Corvette V12?





HA- reading the owners manual would have been my first clue!!!
Actually I saw an episode of "Roadkill" and they upped the calipers to 6 pistonon an ElCamino- with the stock size bore MC they couldn't get enough braking out of it. I had an "Aha" moment- pulled out the Owner's manual - and that's what they (Wilwood) recommended!!! Anyway- glad I had not filled the system- so I now have a slightly used - never had fluid Wilwood 1" MC.
HA- I actually have double vision from my accident years ago!!!
I enjoy looking over your build as well-

Shoot me a email richard454 at comcast dot net. $100 plus shipping it's yours- no box- but have the bleed kit and I have the adapters for the Wilwood to stock OEM brake lines to the proportioning valve. Just need the two fill plugs and the washers (Part#240-8602 $1.99 at Summit)
Thanks!!
That would be great to put a name to a face. Met a lot of forum members on the HRPT
Hey Brent-
Hope you guys are doing alright.
OK-
One big step forward. I have the cooling system all worked out.
Installed the new Dewitts radiator-connected up all the hoses and after several issues- I now have a system that holds over 10PSI for over 30 minutes!!!
I used the steam port to connect the gauge and the port on the upper radiator hose ran pressure, Ran it up to 20PSI and heard the Radiator Cap squealing- then dropped it down to 10-12PSI and let it sit, Sprayed every connection down with soapy water and no bubbles!!!
I did order a 1 3/4" SS 45º exhaust pipe piece-to fit between the upper half and lower half of the lower hose-as I'll use that to route the lower radiator hose at a better angle. Right now it's a little too close to the serp tensioner.
Here's the new bracket mounted- no side to side play at all!!!
Redneck pressure checker..... a black zip tie would look better...
How the pressure is controlled- Trusty old vicegrips
I pulled the 1" master cylinder to replace with the 7/8" and decided I would tackle the small drip I'm getting out of the clutch master cylinder. I check how tight... don't think I can tighten it any more...looks like I've been there done that. A quick Google search- and I'm not the only one with a problem- After looking around I find the best solution is to run a Breeze B9224-0356 Spring-Loaded T-Bolt Clamp.
So next is the oil system- put the pan back on- hook up the new dry sump lines-and check for leaks.
A little bit of wiring to finish up- connect the O2 sensor- and it should be start up time Part Deux!!!





OK- I finally started drilling up my SS sidepipes.
I read where drilling stainless requires more pressure and just keep it cool.
I found the best size and bit to start the hole- was 3/32 Dewalt split point cobalt. After drilling over 50 holes for one sidepipe- only used 3 bits!!! I had like 10 on hand - just in case!!!
So after years of messing with this idea- sidepipes from loud to quiet that will fit under the OEM covers and be able to flow 2 ½" straight pipe- I finally have a finished piece. Looks like it will work- hope to try them out next week.
I have 24 3/8" hole- has the same area as a 1.75" pipe- so some restriction going into the muffler- which is fine.
2½" pipe inside the muffler-
O2 sensor bung
Finished piece-everything band clamps together.
Cut-out motor will be mounted remotely- as there is no place thanks to the frame. I will use a 1/4 drive 90º piece - have the 1/4 flex in the pic
OPEN- loud 2½' straight pipe
CLOSED (and can vary in-between) exhaust will flow through the front perfs through the muffler and exit out the rear perfs. Theoretically the 2½" closed pipe will work as a hemholts resonator....













. Decided to take a break and move on with my backup LS engine. Break is coming to an end (home renovations mostly), will resume the madness in a couple months.(Sorry Richard for the thread squatting).





I'm thinking the straight pipes will not hurt the power- and the slight muffler effect of the perfs when wide open will knock a little bit of sound off.
As far as dropping the level down- If the pipe is half open -It still should flow as good as 2½" pipes. The area in the 4" pipe minus the 2½" pipe is about same.
IF it's not as quiet as I want- I can still add some exhaust packing the last 6 or so inches of the pipe. From what I have read- the glaspac type muffler I used doesn't really have much attenuation after 20" or so-and that's what I went with.
The big benefit will be less heat- as I am shielding it and using different layers of wrap.
Here's what's going around the muffler under the covers-
Here's how I am going to actuate the cut-outs- just use a flex coupler so I can tuck the motor underneath the car as the frame is in the way.
The pipe turn out lines up pretty well with the covers-
In a few minutes I can pull the pipes off - all connected with v-bands.

Oh- forgot to mention the Federal Mogul Thermflex socks that I will put on the pipes next to the frame.
Supposedly used by big trucks around the turbo pipe-made out of baltic yarn .... supposedly work really well...
I got a set off eBay surplus -seconds cheap- they were the right size-
so I will try it out.





I was anxiously awaiting the Fedex -delivery guy looked at me funny because I know I looked like a little kid at Christmas when I met him at the door!!!
Less than 10 minutes out of the box-
I was cutting of the cradle- milling down the aluminum mount to make it fit.
Success!!!!
Cut the cradle- I will weld some flat steel to strengthen it back up
Milled down the aluminum about 3/8"
Clearance -Clarence!!!
A simple AN fitting was all it took to make the Dry sump line go around the rack and pinion-
Way toooooo big to fit- I figured a large sway bar fitting would work-
I found one- should work great and give me the clearance- and looks to be a little more substantial than the original mount.





I'm helicoiling the block for the oil pan- all 40 of them! After pulling the pan off and on several times- I didn't want to strip any more out- after a few got buggered up.Cheap insurance to do it now.
Pan is ready to go- had some stuff beefed up on it- a couple spots looked sketchy.
Windage tray going on
Stainless steel hardware-
Bolt on the pan- connect the oil lines and put some oil in it!!!!
Here's where I am on the electric power steering-
A little- OK a lot of redoing on the column to mount the motor.
Shortened the column a little more- motor is closer to the firewall.
I went with a Speedway motor's column clamp- looks like it will work perfect.
As far as the steering shaft to the Flaming river rack?
The kit uses a convoluted bunch of u joints- supports and set screws.
I'm going with the factory Nissan intermediate shaft- factory splines- factory U-joints and it is adjustable length by design.
At the end of the factory u-joint-a 3/4" DD shaft fits perfect- which will be welded on a 3/4 to 9/16-26 as on the rack. So no set screws- either splined or bolted and notched w/ a bolt.
Here's the column slid together-
Wires for the wiper fit fine
