so as far as billet heads go is the hpd cool head with the aen girdle kit the preffered setup?

 

The HPD head has the girdle built into the head. The Aaen girdle is for a stock head.

 

it will deliver less power on PUMP gas for sure,mine dynoed at 77+ hp,
that just reading for one good day,the more timing advance you throw at it with high octane gas=more output.

 

I assume that is at the crank?

It is called a new baby and new house....ha...I just sold my bike up the river and it should be running at a track in Va this weekend. I will let yall know how the guy gets it going. I only ran it one time since the rebuild, so hopefully he can put some time on it and get the ets low.

 

yes at the crank for sure,and this summer with a 165 main jet during
very hooter temp i got near 80 hp with my hpd race mod/wiseco connecting rod motor on 110 race fuel at 76-7700 rpm,
i really say,those thing turn far away from stock engine with proper
reinforcment parts and welding case.

 

That will do it for sure.[img]i/expressions/face-icon-small-wink.gif[/img]
