Circle R racing (BOSS429)

I want to thank Rich @ Circle R racing for helping me build my A441 hemi headed motor. Rich really knows the Boss 429 engines and is a great resource when builing one, I encourage anyone building a Ford hemi engine to get in touch with him. His tag name is BOSS429 and is a member on the forum. My engine came back from dyno with north of 950 hp on 92 octane pump gas. ( I am not going to disclose the build specs but Rich knows them) I am currently working with Rich on a nascar Boss 429 engine for street use, I am a rookie at building high hp engines and Rich guided me thru all the tough stuff over the phone.

Now I have to stuff this engine in my T-bird for racing season ( no high dollar race gas this year)

Thanks...
Denny

Rich is a smart cookie ....... but we need pics

Good idea Bruno! Sorry about the big pics.

Thatsa big motor can only get half in tha pic j/k looks good wish I could afford a hemi.

Me too, but I guess if they were cheap, everybody would have one, and they wouldn't be special anymore.

damn it man ..... im only getting half of that engine porn !!!!! thats gonna be a bad mama jamma , keep us updated on the times on the car

BEEEEYOUTEEFULLL !!!

Denny,

Nice engine,nice dyno numbers and nice T-Bird.

Later Mark.

Congrats Denny

It was a good idea only sharing half of that engine with us, because there are several of us who couldn't handle the whole thing at once. I was drooling over the half shot and got dizzy and fell off my chair the way it was. It's OK though, the wife brought in some race gas and revived me. I'd probably be in a coma if I would have taken in the whole thing.

Sorry Guys, finally figured out how to resize them!

Denny

Hey I know that guy. J/K Engine looks great congrats.

Man them heads make that block look like a 302. Nice piece!
Bob

I wondered about that a s well.... How long are they?

its all in how the manifold was made. it looks short,and it is by most std's. But most important this engine really likes it.

These boss motors are almost like cheating they make so much power. A friend of mine built a 547 this summer for a customer, 10.2:1 street motor with Kaase heads and intake, mild street roller and It made 875 hspr.

That's the important thing. As long as it works, who cares how long they are. It certainly looks like a nice manifold. Did you guys fab it or who did?
