I have not topped her out yet, got the boat to 76mph, max rpm on these motors are 6000. Im hoping the 28lab props will get me the rpm. bblads tweaked them but they do not think i will see that rpm with these props, might have to get 27's

How many rpm's were they turning at 76? What happened to your stock motors?

stock motors were sold, as far as rpm's i didnt get a good look. this weekend i"m going to try to top her out

Very Nice! Really clean installation.

Is this the engine?

Do you have any problem finding 91 octane? How do they sound compared to the orginal 6.2's?

I bet they really wake-up that 292! Let us know what you can get out of her.

4mulafstech yes that is the engine, i had the plenum covers painted blue and the valve covers powder coated, as far as the sound, when i have the exhaust open, at idle and when its running it sounds really good you can hear the cam. as far as the power its like having a new boat. the midrange is superb, i have not topped here out yet. Im going to see this weekend. i run 93 octane it all the time.

Can't wait to hear results. This is firming up my decision for a 292 with scorpions

I got up to 76 on the gps and she still was not done, i"m hoping 80. powerboat tested the 2002 292 with scorpions and ran 76mph those motors were rated at 360-370.

Sounds great, good luck!

Did you have to trim or shorten the Quick&Quite Corsa Y-pipes to fit the Stainless Marine exhaust manifolds?

no they fit with no problem

You do know that you can not get these engines in a new 292 and they are totaly different from stock 6.2s 377 ci ?
