Did the motor just turn over when you tried to start or did it make any popping or backfire noise? Also your car is a 98, if you're still using the 98' coil harness, you have to make sure the the LH & RH harness are not swapped.. The car will not run if they are.. The pin-outs are different from 99-02 models that can be swapped. If you still have your factory rocker arms, I would throw those back on & try again.. I can't see 7.4's being to long on un-milled 243's.. I run 7.425's on my 243's with a much larger cam.
