Well its tune up time on my 1990 vert so im looking for some good experiences with certain tune up parts.i just changed the intake gaskets and put in bosch 3 fuel injectors( the bosch 3's have made a big difference in performance) so im looking to do a major tune up.Tell me what has worked great for you and what didn't.im looking at an Hei distributor and rotor(was thinking MSD cap,rotor and wires) also replacing the plugs with an oil and filter change(prolly go mobil 1 engine oil but what is the best oil from mobil 1). Any suggestions on plugs or anything else that I might consider...Thanks
