You know the world is ending in 2012 so you need to make those dreams come true.

I started a small side business 6 years ago to fund my dreams.  Now I am starting to gather parts for my next come true dream - the '32 Deuce roadster RAT ROD.  But it looks like it will not be finished until 2013. :-\  Damn those Roush engines are expensive!

Art,

It's been a somewhat boring and uneventful winter without you and Seaweb  ;)

Have you thought about picking up a used Roush Nascar engine?

Do you have a final $/HP (dollar per HP) figure?
As of today 3/13/2012 my original owner 75 CB750F has made it through 3 wives, er EX-wives. Free at last.  ;-)

The shocks are YSS Z-366 TRL

They are a bit of overkill, but so is everything else on the bike.  ;D

My wife nicknamed me "overkill" when we met 10 years ago, because she believes that anything that I fix, install, build, buy, modify, research, or just do is done to the extreme.  I however think that this is only one way to do things.

I never considered picking up a used Roush Nascar engine, I may look into it.

Final $/HP figure = PRICELESS

 Geez, I though you were really going to build something that runs great. ::) Only a 30+ HP gain, like why even bother. :) I was happy just to get mine running good and your just taking all the thunder. Excellent job Sparty. 8)

i think my favorite part of the hot rod , is the that you got the carpy gauge faces, ... but not the ones that say "cafe" on um ....        i didn't even know carpy did that until your bike



and yes ,  a Deuce needs a flathead , (or a Rocket)

I'd say well over a 40HP gain as the stock 750 is lucky to have 50HP to the rear wheel on it's best day. Over an 80% increase in rear wheel HP with only a 14% increase in capacity....that's the important part.

Okay, calculator is in hand, going though costs of just the engine build....  looks like $77.00 per HP.  Damn, now I see just how much money it took... still PRICELESS as few others have what I have.  Now, I am figuring the cost of the 32' Deuce Rat Rod $/HP.  Let's see... I would like a 500 HP engine so..... looks like about $90.00 per HP.  Heck the CB HOT ROD is a bargain. ;D

Even based on 65/67 hp at the crank a 30+ hp increase is nothing to sneeze at in my book. Plus the added reliabilty with the upgraded studs, chains,blanceing<sp? and the quicker reving abilty gives him one hell of an overall increase in performance across the board. I figure next year we might get a better idea just how much he can get from all the work that has been done. If he can afford the tires he will go thru. And yes I'm jealous. :P

Yep. He already put the bike in the 11's if I remember correctly and that was on a cold track and it was his first time doing it. ;)
