opening up intake on metra65 to match 21mm carb

yeahhhhhh

i'm going to open up my intake on my metra65 to match my intake manifold&carb. i want more bang for my buck.

any tips or pics? i need some moral support before i dabble in the black arts. yeahhh people do it all the time, but i feel like taking a dremel or file to my kit is just asking for trouble.

also, should i attempt any mild porting? if so, keep those tips and pics cominggg.

If you are just opening up the outside of the case to match your intake, no worries, just go slow and stop when your done. Make a smooth transition. If you want to port the cylinder, I have no personal experience, but I'm guessing people would say widen your intake and exhaust as much as you can without compromising the ring pins.

thanks phil! that's what i did and it turned out really nice.

now i am just polishing up the exhaust port. rough intake and smooth exhaust, right?
