Fifth gear snap ring came off after a spirited test drive of the 383. I popped it back in place and tack welded it so it doesn't pop back off again. 500 miles later and no problems.I finally got the 383 dynoed. It made 382rwhp and 425rwtq. Not bad considering I used very little timing and NO NITROUS. It should make over 400rwhp with more timing. Here are some pics of the car on the dyno at Proven Power in Tampa.
