Very nice work! Glad you took pictures since it will all be hidden once the car is back together.

ECM and Fusebox Mounting
 

I started out playing around with a flat pattern to mount the ECM. My MSD was already in this location so I just sort of changed it around to fit the GMPP ECM. Made a few paper patterns and then one in metal. I reused the vibration isolators off the old MSD.

The fusebox mount is pretty much flat, except for a little pickup point for the round hole in the fuse box. I used the old battery tray mounting holes.

I probably wasted too much time making the little hold-down clips. I know they can be purchased already made and of course they are thicker and better quality. But it was sort of a challenge to see if I could make them.

Overall I think it came out about like I expected.

Before long I will be ripping the harness apart and planning all the wire routes. So it will be nice to have the box and ECM mounted to support that.

I just started receiving my stainless exhaust pieces and mufflers. All the oval tube and transitions are on order. Next week I will get started on the exhaust which will take probably 5-6 weeks at my pace (or more). I need to order a driveshaft this week, or I won't be able to route the tubes properly. I also need to figure out the back-purge for my TIG welder.

Nice fab skills! Good progress!

Some great work there.

Exhaust parts received from Burns
 

This is a short mid-week update. I received all the exhaust parts from Burns, up to the mufflers. I am looking forward to getting started on this but I will take it slow to avoid too many mistakes. I plan to get the easy part done before I go up and over the axle and figure out how to cut the trunk area. I have lots of extra straight tube so I will probably practice a little before I get going. The plan is to figure out and tack up the transition from the headers and get started on the cross-over this weekend.

I decided to shamelessly copy the cross-over idea from the J-Rod 68 Camaro. I think this one looks really nice.

no shame in wanting your exhaust to look like that.
I absolutely love all the parts going on your car, you have a good way of executing all the details to boot.
keep at it , you give inspiration.

Thanks for all the kind comments. I didn't get any car work done this weekend but I cleaned the snake pit of a garage and put the car back on the rotisserie (finished adjusting tonight). Dang I am getting too old to do that by myself !!
I will plug away at routing the exhaust and also the fuel line while it is easy to work on. Looks like my pickup will spend another hot Summer outside. There is just no room for a second car now.

This is such a cool shot, car looks awesome

Exhaust Cross-Over
 

I got a pretty good start on the exhaust this weekend. I had Friday and Monday off which helped. I ran a few errands and got the back-purge setup working pretty well on Friday. I spent a few hours practicing. The purge gas works great with good clean welds on the inside of the tubing. My outside skills are weak. I need to practice a little (lot) more before I do the final welds.

I picked up this (Fupa 12) for my torch. I like the added visibility. It seems pretty sensitive to a light breeze with all that open area. Jury still out whether it will help me or not.

Once I got the headers back on the car the transitions were pretty easy. They were a good confidence builder.

I really got schooled on the cross-over. The basic pipes were not that bad. I got one finished and then just made a mirror image. Getting this far was also pretty easy. First one took a while second half as long.

I don’t have a band saw, or good chop saw and it took a long time to get the cross-over worked out. I finally just had to free hand all the cuts, after a failed attempt on my cheap chop saw. That was ok but crooked cuts cost me a lot of sanding time and I wore out two flap wheels. I still have some fine tuning to do.

I put the mufflers up and it looks like I will be able to connect them pretty well. I still haven’t figured out the hangers. I was hoping to have that completed but didn't quite get there.

This week I will try to get the mufflers roughed in and get the tail pipe pieces on order.

Nice work!
