I have a 408 stroker and I want to put a comp cams XE275HL cam in. The specs on the cam are 275/287 duration (231/237 @.050) and .525 lift on both. The suggested springs are Comp 995’s. I have Edelbrock aluminum heads and have changed the springs to PAC 901’s. I’d rather not change springs, so I have included a comparison sheet. Will I be OK?
