Typical marketing stuff right? Now fast-forward in that video and watch the time frame of 2:44 to 3:45. And then later in the Part II video clip, they had to build a custom crossmember also.
That right there is a perfect example of our pro-touring build challenges. The marketing and claims don't always hold up in the garage.
For my build, I'm confident I have all the correct components with the exception of the hydraulic throwout bearing. I think I'll buy 3 different ones(GM LS, GM ZR-1, and RAM) and use the one that fits and return the other 2. |
That video really hit home... Lol.
Even the experts have issues making things fit.
I finally did find the right combination of parts to mate up a T56 Magnum, ZR-1 Twin disc clutch, GM ZR-1 hydraulic throwout bearing, and Quicktime LS steel bell housing to fit my 69 Camaro with a Gen IV LS engine. D&D Performance makes a machined aluminum spacer 0.980" thick that goes between the T56 trans and the QT bell. With the spacer the ZR-1 throwout bearing fits, and the input shaft on the trans slips into the pilot bearing about 3/4". D&D had the part on the shelf so this must be a common issue.
I don't know if these numbers will help you to figure which throwout bearing to use for you set up... but here are the dimensions I ended up with. The total depth of the bell and spacer on my set up is now 6.53", the ZR-1 clutch is about 4.13" thick (from the back of engine to the fingers on the clutch). With these dimensions the ZR-1 hydraulic throwout bearing works. For the pilot bearing I used the stock LS pilot bearing that presses into the larger bore on the end of the crank.
Goodluck with your install
