This is the first 351 Cleveland, that I have seen make over 1000 hp, NA. The engine is from ACM Engines, And Dyno. The engine was built by Adam Cope, he messaged me and told me it was built in line with super stock DMS/A rules , in Australia. Cleveland's are 7.25 lbs per cube. I don't have a lot of info, but I can tell you it is, 440 cubic inches, and based on the Arrow 351 Cleveland block. The heads are Scott Cook race heads ported by Tony Oconnor. Also a big thanks from Adam to Kim Baker
