That's one thing you'll find out about me, I like to joke around a little every now and then.

As for the cam, is Ed willing to do more of those?

I really like your car I saved some of the youtube videos of it I'm looking to put a small roots blower on my straight 8 I'm not looking for any speed records just something different with a little more oomf than stock. I know Eric is getting a lot of my questions answered along with things I haven't thought of yet but I wanted to ask where did you get the aluminum head from?
Thank You

The easiest and cheapest way to get more "oomph" out of a Packard straight eight is to put a 4bbl intake and a 288AT head on it. Probably the cheapest and easiest way to go.

Brian: Thanks for the great photos and info. Your roadster (on youtube) inspired me to build one also though mine is for general back roads cruising and is not blown.

Anyway, I agree that a full relieve job is not necessary and will just drop compression. I have had good success smoothing out the edges of the little saucers that the valves sit in. As the Packard valves are tilted toward the cylinder the mixture doesn't have to travel too far!

Here are some photos of a cutaway unmodified 288 (=327=356) as the architecture was all the same. You can see how the mixture would flow up out of the port and be directed by the hollow in the head. I also like to cut a big chamfer on the top edge of the intake valves to make a wee bit more space for the mixture to flow over the top and around from the back side. A little finessing goes a long way.

Am looking forward to further installments.

Thats a great cut away picture. Really put things into perspective.

I have over 500 pictures I took while building this engine. Took about 6 months to complete and a lot of cash!!! I will post more as time allows. Been working on a Caddilac intake for a buddy.

G'day StraightEights&Aces,

First up, see it's your first post so to PackardInfo. Second, for including your 2 x '52 250 Mayfair Sports Coupes in the Owner Registry.

And third, this quote is a reply from Brian to a question on one of his YouTube videos, sorry I can't remember which one.
"the head is a hand made piece machined on a manual mill and it uses two pieces. check the newest video for a look at it, It not the best shot but its there."

The piston is hanging by ring tension. The cutaway is for discussions just like this one and as a sales tool for customers who are curious about their engines. Oh, and fun. Which I think is what ALL of this is about. I also have a cutaway Ultramatic which I'll post elsewhere to not disrupt this thread.

Excellent build. i have been reading about the car on the Hamb also. I'm in the process of building a 51 288 block with the AT head. You have given me a lot of great ideas!
