I'm restoring a 390 IP engine in a 69 Mustang GT fasback. What would you recommend to wake up the engine? I'd like to keep it generally a stock rebuild, bore it 30 over, keep the same C8AE-H heads and Autolite 600cfm carb. Can the C8AE-h heads be worked to CJ specs? Are there any header applications that work and can fit in the tight engine bay of this Stang? As well, what would be the best way to reduce the 10.5:1 stock compression to accomodate fuel at the pumps?
What is the difference in my 3U crank in comparison to other 390/427 cast iron cranks that are available?
This thread, so far...
