I have a bone stock 84' CFI pullout I am going to install in my 86'. I will be removing the CFI and installing edelbrock airgap and holley 3310 i figure. My questions are what is the compression of 84' engines. Are the heads junk? What about stock camshaft? I figure to be pulling all tin and replacing gaskets so i might entertain a head and cam swap. I do not want to go crazy would like the stock t5 to live. 86' has great power brakes and a/c and will continue to do so.
