Re: Interest in a current best science cam profile for the V8?

To get an adjustable valve train you may want to look at a modern shaft mounted rocker kit, possibly a small block Mopar or FE ford. If the detentions look close one may be able to trim this adjust that to make it work. You would have catalog replacement parts, slightly less friction in the engine so more power, and possibly more rocker arm ratio translating into more valve lift, plus the adjustability you are looking for.

I would think that a profile for a Pontiac or Buick would wok well with a Packard the breathing limitations and RPM limits of the design match well.

The casting would just be a swap of the top of the mold. A damaged head in hand would be good to go off of that way everything can be lined up exactly as needed. The foundry is OK doing a "restoration" head and it seems that a market exists. The Factory heads were raw cast and painted. A finer casting would be achievable, the porosity issues with early aluminum casting are all but gone with 60+ years of casting advancement. Like I said the heads as ordered from the foundry will be cast finish (though machined to where you can install it) But I would be open to polishing the heads as requested at my shop in Florida.

8.7:1 would definitely be the upper limit of of compression in a flathead. and I would venture a guess that high test gas would need to be used. if anyone has pictures of the factory aluminum head that they could send me, something with the details of the casting marks etc I will forward them to the guy making the patterns and see what he can do. The heads will likely be sent out in a cast finish as polishing is a long tedious process and would raise the cost quite a bit but I will double check and get back to you.

He can do a separate head without fins for people looking for an original equipment look. Price should be the same (1200-1500) I would need to know if a faithful reproduction was wanted or just a head that was not finned.

Tri-power would be cool and dual quad would be nice as the original dual quad manifolds are super hard to come by. anyone want 6X2 or 8X2? lol

HH56, the aluminum will be slightly thicker especially in the deck surface to help it hold its shape and seal. it may be a bit taller to hold more water but unless you have a stock one sitting right next to it, it would likely be tough to tell. The fins would be cast in and similar to an Edmunds piece. I can ask if he could optionally mill the fins off but it would likely be an up-charge. The rounded look can be achieved with a CNC operation but the head would need to be either sand blasted or polished to take away the machines finish.

Jack, what would you be looking for in a V8 intake?

That would be really cool, I would love to see more parts available for these engines stock replacement or performance. Injection molding plastics is very difficult from what I understand. Maybe 3D printing would be an option?

Yes the original aluminum heads are pretty beat these days and if you can find on in "usable" condition the aluminum is likely annealed and it would be difficult to make the head seal.

These will be a small market honestly not many people want an aluminum performance head for the Packard L8 but they will be cast in the US (Georgia specifically) and then CNC machined to completion. I am putting out the word for the guy who will be tackling the project and he knows that it will be a limited production/ selling item but he doesn't have all his eggs in one basket, he also makes other parts for forgotten engines (Pontiac straight 8 V12 Lincoln etc.).

This will not be a stock replacement part but a performance/ dress up part, it will be finned and the final compression ratio should be around 8:1, which is pretty ideal for a flathead.

Orders are not being taken right now as we are in the initial R&D stage but if anyone is seriously interested PM me and I can keep you updated on the progress.
