318 stalls in Drive

I would pull that cam in a heartbeat. Get an rv cam and lifter kit from Summit and a timing cover gasget kit and intake gasgets from local auto parts store for all around 150.00 a .484 purpleshaft in a stock 318 never works out right. Nowhere near the right compression for it to run correctly, plus a stock, low stall converter, 6,000# truck, 4wd... just wrong on all accounts. Change the cam and be done with it.
