I have new ported y303 heads,a cobra intake,1.7 RR's and various other related intake,exhaust and fuel system upgrades ready to install at the same time in the next week or so on my 89 vert.It has been suggested that I should also change out the stock cam while I am at it.I want to retain a good smooth idle but the extra power would be nice.I don't drag race it,it is strictly a street car..Would a cam upgrade give me much more power with my setup?Any particular cam recommendations? Thanks.
