Actually, thanks. Been running the LS1/4L60E combo now for almost 2 months. I went ahead and dropped in the LS1/pump unit assembly (although its been extensively modified) into the stock '73 tank and used a 3rd gen sending unit. Also ran the entire 4th gen HVAC system... That wasn't an easy task.

I must say, I have no more doubts after tonight. Took the converted '73 out tonight to the track and clicked off a [email protected] cutting a 2.2 60 ft using a STOCK LS1 with a STOCK 4L60E with 3.08 gears. Just has full exhaust and a custom intake tube setup for it, and the car has not been tuned for the additional airflow. It hits the rev limiter slightly on the 1-2 shift. Car weighed in at 3440 with 3/4 tank of fuel without me in it. Power windows, 8 way power seat, tons of sound deadening, air conditioning, sway bars, heavy 17" TT2's etc etc. Car was raced as is driven everyday, didn't even air the tires down. Got a ton of positive comments and questions on it tonight, was a real showstopper in the staging lanes.
 This car has EASY 12's in it with some traction. Pretty stoked.

That's so cool.. You did good Ian.. That project was a big one, and you did a fantastic job.
I have no "Chevy/Pontiac" issues with the swap.. It was a great Idea. Kudos...

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.
