I currently have my Rappy's engine out being built and I'd like your opinions on what changes to my combo, if any, I should make before I give it the go-ahead.

11.5:1 105mm J.E. piston (727cc)
Carrillo connecting rod
Stage II Hot Cam
Kibblewhite valve spring & retainer kit
Full port and polish
31mm intake valves
33mm exhaust valves
HD clutch kit
Hinson clutch basket
"02" tranny upgrade
Graydon Proline pipe
Stock carbs (for now)

Any changes I should make? Any guess on final HP figures?

 

I would have the crank assembly dynamic balanced. The hp will depend on the port work and if you change your exhaust.

 

Good suggestion on balancing. I take it that you don't like my choice in exhaust?

 

I'd go with a megacycle cam and all the same valves for more of a even flow

 

Only problem I see is that you are trying to re-use your stock carbs. Not going to flow enough fuel.

Now I have a question for you.
How much do you plan to spend for all of this?
my estimate would be around $3500! Plus transmission
In my opinion your reliability will be greatly diminished.
HP should be in the 60's
good luck

 

You're pretty close on your $ estimate. Carbs will come when my wallet recovers.

 

Thank's, I'll look into the Megacycle cams specs.

 

I would hate to see you burn up those pretty new valves from running lean.LOL Personally I would wait until I could afford new carbs to start. But that's just me.

 

The exhaust will work fine but it will probably make a lot of the power down low and will effect the hp number you end up with. It all depends on where you want to make power.

 

where do you go to find out about mega cycle cams
