Do you know anything about the Pontiac head they are doing? Also have you done any work with their Chrysler head yet?

I've done tons of stuff with the Chrysler head. It works very well. Getting 365 cfm with only a 300cc port and stock pushrod location.
Tha Pontiac will be very similar to the Chrysler. I work pretty closely with Bulldog as they are only 5 minutes from my shop. I'll keep you guys posted.

Has there been any more development work on the oddball heads like the Olds, Pontiac or Buick? Just curious.

The Olds heads are making good power. The PHR Engine Masters challenge showed us that. We did a basic off the shelf set and made 600+ HP with a 400" pump gas engine.
The Buick stuff is flowing just over 400cfm and should really wake up the older engines.
Still waiting on the Pontiac stuff, but it's coming soon.

Hey Mike
Next Saturday some of us oldsmobile guys are getting together for wings and beer. We're suppose to meet up at Bulldog Performance and take a tour through the facility, should be pretty cool.
Thanks
Kris

Yeah, Bradshaw called me. Too bad I'll be in Alabama racing. Wish I could have been there. If something changes you can count me in.

Hey Mike
Just wanted to say I enjoyed my time talking with Bradshaw. The shop was not what I was expecting, never realized what it took to create a cylinder head. Bradshaw was extremely gracious with his time and knowledge. I learned quite a bit. Look forward to what comes next.

mike what cubic inch was the motor you used the bulldogs on?
what rpm do you have to turn it?
i was wondering because of the 300 cc intake runner.

The 300cc Bulldogs would work on anything from a 400" on up. They would really shine on a race 440" or a pump gas 500 to 530" deal. 300cc is not that big at all. The Indy stuff starts at 310cc and goes up.

Hi Mike, What new developments have been made on the Bulldog Heads. I'd like to know what CC the intake runners are on the Buick heads that you said are flowing over 400 CFM. I went over to Bulldog and noticed the Buick block is almost here too. The Buick combustion chambers look real good and the spark plug seems to be in the ideal location. Very state of the art. I think all the Buick fans will be waiting antiously for the finished products to hit the market. The worst part of the Buick was the terrible oiling system, has that problem been changed?I'd like to hear about the Cadillac stuff as it's one of the lightest motors built by G.M. and there are still a lot of used cores in the junkyards. There should be a lot of demand if they ever catch on. They can be made fairly large with their 5" bore centers.

I can't recall whet size the Buick ports were exaclty. I think it was in the 310 to 320 CC range, but I'm not sure without my notes. The block has priority main oiling now. It's a real beefy piece and looks good. The Caddy stuff is awesome. I have a Bulldog topend and a 500" block and crank to start with. When I get time I'm gonna do it up and have some fun.

Hi Mike, I talked to a guy the other day who is trying to build a competitive Cadillac engine. He said he had an aluminum Bulldog head flowing real good on both the intake and exhaust sides. The Cadillac engine has 5" bore centers and a 10.8" Deck and weighes about 600 lbs. I would like to know what each Bulldog head flows after a little work, if you get the time please give us some information, i'm sure everybody is interested. The Buick head's combustion chamber is beautiful. Does the new Buick block still draw oil from the middle of the pan to the front of the block before pumping it back out? I have always thought this to be the biggest drawback to using a Buick as this location is the most likely to uncover the pickup during acceleration.

We made some big strides last night on the Olds BD exhaust port with seat cuts and valve angles. Very promising. The intake seats and valves are next.

I just finished a set of BD Olds big port stuff that I do. They flow 390. Yes I said 390. That's the best set of Olds heads in the world. We are going to do a 500" deal pretty soon with a set of these. I'll let you know what kind of power it makes. We are expecting 900+ with a single four carb. It will be in Hot Rod mag eventually.
