After about 6 months of searching I found a decent deal on a boat that needs slight tlc my buddy is picking it up right now. I work out of state so I sent him to get it. Its a 1970 rogers cyclone 455 tunnle ram dual 660s basstes and a berkly jet. Don't know much more yet hope to have it in the river on memorial. So questions my are the seller said it was a half stringer but I thought all rogers were full? Is this a early version? Is it a bad year? Read great things about rogers so I was excited to get one. What should I look for problem wise? Are there any areas prone to stress cracks? How can I tell if the motor is one of the early "better" 455s or if a junkyard car pos? And what else should I be looking for I'm very new school me please.

The cyclones were 3/4 stringer. As long as it is the 17'6" hull. The 16'6" hulls are 1/4 stringer.
As for the 455 Ka heads were marine heads. I don't remember the code for the block.

First off welcome to the site. I don't know much about the Rogers hull but I know about the 455 olds motors. One thing you should ask the po is if he opened up the return flow for the oil returning back to the pan. Olds are known for burning up bearings from lack of oil returning to the pan. Another thing is if the heads are Ka heads then there the marine heads which is what you want. If the passage ways for the oil have not be opened up I wouldn't stick my foot in it for more then 5 seconds and keep an eye on that oil gauge. Otherwise good luck and welcome to the addiction

Po doesn't know any info on the motor. Boat was sold in 1970 with a 390hp 455 according to my research so I'm hopeing it hasn't been swaped out for a junk yard car motor.

Welcome to the site bud I'm sure someone here will school you on a lot of things as they did for me as he said welcome to the addiction of empty pockets an a lot of fun lol

Have no idea how to post pics from my phone at work. Give me a cell numberand I'll text them. Buddy is headed home with the boat right now. Got it for 1800 paint is rough interior and gauges are new. Needs a fwd reverse cable. The gas pedal mounted and the tanks secured but she fired right up and sounded good.

Pump is a 12 jb it doesn't have a jetavator or a place diveter or anything. Motor appears to be a marine casting full malory ignition setup dual 660s no clue the internals. Was told they were 390hp from the factory in 1970. Hope she will run mid 60s if I can squeeze 67 or 68 out of her ill be the fastest in my group.

Is this the same boat that was on clist in Bellflower?

I'm pretty sure a 12JB is a split bowl, I think it's a JC but I could be wrong

Yeah its the bellflower one. Sent a buddy to look at it. He said it was a lil rough and needed a lil tlc but it sounded healthy and offered 1800. Figured I wasn't gonna find another rogers that cheap. With out just calling me stupid can you explain why it was a mistake to buy it? Only other boats I found under 3500 were not even close to what I wanted.
I'm new to boats so if you know something I don't about it let me know. But go easy on me I'm super excited and really dontwant my bubble bursted

It is a split bowl guess there pretty much same pump as a jg

Haha... That's his signature that attaches to every post he makes, he wasn't calling you stupid... But that's some funny sh!t right there!! From the pic of the pump it doesn't look like a split bowl but it could just be an optical illusion

Cap what? Are you refering to my lack of gramar skills? Because I'm running heavy equip while I read and post so its kinda hard to proof read.

No, reading thru previous posts it's something done to a boat but I'm not really sure what it is... So if someone can explain what capping is and why he (or myself) would need to do it that would be great

I'm no expert by anymeans but if you cap it you are eliminating the rub rail and making it as though it is one solid hull this is what we are gonna do to the kachina it looks super clean

Says 12jb on the plate but I'm deffinitly the least educated person here so if you say its ajc I believe you.

My main plan for the boat is to do the bare minimum to make it run and hopefully drive the hell out of it all summer.

This site and the great family of people on it will be your new best friend!! Reading previous posts will help you learn a lot and still not know anything haha From what I understand (reading as many old posts as I can) the bowls are interchangeable so it might have been a JB originally but at some point in the last 44 years it could have been swapped to a JC bowl for whatever reason

Also, there are a lot more mods that a 455 needs besides the oil returns. Main restrictors, restricted push rods, high capacity pan and the list goes on... I just got mine back together. Rushineliminator Phil knows these motors big time...

If it is the original marine block and heads than all the oiling mods should have been done at the factory right?
-
Where and what are my casting numbers to verify its a marine motor?
-
I was on my way to buy that one last week n he called back said it was sold.

I bought it this morning. Swindled the guy down to 1800. Sorry man.
-
Heads have a e casted in them. So I'm guessing this is a pos junkyard car motor?
-
haha general lee wasnt saying it was a stupid move or that u shouldnt have done that, that's his signature. haha Multiple people have fell for that one. if you notice, every one of his posts have that at the bottom. but welcome to the site brotha! my names Ryan.

There is a pad on the block, right below that 1" letter casting behind the alternator that will have some stamped numbers on it.
If you see two rows of numbers, upper row starting with an "L", this signifies an original or marine issued block.
If there is one row of small stamped numbers, this signifies it was a passenger car block.
I would have lake tested it before purchase...engine problems become evident under load... Trailer running means very little since there is absolutely no load.

I mean, fill the joint between the top and bottom halves of the hull, where the rub rail usually covers. Those barrel back hulls look so sick when capped and smoothed. One of my favorite hull styles.
Cheers,
Joe
P.S. Belated welcome

Casting numbers start with L. that's good right?
