Hi all

Just a quick question about porting. I am going to purchase a 13b block that has fullcut bridgy or monster bridge.

I know there is half bridge and full bridge but what is a monster bridge? is it the same as a fullbridge?

cheers

 

"Monster" could mean anything. Could just mean a big bridge, but could be a massive port that cuts into the water jacket. You'll need to clarify with the seller.

You should be able to get a good view of the port through the intake runner if you have a bright light and a small mirror. If it cuts into the water jacked (called a "j port" on this side of the pond) then stay away. Such ports were only used in racing to get around anti peripheral port rules and have a VERY short life span.

 

Depending on what you are trying to build you can get away with a "monster bridge" but as Aaron Cake said they life spam will drop drastically.

 

Cheers aaron and chris, yeah we also call it j porting here if it cuts into the water jacket.

I emailed the seller and he stated that the engine builder told him it was the biggest bridgeport before you need to cut in to the water jackets so that makes me at ease a lil bit as like you said aaron j ports dont last long and im not planing on racing so i do not want one

 

Just make sure your gonna be fine with the noise of a large bridge port cause it may go over the decibel limit and you might get a ticket. I know a friend that has a 20b pp and just idling is over the sound limit.

 

Also remember that going to a brideport means a lot more supporting mods. Standalone, big turbo, and all the trimmings.

And there's nothing worsethan driving a carbureted bridgeport.

 

whats so bad about driving a carby bridgy? out of curiosity

 

I'm just guessing but I think it would just be very hard to tune. In general, carbs are hard to tune, but then it would be even harder because now you have two intake ports. It would probably even increase the difficulty even more. Just a guess

Carburetors are responsible for the bad press that bridgeports get. Due to the pulsing ambiguous vacuum signal they can only be tuned very crudely, with no adjustments other than a general fuel curve. Couple that with very poor control over timing via the dizzy and you have a poorly running engine.
