MSD box or not with Fast XFI

[Motown 454]

I just bought a Fast XFI for my motor. 454 SBC stroker 600hp. My shift point is 6600 rpm. Will I gain anything with an MSD 6A box and this system? I was thinking the 6A because I don't need the rev limiter , the XFI will take care of that. I plan on using a Fast dual sync distributor. The car will be 99.9% street driven but I'm in over my head already so I might as well do it right the first time.

Another question is . I have 42 lb injectors (Their used but I will have them cleaned and checked) they should work for my engine ,but I was told be a tuner around my area. He would rather see 48 or 50 lb injectors on my motor. I was wondering what the opinions on this board were about it? Can I boost my pressure up or just get the bigger Fuel injectors? My pump is capable of 95 psi.

I started getting my fuel system together. I have a Weldon 1100A pump 135gph/0-95 lbs with aeromotive 100 and 10 micron filters and an Aeromotive 13109 fuel regulator . I'm going to run 10AN hard lines from an aeromotive sumped stock tank to a Y and bring the hose down to 8AN to the rails then 8AN to the regulator and 6AN hose to 6AN hard line back to the tank. Opinions welcome
Thanks Wayne

Are you going to run sequential? Assuming you are since you are using the dual sync, I believe you will either have to run an MSD box (for points output) or crank trigger.
I am using the XFI with the fast dual sync and a msd 6 box... nice setup.

I just picked up an MSD 6A box to go with my XFI. I've been having some luck finding parts for the car at reasonable prices. I also got a killer deal on a FAST 1375 cfm TB . Now I need a coil and a FAST dual sync distributor.

I'm running the MSD 6A and blaster coil on my 427 SBC with the XFI and Dual sync and the spark output is great.
If you have not already done so read my Dual Sync warning a few posts down.
