 4 speed Z28 had the TCS switch, not sure why the L78 manual trans wouldn't either ...

[CamarosRus]

My 70 SS L-48/4spd Camaro also has Transmission Controlled Spark, as does the L-34.

I cant recall which 70 Chevrolet doesnt have it ???

[JRSully]

70 L78 4 spds would have the TCS as well.

[TimG]

Looking forward to seeing the finished product, what a nice car.

[olredalert]

-----Darren,,,Engine looks great! Im certainly no authority but wouldnt the PCV hose go around the front of the motor, not the back. I never like its proximity to the throttle linkage when it goes around the back, but thats me........Bill S

It hangs on two clips mounted on the rear of the dual snorkel air cleaner.. Thanks to all for the compliments. http://www.yenko.net/ubbthreads/images/graemlins/biggthumpup.gif

[Andy]

Wow! Looks really good! http://www.yenko.net/ubbthreads/images/graemlins/biggthumpup.gif

[ORIGLS6]

That's been a topic of discussion on my car too Bill. My car didn't have the clip on the back of the dual snorkle and the PCV hose has always been routed to the front.

It's been pointed out to me by many 'experts' in the field. I know how it was delivered and I know how it's gonna stay. http://www.yenko.net/ubbthreads/images/graemlins/grin.gif

Lookin' Great D! And if you want the fuel line bracket give me a call. I have a spare.

Does Gavin get the first ride? http://www.yenko.net/ubbthreads/images/graemlins/biggthumpup.gif http://www.yenko.net/ubbthreads/images/graemlins/biggthumpup.gif http://www.yenko.net/ubbthreads/images/graemlins/flag.gif

-----OK! http://www.yenko.net/ubbthreads/images/graemlins/blush.gif Hope you didnt take that as a diss as it wasnt intended that way. I have been looking at alot of Holley equipped cars lately trying to figure this out, but apparently the factory would run it either way. Some engineer somewhere probably had a reason.......Bill S

At least that is what the assembly manual calls for. Maybe they stopped using them at some point. They are a PITA and Dennis would have know if he had them the first time he tried to take the air cleaner off.

[ORIGLS6]

My car is a late build so maybe they ran out of clips. But the hose still ran around the front. http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif

http://www.yenko.net/ubbthreads/images/graemlins/grin.gif Never took it that way. For one thing, I am no expert, just someone who does a LOT of research and who is passionate about correctness on the cars I restore and agree totally with what you have said before, NEVER SAY NEVER!!!

Sweet Darren, sweet!!! When can we expect to see it on the road...Lombard, Rolling Meadows, Goody's??? http://www.yenko.net/ubbthreads/images/graemlins/biggthumpup.gif

[DarrenX33]

With fingers crossed it should be running this weekend.

[70 Forest Green Zee]

Awesome D, your car was beautiful before you started this process, I can't wait to see it now!!! http://www.yenko.net/ubbthreads/images/graemlins/biggthumpup.gif

[DarrenX33]

Thank you Randy and all. I appreciate it. http://www.yenko.net/ubbthreads/images/graemlins/worship.gif

[Jeff H]

I never really thought about the TCS setup so what does it really do, pull timing? I know I've seen it on a bunch of LS6 cars but never really noticed it on the L78 cars. The 70 L78 Camaros had a bunch of really strange 1 year only things going on so we still have a lot to learn. http://www.yenko.net/ubbthreads/images/graemlins/biggthumpup.gif

[mockingbird812]

Been learning a bit about TCS (Transmission Controlled Spark) with my '70 Nova recently and basically it does not allow vacuum advance of timing in low gears: 1st & 2nd for TH400 and 4 speeds. It is an emissions reducer.

[resto4u]

TCS= temp. controlled spark. Not transmission controlled spark.

[olredalert]

-----In light of that, Sam, would a guy be wise to make the set-up non functional one way or another??? It could easily be done in a way that still appeared as though the set-up was fully functioning. Sort of like gutted smog-pumps.......Bill S

[mockingbird812]

Hey Bill,

You bet I plan to discretely disconnect this system (haven't figured that out exactly).

I still contend that, altho temperature is an input to the TCS system, the primary input is what gear the transmission is in, therefore TRANSMISSION Controlled Spark. Temperature input is a go, no-go sytem (I think http://www.yenko.net/ubbthreads/images/graemlins/hmmm.gif). Vacuum advance is available while car is cold, but once the water temp switch (I don't think it is a sender but rather a switch) says its warmed up, then the vac. advance is cut out (in low gears).

