intake question
I have a question about sb intakes. Why is it that on some intakes the rear water jacket holes are blocked off? Would it not be better if they were open? I was concerned about the back cylinders. I have a 289 stock intake where the back holes dont cross over and a aftermarket name brand intake for 289/302 that the back holes do cross over. I have thought of drilling and tapping the blocked off holes and run a crossover tube. One othe intake i have that is closed off is an intake for a weiand blower and i have water flow problems with it.
THANK YOU
