Man is this forum boring lately.


WE NEED FREAKIN' SUMMER!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Well I must say, I don't have much time to check this forum, my son is on it all the time and is responsible for me having joined this forum. I have a question about Camshafts. Likely, someone has already addressed this but I would like to ask anyway.... I intend to freshen up our 454's , they are 365 hp magnums. I have purchased 1 set of roller rockers and lifters. I am looking for another set, I have been watchful to Ebay, lookin for deals... Anyway, I will eventually obtain the 2nd set, and i was wondering if anyone could recommend an appropriate marine roller camshaft. Our boat is a 311, and I am not looking for anything too wild, but would like something with some snot. I am hoping ( likely a fantasy) that I can just re-ring and put new bearings in. I will tear it all down and have the block boiled and new cam bearings and frost plugs installed. Freshen the heads and all that... I am still curious about what the difference between the merc 365hp is vs. the 420hp. I read in another article that the 420's seem to have all the same "goodies", per se... I.E. forged crank and pistons.
Also, they have the rectangular port heads. So is it just the camshaft that makes the difference in horsepower? Any thoughts that anyone has would be most appreciated.
Thanks, Quikdecision.....

Hey ThirdBird, how boring is your life at the moment for you to seek excitment from an Internet Forum?

Life is what you make it so get out there and make it Buddy.

As he types commentary from his computer...LOL


I do agree that winter (up north!) is boring without boating. Boat payments in the winter are tough too. All of that money from November - March in payments but can only use the boat April - October. I think guys in Florida have the right idea. I keep telling myself that inexpensive winter weekends allow me to save up $$$ so that I won't feel so bad burning through $200+ of unleaded gas per weekend in the summer.

This thread needs a picture. One of our favorite past times is cruising the bay and taking pictures of lighthouses. This one was easy b/c it is right near the marina. We can't wait for the spring thaw!

This question would be MUCH better to address in the tech Q+A area. You will get a LOT of replys from some guys that really know their stuff.

At any rate best I know the lower ends are the same. The top ends are very different. 420's are all roller valve train. I also think that they are oval ports not square. Don't be worried about that however as your square ports should be able to make a few more ponies.

Good luck
Jon

Who is your son, just curious

Cause im 16...

My son's name is Dustin. He's 14 going on 44.. He's pretty darn sharp.. I'm a lucky dad.

You mean it's not summer????

Today's run up to MarVista. The bridge is one last 3 remaining "swing" bridges left operating in Florida.

Tee shirts, shorts, and lots of sunblock, oh yeah, lots of bikinis thrown in for good measure.

Not funny

Outlaw, your lucky!!!
