Do not use a 509 cam in a low comp engine you will make the car a pig I would concentrate as stated on heads and engine dist running all the total I could get the car to run/ start with in normal fashion Run a hyd cam of around 480-490 lift keep the centerline at around 112 Good intake and exhaust If you can try a 350 horse from late 60 early 70s still around and cheap if still in a car. Do not pay any attention to the Mopar bible for total timing limits of 36 or so Give the engine all it can take and back off when she barks. Run a 650-750 dbl pumper 650 for throttle response 750 if you can for overall power and drag racing.
Have fun and just do it !
You dont think 509 cam even with 4.10 gears and 3000 stall?
I ran a low compression 440 with a 509.
Don't do it.
The car was an absolute pig down low and only mediocre in the mid range and above. We dropped a 484 cam in a low compression 400 and that Road Runner was much quicker than mine.
