Just wanted to follow up on this thread. I waffled back and forth on the Canon manifold vs hogging the stock manifold for a while. There were pros and cons of each. I ultimately went with the Canon. Andrew Adams was kind enough to answer some questions for me and politely said that if you are going with the Canon that i should port match it to the head for good measure. So I did. And he was right.
I took the car out for the first time about a week ago. The carb isn't totally dialed in yet. I'm still fussing with the idle and the mixture a bit and have yet to set the electric choke. But wow, when I hit the gas that thing took off! Way better than my 32/36. It pulled hard all the way to the redline where my 32/36 had a stumble around 4500 RPM. This thing just ripped.
Two things sold me on the Canon. It sits a bit lower than the stock manifold; which gives me more clearance over the top of the ITG filter I use. It also doesn't have the vacuum ports that need to be plugged like the stock manifold. i was always replacing those things. Oh, and it was new and shiny.
I have an MSD box that I'll be installing in a couple of months and will change the plugs and reset the timing after. I'm just really happy with the results so far. Feels like a totally different car.
