    If there is any way to second a moton that has already been seconed , contact Bill Cathcart, I drove my 57 6 cly Silver Hawk 30,000 miles and used all the gas that was at the pumps Ethanel 10% with no problem , but the performance difference with the Stage 4 that Bill made up for me , is fantastic, no simalarity at all, Finned alumminum head that says Studebaker built right in looks great, Dual carbs on an Ofenhouser Intake manifold,He makes up the special dual exhaust manifold 3 to each, unbelivable sound, not a six and not an V/8 sound, at the same time electronic ignition, ported and polished, as Bill said 185 cu. in. put out 101 H.P. and with all the extras it adds 50 more. I now have put on almost 9,000 miles since this spring, and its great, Contact Cathcart Stutebaker and talk to Bill.

      57studesilverhawk- where in Canada are you located? I have been looking at the Cathcart site as well. How did you ship your engine back and forth. Any issues with the boarder?

        I live in Saskatchewan, just north of Plentywood MT. I crossed on a good day in the dead of winter, no problem going down , I picked the motor up in Fargo ND. had good weather all the way down but saw black clouds behind me, and asked at the dispatch counter about road coditions, her repley was the highway you just came in on was closed, the next hwy back had storm warnings, my next question was what about straight north into Manitoba? thats still good, well since I had all that extra weight in the Ford Ranger all was good, and I left very fast.No problem at the boarder gave them my receipt, paid the tax for the federal government and since I wasent in Sask I never had to pay our tax,however the storm meet me at 5 AM that morning and I plowed a foot of snow for the next 300 miles, thank goodness for all that extra weight.It turned into a 20 hr. turnaround maybe not the best thing to do but hay it was for a great cause I now had a Cathcart engine, and I havent looked back, as I said before I drive my Stude Hawk almost 9,000 miles this summer, and love every minute of it,it soon will be down for the winter.Generaly if you have your documentation with you and present it at a busy boarder crossing , no problem however if you go to a small unused crossing, they find something to do when a unsupecting customer comes and you can spend a few hours answering all sorts of questions.

          Thanks Evan. I don't want to steel this thread but how long did Cathcart have your engine for? Chris

            He supplied my core as living in Sask., the shipping of a core was more than what he could pick one up out their. From start to delivery was about one month.I've tried adding the engine pictures in the post but as yet cant do that,hum

              The dual carb setup might work okay but it seems to be overkill as far as price and performance goes. I had a two barrel on my first car a 170 OHV; a cheap improvement. I used an adapter to the original intake and it worked great. I could see the aluminum head to raise compression, and a cam, but a lot of the other stuff is just for decoration. It just seems like it belongs in a Model A or something of that vintage. Is the cost of the aluminum head really worth the bucks or would it be better to deck the block for compression?

                "she's ported and relieved, stroked and bored..........."

                flat head "porting" extends to include "relieving" the block in the areas between the valves and cylinder bore (watch out for the piston rings' travel) , as well as shaping the cylinder head.

                There was a time when the highest performance flat heads ( Harley KR? ) were carefully sculptured in those areas.

                Nowadays some claim it can all be done with the cylinder head. If the late, great Barney Navarro chose that path, I am inclined to listen.

                Maybe not such a big deal if you shift at 2800 rpm or so
