I don't believe there was ever a 305 in a Corvette , might be wrong but personally have never heard of one . I'm not familiar with the " Deception" emblems and can't offer any help there . You could do a Google search for " Deception Emblems " ( decepticon ? ) and see what hits you get ? There are many brake and suspension upgrades available for this car. There shouldn't be a problem finding those . Again do a Google search for those items. The dress up goodies for the engine also are plentiful and can be found many places ( ie - Summit , Jegs , etc. ) . Go to either web site (
www.summitracing.com or
www.jegs.com ) and order to your hearts content and your wallets ability . One place that offers various components for the early MC is Honest Charley's Speed shop (
www.honestcharley.com) .Pull up their web site and see what they offer that you might want to order . Hope this helps and good luck !
