I look at it this way, my current RPM is 4600. With better heads, intake and cam I will be able to spin more RPM, plus with more power who knows what i'll get out of it?? I'd be happy with 55 on GPS

I love u man. U got to get a life man. Most real people ask if they are not sure about something. Unlike u I know I'm not an expert. Since your the best SHOW me where I said I was and expert. Problem is u can't. Since you are ignorant u have to find ways to put others down. This poor fella asked about some help and u got to go ****ing up the thread. Find a big truck open the hood put your head in and SLAM it shut. U got problems you **** for brains.

OK, I'm just gonna ask....please stop.

We are all here because we love boating and speed. We are also here to help each other.

That's why I joined OSO

I'm done. Problem is Slow ***** (SB) will never stop till he gets the last word in. He has problems. Good luck with the engine this winter. Keep posted how it turns out.

I run a 350ho 330hp vortec motor with a holley 650 carb performer, rpm intake, msd ignition, roller rockers, and revolution marine wet exchaust and I picked up about 7 to 10 mph on a 21 ft hull 24 degrees with a ss prop 23 pitch. good luck

I just picked up a Vortec 350 short block for $80!!!

My Saturday night just got more interesting...

I believe I need to change the flywheel in order to do this engine swap, right?

Everything else should bolt right up.....

Flywheel and starter I believe. Is there still a spot for the fuel pump on those late engines?
Was it a boat engine? Changing the cam?

If you have a earlier shortblock in good running order, I don't see any reason the Vortec shortblock will be of benefit. IMHO.

Other than that the Vortec will have the hr roller lifter stuff.It will cost more than the $80 you spent on that short block to get that for your 88 motor
Those parts aren't a ton of $$$ new from GM though.
