if you have the engine apart and are going to go with a hi-po engine you should port match everything. this will make fuel and air flow a lot better. it makes a difference. that is pretty eash to do by yourself if you are really careful and have a nice grinder. you should have someone else do it if you are not certain of your skill or do have the tools. better cam and a bigger carb will do you good once you have all that done. i have no idea about a stroker crank. i will be honest and tell you that i have no idea what stroking is. i am guessing that lifts the pistons more than usual. matthew bajda
