Default Motor is Finally back in the Firebird

Got the 535 in the car finally. Still have to do some work to get it running.
* Hook up fuel system and carburetor
* run the oil line to the new pick up location at the front of the block
*hook up cooling system
*Finish the new exhaust. I spent today making adjustments to the headers to get them closer to the floor and create a little more ground clearance. Also finished the exhaust from the collector to the X crossover. I had it on and off many times adding pie cuts to tighten up clearance. The 3.5" exhaust will be about 1/2" higher than the 3" when I'm done.

Work is crazy for the next 2 weeks, coming up on inventory...hoping I can find a few hours here and there to try and get it started next week. Then I will finish the exhaust and the new rear shock cross member.

I sure hope so. I worked on it a few hours Monday morning, wouldnt start. Checking for spark and there was none. Checked the MSD box, appears fine. I have a replacement crank trigger now, hoping thats the issue. My biggest problem is finding time to work on it.

Im going to stay with my TranSpecialties 9" for now. Try it and see where this motor pushes the converter to. It flashed to 4400-4500 ish behind my 474, that will give me a starting point. Then if im not happy with the slip % or how it acts I think I will call T/S for a recommendation. They were pretty good at spec'ing my current one.

I spun a bearing in my 474 last December. At the time I thought the 535 was really close to just dropping in the car. But there turned out to be a lot of little things i wasnt thinking about. And I decided I wanted to dyno it first. That took a couple months to actually happen. Then I Hurt a couple rocker arms while on the dyno. That took a couole months to get the repalcement parts. Now its in, started it this morning ( my issue with no spark was related to the start regard controller ) So now I'm moving on to try and finish the exhaust and re uild the rear shock crossmember. I imagine if I could have devoted more time to working on it I could have trimmed 2 months off the timeframe.

please splain me......

Finish the new exhaust. I spent today making adjustments to the headers to get them closer to the floor and create a little more ground clearance.

????
cutting/welding the tubes? or some "other" ways? It would be nice to tighten my Hustlers up to the floor a bit

From the manufacturer the collectors were made to angle / aim downward. I made a couple pie cuts and rewelded the collectors to angle them back up. Had to do both collectors but not exactly the same, the passenger side was lower than the drivers side as they came from manufacturer. All the work only gained me about 1/2" ground clearance. But thats at the collector, and it has scrubbed the ground before on speed bumps and poorly angled driveway/entrance ramps.

Thanks, I'm pretty happy with the way the exhaust looks so far. I angled it and added short bends in a few places VS. my old 3" to gain ground clearance. Its about 1/2" higher and its 3.5". The damn mufflera didnt come with offset inlet so they are at an angle but I should be able to make the tailpipes turn and exit where I want.
The driveshaft loop is similar to this one by Lakewood.
Lakewood 18000 - Lakewood Universal Driveshaft Safety Loops
I dont know specifically who made this one. Ive had it forever.

My cousin put a long/large dia pipe in the header collector and bent it upward.

Did he have to use any heat or just applied pressure.? Also remember if using this method, you will have to bend past where you actually want it to be. Metal will flex or spring back a small amount.
