Truthful advertising

Nothing like it.......... .

Keep it up, Brian. You might have to start designing frames for those engines just to hold all that power!

Thanks so much but I have to give credit to my staff. I just make a feeble attempt. That motor is in an almost daily ridden Duece!

131 rocks!!!

Hey Brian,

This is Ed, Darryl's brother in law. The 131 combo that you provided to Darryl just plain out rocks at 145hp and 160ft lbs with California pump gas. I'll be calling you soon for a killer combo for my bagger too!

Can the Jims combo be made into a 139 with your 4.25 barrels?

Ed

Sup Ed!

Glad to hear you dug it! We have a new kit for the Jim's 120 that takes it out to 135" with a 4.375 bore cylinder. Check out our new billet cylinder heads at www.revperf.com! Tell D.W. to call me next time you talk to him!

'm out,

BN

The easiest is the 98" kit. It is truly a bolt on. No need to remove the engine. Best thing to do is give them a call and talk to Brian or Scott.
