Boss 547

[Royce]

This is a little out of the groove here for this forum but thought it may interest a few..

I had purchased a Kaase Boss 9 kit for a 460 block a while ago.. It has been sitting in the corner for a while waiting to be dynoed.. All the parts were specd by Jon, I wanted a engine that could be run on pump gas if necessary so only about 11:1 compression . He picked the cam so it would result in a low maintenance valve train. I built a set of generic 2 inch primary dyno headers.. It is a single 4 for a Dominator. Dyno shop's 1250 was used

I was estimating 750-800 horse.  I would have been bummed if it was favoring the 750 number. I need not have worried

840@ 7000 698@5300

Very cool, and what my 70 Mustang should have in it if the owner wasn't a cheapscake with a bunch of FE parts on the shelf

Very nice

Congratulations, that's a nice piece.

Last one I did with his B9 heads was a 528ci engine.  Very mild hydraulic roller, 10:1 compression, and a 1050 carb.  It made 750 hp @ 6000 with 700 lb-ft.

very nice, do you have picture of those good looking valve covers on the pump?  would that fit in a 1936 ford coupe?  lol

[Royce]

Here you go.
I am not the good looking one

[gdaddy01]

Amazing results Royce! 1.53 hp/CID in a streetable engine is smokin'!

But, is even a 2" header big enough for a big CID Boss engine?

Very nice engine.  Could you give more info on the heads (as-cast(?) port volume, cfm, valve sizes).  Thank you.
