That is a big cam, .438 intake lift. Where it's really big is in duration 280 degrees at .050 lift. You will have to turn that cam hard to get everything out of it. Dyno recommends 9600 for target max rpm. It was designed for 16 CI JR dragsters and all you have is a 13 CI engine, it's not gonna have a lot of bottom end with that kind of duration on a small motor which will make it even more important for you to turn it hard. Any stroker will help with power because of the added engine size but the biggest ones are harder to install because of rod hitting the block , cam to rod clearance, they need more work done to fit them in without parts crashing into each other. Your 4.500 rod won't work with any stroker crank. Jon
