Starflite Rebuild

Thats insane Roger...Larry, Moe, and Curly weren't close by were they?

Reminds me of the story of the guy that built a boat in his basement...lol

That is pretty cool! I found a rare 1943 steel penny when restoring the Skier. There was a bunch of change under the gas tank and and when I was cleaning it up one of the pennies shined silver instead of copper so I looked into it. They were made during the war when copper was in high demand.

Pete, does the UK fall under ACBS guidelines or is it basically an American thing?

Eric,
The ACBS is international although most of the members are here in the states.

Don't worry Pete, all that is seen will be ACBS not so much the other   

Tim, did you catch that ?

Both are RH solid roller

Meaning they are not hydraulic....This is not only possible but probable...Twin engine go fast boats,ie Scarab, Cigarette...

Ive never heard of or seen a reverse rotation roller BBC cam of any type, hydraulic or solid. Interesting!

That firing order (12756348) is indeed for a reverse rotation BBC. The lift looks to be out of this world... .708 at the valves! Thats a race cam if Ive ever seen one. For reference, my warmed up 351w has .490 at the valves, and my warmed up 454 will have ~.560 at the valves. This is a whole 'nother animal. I doubt you'd be able to make use of this cam in one of our boats, as its just too wild... but maybe it can be reground to something a bit tamer?

Anyone know if theres any way to run hydraulic lifters with a solid cam? Maybe the ramp rate would be too agressive... what about if it were reground to something tamer? How do the metallurgy compare between the 2? I know the flat tappet vs. roller blanks wont allow you to mix and match, not sure how solid vs. hydraulic compare.

As far as using a flat tappett on a hydraulic or vice versa is a sure way to wipe out a cam. Different ramp profiles are used on all three types of cam/lifter systems. Bottom line is do not mix components and expect a "happy cam"..........Boat dr

Yup, learning something new every day.

If you re-read above, you'll note my question was not whether you can mix and match flat tappet and roller cam components (I know thats a no-no due to the different hardnesses of the metals), but rather whether you can mix solid and hydraulic components. I realize ramp rates are usually different... but is there anything else precluding you from mixing the 2?

IE, could Roger regrind that solid roller into something a little tamer and then use hydraulic roller lifters with it? My guess would be yes- but thats just a guess. Im assuming all roller blanks (be it solid or hydraulic) are of the harder billet steel variety... but again, thats just an assumption.

I called all the big outfits (Comp, Crane, Lunati) and a bunch of small ones that came highly recommended for BBC work- including at least one that specialized in high performance marine engines. None had any record that a reverse rotation roller ever existed, but we were talking Mark IV specifically. Pretty much all of them said they could grind it if I could source a blank though. I thought I struck gold when I found the flat tappet blanks... so I bought 2 extra!

Sorry to hijack your thread Roger.

1.7 arms too

Don't mind me Roger. If anything, I'm jealous of all the fun you're having. That and Tim and I and I'm sure a few others have stacked up a few minutes researching this. The frustrating thing is a company's inventory seems to fluctuate in direct relation to the guy who answers the phone.

Here's a teaser for Tim...I e-mailed a guy about a reverse rotation hydraulic roller cam and his concern wasn't the rev roller; it was about matching my 'other' cam. Sounds promising? We'll see.

Tim ,Greg this post on offshore may be of help.

RR 454 stroking IV with roller cam

Tim,looks like these guys are making the cams just get them ro run 2 extra and bill the other guy

RR cam     

Tim , may be worth a call to Bob the way I read the post he has a batch of 6 made so cost may have come down with the set up charges spread over 6, at best there may be 5 up for sale.