[al8apex]

The switch on MY 70 Z28 4 speed is a TRANSMISSION Controlled Spark switch, it does not allow any vacuum to the distributor until it is in 4th gear, one of the FIRST things bypassed or thrown away too ...

[CamarosRus]

http://img.photobucket.com/albums/v470/CamarosRus/Seymour70Z28/Exterior112.jpg

[JRSully]

You can actually re-route the vacumm lines on and around the TCS switch itself, it will continue to look correct and will void out the operation of the switch.

[DarrenX33]

Exhaust installed as well as most of the smog. Should be firing it up tomorrow. I'll have more pictures then.

[mockingbird812]

Uh, er, sorry 'bout side trackin' your thread Darren http://www.yenko.net/ubbthreads/images/graemlins/blush.gif Lookin' forward to follow on photos. Good luck!!! http://www.yenko.net/ubbthreads/images/graemlins/laugh.gif

Looking Good Darren. That is motivation to finish mine....

[Seattle Sam]

Darren,
It's looking great - let's see some more pics!

[DarrenX33]

Engine fired yesterday. Still have a few problems to sort out till I get it on the road. http://www.yenko.net/ubbthreads/images/graemlins/no.gif

Sorry about the lack of pictures. Been difficult to shoot pics with so much going on .. http://www.yenko.net/ubbthreads/images/graemlins/frown.gif

[COPO 70 RS/Z28]

Sounds Great, Are you over the hump Darren???

Cant wait to see the action shots!!!

http://www.yenko.net/ubbthreads/images/graemlins/headbang.gif http://www.yenko.net/ubbthreads/images/graemlins/headbang.gif

[DarrenX33]

It has been running and nothing bad has happened. Phew! Mostly small stuff at this point but enough to keep me from driving it. Hoping to sort out real quick (this week) then with the weight lifted I can shoot a lot of pics.

[Jeff H]

Good deal! It can be pita when you make a bunch of changes at once and it doesn't run right. You'll get it sorted out.

[DarrenX33]

Its pretty much ready. Just a few items to sort out and some fine tuning but it should be roadworthy now. Just need to wait for a break in the rain to get it out on the street. I have video of if running but it is too large for Photobucket. Trying to work around that..

New exhaust.

http://img.photobucket.com/albums/v674/dagcostello/IMG_3625.jpg

[Xplantdad]

D...if you are using a Win XP(that's what I remember you having)...you should have Windows Movie Maker installed on your system...

Just load the file into it...and output it to a smaller file size (it's pretty self explanatory http://www.yenko.net/ubbthreads/images/graemlins/grin.gif).

Then you can load it up to Photobucket! http://www.yenko.net/ubbthreads/images/graemlins/beers.gif


By the way...the Camaro looks bitchin! http://www.yenko.net/ubbthreads/images/graemlins/worship.gif

[Mr.Nickey Nova]

Sounds great (D),what exhaust system did you go with??

[DarrenX33]

Thanks guys.. The exhaust is a Parts Place system. Probably took about 2 hours to install it. Pretty much fit like a glove. As nice as it would have been, I couldn't really justify a Gardner system. At 1/3 of the cost I am pretty happy with what I have.

[CamarosRus]

Darren, Curious if you used Jack Seymours hangars (OEM repro) to support muffler and tailpipes ?????

Are you using one of the 143 cams from Jim & Rob? Sounds nice! I bought one of these for my L78 also.....
I might tryout the same exhaust system that you used for my L34 car....

Scott, on the recommendation of my engine builder and blessing by my "go to guys" Jim and Rob I went with a Comp Cams 11-218-4.

[CamarosRus]

Darren, I completely understand and agree with you using this very acceptable alternative to GARDNER.

Does Parts Place make a small block version?? Will you show more pics of tailpipe detail and other shots.....

FYI.......Jack Seymour will be attending/judging at G.M.Carlisle, June 26-28th. Anybody attending and needing his exact repro 2nd Gen Camaro/Firebird hangars, suggest they contact him so he can bring your order.

[DarrenX33]

No problem I can do that. Parts Place has SB as well I believe.

Had it on the road tonight and it runs well. Now I need to break it in so Lombard is in order for Saturday. It was a great feeling to get behind the wheel after all the work and help from some great friends. My thanks to John P. and Steve at D&R, I couldn't have done it without you guys. I promise more detail pics to come as the pics I took tonight with flash didn't turn out so well.
