hey guys, i own an 85 bronco Ive had her for 3yrs. Wen i bought it, it had a bad lifter. So i changed it, now i have recently done sum subtle changes due to a bad cam and the same lifter problem. changes are: slightly bigger cam (lift 290 int 293 exh. lobe center @ 115.) all new ignition components, double roller timing chain, headders, dual flowmasters ( no cat), new lifters and pushrods. Now for the problem, she starts, idles and revs nice. but once its in gear it misses and fidles erratically. Im hoping that my sd computer isnt the problem. Anny suggestions or advice would be enormously appreciated. Thanxxx:goodfinge

Im pretty sure it is, Ive checked it multiple times. As for the cam, its an isky cam custom ground to match stock mustang H.O roller cam. But mine is a flat tappet. I have all the specs: int duration 262 lift 290. exh duration 272 lift 293. @ .050 int. 208 exh. 214. and the grind is 373 int 353 exh.
