Individual runner tunnel rams where popular in Pro Stock for a short while in the 1970s on BB Chevy, Fords and Hemi motors
This add is for SB Chevy, correct? Including two new carbs, linkage and new special cast aluminum IR manifold at the retail price is probably not a bad deal
I've converted more than one in line dual quad set ups on both 360 degree intakes and dual plane intake to one to one linkage to make then run better, way better on the early hemi motors and wedge motors with the dual quad single plane intakes
I've never ran or race a IR tunnel ram motor so no hands on experience in tuning them or driving them
