The L31 is the last version of the old 350 and I think it the best most improved version. I like the old school look of the 350 but a low mileage ls would be a good motor also.
I chose the L31 for all those reasons and more. I'm running mine with a Quadrajet and HEI. With a cam change (HT 383 cam) it's good for around 330 horses and close to 400 lb/ft of torque.
