Hi ever one I have just done a 430 rebuild and installed a bigger cam. http://www.taperformance.com/proddetail.asp?prod=TA_212-455&cat=153 Now the car stalls when put in gear at normal rpm. I have a new Holley XP 750 on it and had a micanic look at it . He suggested I may need to put a higher stall converter on it. It has the original stall converter on it ( possibly a switch pitch but all the switch gear is missing). Please help.
