The fastest thing in 14.5 ci factory block and head small block class is a BSP clone with about $1750 worth of trick stuff in it. In 2016 Flash06 had a clone with broke crank, effed rod, bent cam and cracked block, I had a seasoned BSP stock bore block which I punched out to 2.814", Mitch got new stroker crank and rod, I had a new welded dyno cam, so finished honed the block to fit the old piston, clearanced the block for the rod, cut off he compression release on the cam, freshened the valves, put her together the way I do, the ARC billet side cover dowel holes never seem to fit the BSP blocks, so I leave em out and do a little trick with a quick trip to Fastenal, we put on my 15 Exceed flatkart went to Dawgwood ran the first 16 Ga. UAS series race, got a 4th, had 3rd he whole race, but a late caution bunched up the field and Mitch got pushed up going into 3 on the white flag lap and we lost the spot by 1/2 nose coming to the checkers, then we went to the next Ga. UAS race at Shiloh, no it ain't enough to beat the Bama 250 smokers or the 500cc Jawas or the CR450Fs, but it's enough to make the show and get points, she did win the Open Mod. 375 at Shiloh starting from the rear with Micheal Register on wheel weighing in 405. LOL little dawg i'll hunt.
