Hillside 124 dual cam

[mayor]

The dyno run was in fifth gear from 2500rpm to 8500rpm it spun the drum to 152mph in 2.4 seconds. Here is some of the spec's ; 120 cid. about 1.7 hp per cubic inch, 4 3/8" bore , Static comp. 16:1 , CCP Front 320 lbs. Rear 316lbs. 8" knife edge flywheels, aluminum rods, the cam that's in it now is a split pattern .806" lift intake .800" lift exhaust I won't give any other data on the cam, dual 50mm Fast By Gast carbs, Billet heads, Titainium valves, titainium wrist pins. I have over $30,000 in the motor.

wow, that's far from run of the mill there.  In all seriousness, I think you earned this:

[Hillside Motorcycle]

Our 108" AHDRA racer with House of Horsepower cases, STD round-port heads, .813" lift custom ground(to our specs)by Comp Cam, 4 3/4" arm/3 13/16" hole, Del West titanium valve blanks, S&S Big Twin wheels turned to S&S XL race wheel diameter,(they never shifted/sissored/slipped) thinned/knifed(here) Carillo rods, J&E blank top pistons machined here, with tapered-wall tool steel wrist pins, to set it at 17.25 cr, would BURY a Snap-On 350 psi compression guage, with our Double B S&S carbs, 2 Thunderjets each, cross-ram set-up, and 2 3/8" custom in-house pipes, would blow through a dyno pull in a little under 2.8 seconds from 3500-7300-7500 rpms.
Might have $7500.00 in the engine. Much more time vested, than money though.
That is what those do, and that is what they are supposed to do.
Friend of ours 114"(5 x3 13/16) Iron XL AHDRA bike would show about the same.
Again, no revelation whatsoever, as that is the total intent of that engine/bike/gearing.
