thanks ron. i will give you some feedback on the pro mod comparison. i am going to run the one i have side by side with the B5 so i should get a very good comparison.

glad to hear about the 14t bell working in my MBX6T. actually that is what i have mounted already and was hoping it would handle it!

i am assuming the OS P3 would be a good choice of plug? seems like it from this forum.

this is a great forum for this motor. i race around the midwest and there is not anyone i know of running the B5 in my area. that will soon change once they see it ripping around the track!

thanks to all and ron for the info.
