300 RW HP w/ a NA stroker? Um... I got 169 w/ a Golen Stroker on a mustang dyno (vs 136 for the stock 4.0-same dyno). Golen sent me a video of the motor making 280+ on their superflo engine dyno. It runs well and is a definite improvement but doesn't knock my socks off...The reason we are doing a stroker on this one is to avoid the cost of the V8 swap. That and to try and sneak it past the smog stations. I'm being promised over 300hp and closer to 325 with a high level of reliability. We'll know shortly if that is true.
