Awesome build so far! I did this basic conversion on my 1969 C10. I will be honest and tell you i completely rebuilt the 5.3 iron block and damn, the design changes from Gen 1 Chevy blocks is great! Everything is O-Ring gaskets, fitiment is perfect, the crank is in with 6 bolts, and so on. Anyways, nice build, you will love the LS.
I will say this, i used dirty dingo motor mounts and when the 4L60E was in, my drive line to Tranny and Rearend angles were way off! I had to add 1.5" aluminium block to the tranny mount to get them to a decent angle. The tranny was pointing down at 13 Degrees. It could be the motor mounts, either way i had to install a High Hump cover to get enough clearance. Good Luck on this, ill be watching for updates.
Now i am off to go work on the next project, my 1966 Factory shortbed fleet.
