4" stroke . Was building a naturally aspirated but now thinking just building an engine to run factory rpm plus 20%worried head is ported out to much to make power at low end. Head is. 1100 massey and manifolds . Also running stock rods unless I need different. Any idea what hp and cubic inch it takes to run in a class much like div 4? Not planning on running d4 with that head it's just comparable to classes round here

500 ci is in the range needed to pull much speed,175 plus hp to maintain ground speed and have engine live on a power track,again a close ratio tranny helps bunches.You will need a billet cam shaft if planning on high rpms.(over 3k)
