"I know it'll make much more than 700 at peak and have strong average numbers to score well in the Challenge. The cam is pretty aggressive, and with a slightly milder cam this would be a great street engine. The valvesprings are not huge, and the test rpm range is low. I wanted to build and test with a mule shortblock the way Joe Sherman did last year, and then bring my fresh stuff to the Challenge, but I found a crack in my spare block and I can't test with it now. So, this is it; this is my only engine. I hope it does well, and I hope the Buick fans out there see how much potential there is in a stock block/stock crank combination like this. It takes more time and effort than a Chevy would, and probably more money, too." We at PHR know it's cool to have something different, and if it happens to be a near-800 horse Buick pump gas engine, we're on board! Thanks Bruce, and we wish you the best of luck in the Engine Masters Challenge!
