Id like to add some visual pizzaz under the hood and boost my acceleration a little bit (Im getting a lot of dirty looks in traffic). I had some thoughts about some hop up mods for the original 170 (one of which was to remove it, put it in storage, and find a 185 from a 55 Champion, but I digress...). I know Offenhauser makes a 2x1 intake for this engine, but for low-speed drivability Id rather have 3x1 with a progressive linkage. Im thinking of keeping the stock Carter WE as the primary carb and adding Carter WO carburetors off a Willys Go-Devil as the secondaries. Id like to find a mild camshaft that favors the lower RPM range and has more duration on the exhaust side. Recommendations are welcome. Id like to either split the manifold or fabricate a simple dual-outlet header. This is more for sound than any likely improvement. Im thinking of running dual Porter steel packs through a stock-sized pipe if anybody has any feedback on that choice. Rather than scrounge up an aftermarket aluminum head, Id like to keep the cast iron head and fit some kind of high-compression piston. My understanding is that the chamber design on the Studebaker head is good, but that the bottoms are too thin for aggressive milling for a compression boost. Thus pistons seem to be the answer for a bit more squeeze.
