its actually not a 5.0 in the automatic car....brother's 67 coupe. its an early model 302 with 66 289 heads that have just been shaved and 351 valves installed. i agree that a 5.0 block wouldve been better with its forged pistons and roller cam, but his heads are actually better than 5.0 stock heads. i guess 145 psi isnt good compression? we were afraid when he did the heads he'd got a lot of blowby/blue smoke, but none at all. we are going to the track again tommorow to play with the timing, see if it runs any better. its really weird that this thing pulls so hard in midrange/top end and will not even get rubber at take-off. we were told that his low torque motor on a 3k-35k stall converter would stall at 3000 because converters act differently on different motors. this is a daily driver car so we cant get crazy, but is a 2 second 60ft time too much to ask for? i think if he could launch around 2500 it should be perfect because i was launching at about 1500 to 2k in my 4 speed car on those same exact tires and getting a 2 second 60 ft. SEE, THATS WHY IM NOT AN AUTOMATIC PERSON! does everyone agree on 2500-3000 stall for this setup?
