I have 2 pair Imco PFP Manifolds & 30* risers installed last year on my 35' Cig 572 twin BB chevy's...........only 2 hours of running time since install............ This year we only ran engines on the hose since upholstery work delayed my summer.
The boat ran great last year after install.....The reason for new manifolds and risers?.... previous owner (in Florida) did not flush before storing boat away.....thus the old PFP manifolds were eaten up by the salt....on test run several holes blew
out and almost hydro-locked engines........I replaced the PFP Imco's & 30* risers that Flagship Marine (Punta Gorda, FL.) originally rigged with........Great engine builders, but terrible method for their long tern storage of boats.

524cuin BBC. The cam doesn’t come in until 3000rpm which makes it easy on the drive getting on plane. But when it does holy smokes. You can hear the difference, it lets out a roar like get out of my way.

bravo boat?
