Re: 49 ls1

So I decided to mock up the 5.3 in the engine bay to see where I was at, and where I'd have to cut. I mounted it about 2 inches higher than I would have for a 350, so I can use the stock pan. Since this truck will get bagged, I don't want anything hanging below that crossmember.

Initially I had about 3.5" of clearance between the wp pulley and the rad. I'm looking for about 5". Rather than buy a different accessory drive, I decided a 2" recessed firewall was a good option. So I made some rough cuts, bolted on the trans, and blocked it in position.
