Could you measure the distance between the bellhousing and the radiator support? Didn't realize you are using an auto. I was thinking about this today, and figured I would use the subaru flywheel and machine a crankshaft hub and adapter plate. Looking at the engine bay, I think it would be very tight, but maybe possible if I was to use accessories from an 5.3 Impala SS.

I'm very interested to see how you mate the v6 to the Subaru tranny and how the starter, flywheel, and clutch will work. The v6 uses the same bolt pattern as a SBC, right? How much room will you have in front of the engine with all accessories installed? Is a LS1 possible with the stock trans? I have been seriously contemplating this and have the mechanical and electrical capabilities to make it happen. I know it would be tight, possibly having to remove the front bumper beam and modify the radiator support to move the radiator and condensor forward as much as possible. If I can fit it under the hood and keep the awd, it will happen as soon as I find a beater car.

I think what you are doing is great! I'm a die hard GM tech and love the idea of a GM powerplant in an LGT. Good luck with the swap. I'm interested to see how well it fits with the Subie trans. I have an L33 Chevy truck motor (all aluminum 5.3, 310hp/345tq stock) in the garage that I've been thinking about using when the 2.5 blows- it will. But I was planning on using a T56 trans and rwd only.
