Not Bad Vmax. Looks like the Animal Pro Gas engine with the World Formula red 7100 coil. Might just work, good thinking! Personally I like the idea of what you say except use a 8000 RPM coil. This would fit more race series. The dirt / pavement oval needs 7500 and the sprint racing needs 8000 RPM for good racing, so the 8000 rpm is best.
Our thinking is starting to line up a little, like maybe 75%. It would come down to Briggs and Stratton Motorsport group decisions. They have to always be thinking on what options will gain the most engine sale volumes per engine platform change. They need sales volumes 10,000 +, not below 1000 engine sales.
Is our $795.00 fall sale price for a race prepped and dyno tuned Animal Pro Gas still too high for you? You can build it yourself cheaper!
