Knowing he wouldn't need enormous runners for the amount of cubes, Dale kept the volume down. He says: "The intake port is way smaller than the original. ,think the factory was 152 cc and now it's down to 145 and it's much higher. It's got a small cross section of 1.91square inches]." Final flow numbers ended up around 195 cfm on the intake and 170 on the exhaust. Though not huge peak flow numbers. he claims they were almost at those numbers by.200-inch lift. Just perfect for limited camshaft and rpm range applications.
435 HP and 430 TQ from 316 cubes and from only 195 CFM.
