800 (or near it) HP for less than the price of a 600HP FE crate.

I have all those parts that I can strip off my existing engine.

In fact I would have them delete the oil pan, water pump, intake manifold, carburator, and distributor and see what that does to the price.

I think I may be seeing my Christmas present next year, and Winter project.

Don't wait. Make it your Easter present.

Oh- and post it all on here.

Correction
The Boss 9 win at the 2009 Engine Masters was stated to be 3rd place. That is incorrect. It was actualliy third in 2008, then sixth in 2009. Kasse debated about entering the 2009 Boss 9 because rules that year favored a small displacement, out of the lower range of Boss 9 performance. However, this is for extreme race condtions - You can still build a fine street engine with these heads.

The post by Don seems to imply that the Boss 9 won in 2009,which it did not. The winner ( !st ) In 2008 and 2009 was a KAASE CHI Cleveland with something like a 1/4" copper plate head gasket to clean up the geometry

Probably could have skipped this, but I need to pork up my post count..........

Good to see you-keep coming. Wasn't it '07 when Jon finished second (by 1/2 point(?) to Bischoff-with a Pontiac???

John , intent was not referring to any specific engine, even though that was the topic subject, only that Kaase participated, part of the overall subject as an additional reference

When putting my kit together the Cammer was my first choice,Boss the second,settled on the 385 and very pleased.

In the 2007 Masters I think Jon lost by something like a half dozen points.

There was a more important outcome of that event. Jon does not like to lose. and was feeling a little down on the trip home. He decided he needed a new project, chose one he had considered since his early days in hotrodding - build updated BOSS 9 heads. So, if he had won the Masters competition, left in a cheerful mood, the BOSS 9 project may still be on the shelf.....

Kaase called yesterday evening while driving home - He had been playing with the newest version of my BOSS 600 on the engine dyno. The same basic engine as the 980hp pump gas version described above, but runs on unleaded race gas and has substantial head modifications and porting - still a single FB carb

The results?

1,088HP at about 6800 rpm

I think that will be enough for now - time to get back to the chassis construction so I can drive it someday....
