Title: Boss 547
Post by: Royce on February 20, 2022, 04:02:35 PM: 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

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.

Post by: machoneman on March 13, 2022, 07:39:32 AM: 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?
