hey geezer would you be able to desktop dyno my combo on my 'first 496 build a running success' post please? its not a very extreme build but i wouldnt mind a rough idea where im at for power and there arent any reputable chassis dyno operators in my area. all the specs you need should be there, need any more just ask. cheers man
