Re: ls6 cam
I think a #143 camshaft would be a nice improvement to a 427-390HP engine. I've driven stock 427-390's and they run good to begin with but I've always considered hydraulic lifters as a poor man's rev limiter. If you would happen to change cams, fresh new valve springs would be well worth the small investment.
