Thread: Anyone used "Peanut Ports" on your BBC?

Pat, you left nothing out. I personally always look for your replies. Thanks for hangin in there.

Okay folks, I have been contemplating what 30-A Rider said and feel like I owe you all an apology. I re-read my posts and, it is possible that I may have come off sarchastically even though I tried very hard to write in such a way that one would not get that impression. I certainly did not mean it in a "mean" way. Also possible that I interpreted Erik's reply-post in the same fashion and shot off a response without thinking. Erik, my tone in real life is not near as severe as how it may have come across in words on a screen. Take that for what it's worth.

So, sorry for all that mess. I am not a mean guy. Stubborn maybe, but not mean.

For those interested, I will let you know how it turns out with the small ovals. I found a group of folks running them on the street with some success (like Blackroc) and little on the investment side so I may try it for a while and save some $$. A running BBC is better than no BBC at all.


There, now I feel better.

I should add the sbc I had in my car prior to this 454 ran 11.8xx so I definately noticed a drastic change. Althought the 454 with the peanut ports isn't too bad till it runs out of air.

This was what happened to the last sbc and then I decided to try a bbc for a change.

Agreed. Pat's reply said pretty much everything I beleive.

Just wanted to add my $.02. I run a 454 with 236 peanut ports in my 26' boat. I too run out of air around 4500 rpms, and want to go to around 5500 rpms.

I plan on switching to some 049 or 781 heads soon and running her until she needs a rebuild then I will make her a 496 with forged internals and then may really rev her. Oh, if I didn't run in salt water with raw water cooling (cooling water comes from body of water you are in) system, I would change to aluminum heads to save weight. I thought about putting a closed loop cooling system in, but will just stay with cast iron heads for simplicity.

Unfortunately, I don't want to loose low end grunt, which is why I want to keep the same pitch prop but just rev higher.
