Thanks for all the info guys!!! The bottom end is pretty stout, it has a steel crank, good rods... etc. I am just so used to running the drag racing stuff, this is a totally different kind of combo than I am used to running. My last motor in my drag car was a 540 inch BBC. Merlin Block, Grumpy Jenkins heads, Callies crank, 15:1 compression, on alcohol... Not really a street motor.. lol
