Intake manifolds

FL1970442 · September 5th, 2007, 09:43 PM

Hello, I have an original 70 442 convertible with it's original 455.
I sold it a number of years ago, and recently bought it back.
The guy stuck a mondello high rise intake, & a holley 850 carb on it.
It has a 3200 stall, and a 110 degree comp roller race cam.
Question, I'd like to put the original intake back on. Other than some
h.p. loss, will I have other problems?

If you go back to the original intake then you should put a stock torque converter and carb into it as well. I wouldn't want a 3200 stall in my car if everything else was stock. You might want to ask him if he changed the cam as well.

Seems you may have low vacuum at idle for the power brakes with that set up. I agree with Olds64, the stock converter would better suit a stock intake. Personally, I would go with Crane cam and a lobe centerline around 114. If you decide to go back to the stock intake and are willing to unload the Mondello top half, then send a PM. I would be interested. Other then that, it still can be street driven, it just depends on your preference. Good luck!
