I don't know anything about that kit but I do know that Steve from GMR Performance has an excellent 113" kit.

I know these guys have a good reputation and I'm not bashing, but $6k for a gear drive 113" with no bottom end work, no pipe??? Not for me!! For only a couple of grand more (peripherals, pipe, tuner, TB etc...) I'd go S&S 124 Crate...

But I guess that I could brag about a 140 hp dyno sheet. (at least for awhile :nervous:)

I like GMRs curves much better...

While I have repect for George Bryce & Star Racing, I've never seen 140 hp from a 113"..........at 10.0:1 compression.

Having owned several 113" variations from 10.5:1cr to 11.0:1 I can tell you 135hp from a 113" isn't easy.
