Does anyone know what size the idle air hole is in a stock ls1 tb? Looking at buying one ported and polished pretty cheap put it looks like the hole my be drilled out im not sure. he measured the hole and said it was 5/32". I plan on running this on my stock trans am right now but in the process of doing full bolt on and head cam. i suppose if it is bigger i can just wait to install it until i get the cam in. lol but thats never been my style! new stuff just has to come out of the box and be played with!!!!!!!!!!
