i have a set of cast slp runners,has anyone on this site ever siamesed them?was going to buy the superram but i think shortening the runner length so that only the runners in the base are seperated would work just as well.if i remember correctly chevrolet was gonna do a 350 6 speed combo for the 92 model year using an l98 an a zf with special runners that were completely open.give me your thoughts!!!!!!!!!!!!!!

if you can siamese the SLPs do the base at the same time. but only do the base back about 5" from the opening.

this will help out your upper end and up your red line about 400-500 more.

and also port your plenum to match and cut all of your gaskets to match also.
