finnally i got it running right somewhat!after swapping my valve covers thinking that a rocker was hitting (whoops loose rocker) i figured what that miss was finally i sat down started it up and vroom that favorite mustang sound.now just te fine tuning has anyonehad this problem after the car is running for a bit yourev it once and then a quick rev right after the car backfires through the intake? also my base timing is like almost 20 degrees no pinging either at all spun the balancer maybe? i have no bottom end at all i think thats bc of my heads though they are ported and flow more then victor jrs which is fine i guess bc i have an s/c going on soon. the car breaks up at a steady speed with the msd connected which i just think that the wires are bad not sure.but from about 2500 all the wayto 6500 the car pulls like a mofo it feels like it can go way more but im afraid as i still have the stock injectors f/p and maf. i have new stuff just waiting for the sc to go on first just wanna get it tuned right till next month for the rest of the stuff
