I want to love my Gutsram but I think it might be killing my bottom end. This is on a OEM block 474 w/Hi-Ports that flow 380@800, camshaft is solid roller w/760 lift [email protected], 108LSA. I am running 2 660 center squirters . So after 20+ runs on this new Gutsram equipped combo with ETs averaging probably around 10.25 @ 134.xx w/1.51 60ft, I decided to put a Victor with an 1150 on it to see if the 60 ft picked up. The 60 ft picked up right away with a 1.45 60ft and it even gained over 2 mph. Its possible the 2 mph gain was from better air than any day I had raced previously with the Gutsram combo. And like you said, the Gutsram had lots of work in it getting the ports matched up.

I still plan on using the Gutsram but I have some ideas to make it better suited for my combo. I want to take some volume out of the runners. I saw somewhere on this forum that somebody mentioned port reduction plates someone made for a Gutsram. I cant find that thread or post but would surely be intersted to see what others have done to take volume out of the Gutsram for smaller (474 vs 535) cube engines
