Re: Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread
Thanks for the clarification. If you are planning to enjoy aggressive throttle stabs with your truck following your swap, be prepared to have to swap out those rubber mounts rather quickly. I’ve seen them last as little a 3 months behind a mild 5.3L LS engine.

Uh oh, now I learn that after fighting the install for half a day. No, wont be aggressive but don't want to go back in a short time. Sort of like having to replace the drive shaft center support bearing due to inferior rubber each year...going to go single piece now that I have the opportunity.

No throttle stabs, but I did notice they quickly allowed the engine to settle a bit and cause contact between the oil pan and steering link rod. I went ahead and switched to the urethan mounts while I had the engine out for replacement.

Also, I finally checked driveline angles and removing the spacer from the trans mount made the angles much better. I have a 71 long bed with 5.3L Vortec and 4L60E. Diff is a bit too up, but close. How do you change diff angle on these trucks?
