This thing is spectacular. Very nicely CnC'd and fits both sides very well. Word of caution though. I am using a stock 67 mustang motorcraft spacer in order to give me a PCV port on my 2100. There will be a HUGE vacuum leak, as the riser extends past the adaptor plate. I ended up tig welding a small aluminum plate on the stock riser then remilling the surface flat. Again, not an issue with the 2-4 barrel adaptor, only an issue if you are running a carb spacer between the adaptor and the 2 barrel carb. In addition, i also ended up polishing the CnC path marks on the adaptor and polishing it to match the rest of the piece. Obviously i now own this, and Speedway is not responsible for it. I figured it will flow just a bit better without all of the milling marks. Overall an excellent product, extremely well made. Much better than any other i saw photos of. Often the other spacers i saw has a hex milled in. I assume to keep the bolts from turning. But just didn't like that design. 10/10 Would buy again. 1945 GPW Jeep. 4.3l chevy v6. Motorcraft 2100.
