I have a CX-8 manifold on my10 over 350. Called Crane and got a flat tappet cam designed for it, added 2 600 vac secondary Holleys and jetted it down to .60's. For the street it works okay. I still have a very slight bog when I jog it fully open, but it catches up very quickly. I like it because I traded it for a manifold back in 1971 and keptit all these years. It fills out the engine compartment very well for a tiny DJ3A Dispatcher Jeep, and is very reliable with the electric chokes (I use only one) but I'd like to learn more about balancing the two carbs for better performance. ANYONE?
