Anybody ever Turbo Charged a Nailhead?

It's actually a Northwest Speed Co. intake. I don't think they're made any more. Fesler is right, it's hard to find performance parts for these parts and when you do, they are not cheap. Ours has the adjustable roller rocker conversion, gear reduction mini starter, and a custom Poston cam but other than that, the short block is pretty much stock. The heads have mild port work and SS valves. MSD makes a nice distributor for them also. They can be built to make some power, a lot of drag racers ran nailheads back in the day. but I think that was because the didn't have anything better to use

==========================================
What kind of Power are you making with your 425, and what are the parts and numbers you use to make that amount of power?

It's Ironic to me that Edelbrock will make Aluminum heads for the 409 that was only in production for 3 years and stopped production in 1965. While the Nailhead Engine was in production for 13 years and there were literally millions of these engines made, and production didn't cease until 1966.

From my understanding there were only 50,000 or so 409's made.

465 pounds of Torque at 2800 rpm's will really get most cars going pretty quick, and that's stock.

Oh well. Thanks for everyone who answered anyone else is surely welcome to answer if they have any ideas.

I really would like to make this work, even 450-500 hp and 550 ft. pounds of Torque would be a great level to get this engine to.

Thanks,
