low 11's u'll need closer to 400kw and mickey t's
well rips over in nz have just built a 26/30 for their 240z drag car, are using std crank, std girdle, std block, argo rods, cp pistons and are revving it to 8500rpm. all their other built engines (similar spec) have been revving anywhere upto 8000rpm for years, not 1 failure.
mine'll be limited to around 8000rpm with the nitrous, but it could do 8500 easily with the grout filled block and billet girdle.
