I AM CONSIDERING DOING SOME KIND OF ENGINE WORK ON MY 65 AND WAS WONDERING IF ANYONE HAS USED ANY POWER ADDERS LIKE TURBO OR BLOWERS?IF SO COULD YOU LET ME KNOW WHAT YOU PUT IN AND HOW IT WORKS FOR YOU?

I haven't done any of this yet but if you have time to visit this site http://www.inliners.org/ check out their bulliten board. They have a lot of info about this kind of stuff.

This company has a turbo exhaust manifold for the 250ci and distributors all over North America.
Inliners requires you to pay to be a member, but do a search for turbo 250ci here and you should find a link directly to the Inliners Blower motor page.

I don't think you have to be a member to access Inliner's bulletin board. Give it a try.

Of course we welcome new members. There is a lot of knowledge to be shared by the group.

Contact Hank at inliners (Mean-buzzin-half-dozen). I think he forgot more about hopping up the 194/230/250/292 than most people ever knew.

my 67 has a 250 six cylinder and I would not mind to do maybe a cam swap or work on the head a little for some extra power myself !!

A mechanical blower or turbo can certainly produce a lot of power, but the biggest gain for the money is mild boost with a nearly stock engine, otherwise it's another money pit.
Read my article: http://victorylibrary.com/mopar/blower.htm
Conventional speed equipment (big cam, ported head, 4 bbl., header) is a nice project/hobby, but not cost-effective in terms of power per dollar, or maximum power. You still have a small engine when you're done.

For the cost of adding any kind of boost, either turbo or mechanical supercharging, you can do a lot of more conventional go-fast modifications. You'll need to do an engine rebuild in the process, however. The 250 has dish-top pistons that serve to lower the compression ratio to emission-controlled levels. By substituting flat-topped 307 V-8 pistons, which are a direct replacement, you'll get a compression boost. I've built 250's with pretty radical cylinder head milling, .050" in one instance, without piston-to-valve interference problems, but I was using a stock cam in that one. If you can get away with a fairly radical grind cam AND high compression, that's the best of all possible worlds, because the compression bump compensates for the reduced cylinder volume created by the longer duration cam on the compression stroke. In most cases, the effective cylinder pressure isn't much more than stock, even with high-compression modifications. Using a radical cam WITHOUT increasing compression is a huge mistake! Improve the intake and exhaust with appropriate manifolds, and add a high-performance ignition system. You'll spend about as much as adding a turbo or a blower, but the power increase will be a lot more noticeable.
