Lenny, did you machine out the stock throttle body or did you change it to an aftermarket one. I was going to match ports as soon as I can find gaskets I think there are some on ebay. I have seen on here that some have flipped their intakes, I can't do that on mine pattern is wrong. I was going to redesign the intake to just an aluminum box that bolts to the steel manifold. I think that buy shortening the runners it will increase the low end power, the longer runners are good for high rpm running but too much volumn for low end,these engines are to small for the setup as is. What do you think?
