Want to know if any of you guys do any serious roadracing with a 351W or 351W stroker. I am about to install my 383W stroker and plan on doing a lot of RR with it. However, I have been comming across a lot of things basically saying these motors are not very cut out for this type of duty. My set up is in sig. Just tell me how yours ( or anyone else you know) is holding up. What do you shift at? Whats your setup?
