More Power for a pair of 377MX MPI'S
I am looking for some ideas for reliable HP for my 377'S
I was thinking of a set of comp cams roller rockers(mag 1.52 ratio)
I do not want to do any major work(heads/ exhaust)
Maybe a set of cams? fuel injection/injector work
Any ideas? (not bigger motors either)
Thanks

Re: More Power for a pair of 377MX MPI'S
There has not been a lot of talk about modifying these engines.
Better flowing exhaust would be one place to start.
I would talk to one of the fuel injection gurus before thinking about a cam change. Mark at Precision EFI or Tyler Crockett are two of the best from what I've heard.
There is always the supercharging option if you want to spend the $$.

Re: More Power for a pair of 377MX MPI'S
What would you suggest fora exhaust systems?
What type of Torque and hp #'s would be achieved by changeing the exhaust?
Does the riser height mean anything for the hp & torque #'s or is it there to get it out the existing holes in the transom?
thanks in advance for the info

Exhaust improvement is the way to go with the SBC. I put Stainless Marine on my 350 along with a head change, carb & intake change, ignition change and 1.6 roller rockers. I need a cam change but I'm in no hurry to pull the engine.
