Real happy with the performance of my new Faster Motors Briggs. I had to gear a little differently--I normally run around a 4.2 to 4.4, now I'm like 3.87 and hitting the rev limiter at the tail end of the longest straight. The only problem besides backfire on decel, was the oil spewing out of my fuel pump and making a mess of my new motor. I can probably figure out a way around both problems.
