My 65 Lemans LS1 swap.
Bought this 65 Lemans off CL Dec. 2015. Solid car with all new interior, new tires, new exhaust, 3:73 posi and 350 turbo. Motor was absent. I have really enjoyed my LS1 powered 64 Tempest so decided to do it again on this 65. On the 64 I used BRP Hotrods pricey motor mounts and headers. This swap I am using adapter plates with Chevy motor mounts and the stock LS1 F body exhaust manifolds to save $$. I purchased the LS1/4L60E complete with all accessories, wiring, ecm, fans and battery cables out of a 99 Trans Am with 114k miles. Price was $3400 delivered to my door. The first thing I did was remove the front clip to make installation easier. Next I removed all body mount bolts except the rear ones. Those two I just loosened. I have found it easier to raise the front of the body to make engine/tranny install easier. I will replace all body mounts before bolting body down. Next I removed the original F-body oil pan and installed a GM performance oil pan part number 19212593. Cost $194. I replaced the front seal in the transmission, reinstalled the torque convertor and bolted transmission back onto the motor. Getting it ready to drop in the car. Will update as I progress.
Cost $3400 LS1/4L60E $194 oil pan

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
