Converter should be here this week. About to order motor mounts but can't find the GM or an accurate ARP part number for all seven for each side. (3 for mount to frame, 4 for mount to block) Anyone got a good part number or source to use? Seems everything I find it for LS "swaps". GMPARTSDIRECT doesn't list the bolts, just the mounts!

 

Both are M10x1.5 bolts, probably 30mm long.

 

What mounts are you going with?

 

I'm going to end up going with the Atomic Poly's, but for now I'm going with the stockers just to make some progress. Money and time are both super tight right now and as stupid as it sounds, I would rather replace the mounts later with the good stuff rather than have the project held up another 3-4 weeks while I save up for the Atomics. I just need to get everything in and start bolting **** together instead of collecting parts and sitting on a dollar waiting on a dime ya know?

 

Yep, I know how you feel. I still need to upgrade mine, I want to go with atomics myself. What exhaust you running?

 

Running American racing headers 1-7/8" with their 3" y-pipe 2 into 1 into a Spin Tech 6000 series with dual outlet. Probably going to kick them out before the tire.

 

For the first time in 4-5 years, the engine is in my garage and ready to drop in! Waiting on a couple little nuts and bolts and we will be ready to put her in her home!

 

Oh boy! Get to work!

 

Working out the little fitment things and whatnot. Getting staged for swap time!

 

Got ready to mate the trans to the engine and realized the measurements weren't adding up. Had a perfect 1.050" from trans case to converter bolt flange but had a 1.300" roughly from the block to the flex plate mating surface. Did a lot of digging and back checking and realized I have the elusive long snout crank and the TCI flexplate is made for the short snout without the need of a spacer. SOOOO..... another weekend lost while I searched for the right flexplate. Unfortunately, the only one I can find is a GM Perf OE 4L80 one. Fingers crossed it will hold up. Waaayyy too late to change the crank now!

Side note, anyone need a #399754 TCI 4L80 SFI flexplate? Only bolted on once, 0 miles, LOL.
