tranny slipping?
 

i just freshened up my 318, bored .030, 489 lift cam, carb, intake and such and i went to the track tonight. i have a 904 tranny and it is on the column. it pulls much harder when i manually shift it but when i shift it seems to stall and rev up between each gear and it is kiling my 1/4 mile. does anyone have any ideas.
