SN 2000?

[89gtvert]

I just completed the SN 2000 install on my 89 gt but have not fired it up yet.I wanted to know if I needed to change the timing as per paxton instructions on the 8 psi kit since I have a msd btm installed,cant I just dial away timing with it instead of actually timing it ??.I have a 306 E303 cam,TFS heads ,1.6RR,Cobra intake,JBA headers with full exhaust,255 fuel pump etc.

Yes, you can, until the BTM craps out and leaves you with 36* total and blows the heads off.... Not a big MSD fan myself. If everything works, you can do that, yes.

I have never had a msd fail,but as you stated im sure it happens 36* WOW!.I appreciate the response and will always have that in the back of my head now...thx alot.

Just do the math using the BTM to give yourself 19* total at WOT using 91 octane if you see 8psi.
