Re: New GM Engine???
Don't let merc get their hands on it!!!
I won't pay $200k per side! |
Re: New GM Engine???
Cool Video....thats their 12.5cr engine. Runs about $13k I think.Carb to oil pan. Demon carb. Their 600hp engine goes for a grand less, same engine... less compression & a cam/carb change...so they say.
They recently redid the valve covers though. Another site said they no longer are red, or have the 572 & Chevrolet on them. Just a bow tie & I think their chrome now. I liked the red ones... |

Re: New GM Engine???
So, for you engine guys - what would it take to "marinize" something like that, and would it be worth it?

More clearance between piston and cylinder...ring ends get more clearance too Blower pistons are a must with that much power expected out of it...and a high quality set of rings too. More clearance in the rod bearings for oil flow to remove heat from the bearings. Re balancing the rotating assy...If its anything like the ZZ502 it will rattle it's self to death in no time. If your looking for a 1000hp blower motor you better plunk down the cash for top of the line internals...not to mention a beefy aftermarket block...There is no such thing as a cheap marine blower motor making 700+hp. I not slamming this bad assed crate motor, but it is not for powerboats...I read alot about people blowing up the 502s running them at the track. I know nothing about detailed marine engine building but learned a bit while having mine built. Oh, and we did'nt even talk cams and valve train yet.... |
Re: New GM Engine???
That was me? Sounds like my pre-40's cocky-ness. I think someone wanted to drop a blower on the 600hp lower cr one in that thread.

Re: New GM Engine???
They did a test in one of the magazines on this 720 hp version and all they had to do was retard the timing slightly. I don't remember how much but I think it was on 2-4 degrees. Motor ran fine and still made almost the same power.
This shouldn't be to suprising. Alot of engine builders set them up at 11:1 on pump fuel being 91 oct. |

FWIW...I have the zz502's in my boat, but they have a few upgrades :cool: :cool: One of them being Inconel valves and different cam and springs. They haven't vibrated themselves to death yet!!! :rolleyes: :D :drink: and I don't exactly go easy on them. |
Re: New GM Engine???
They put the 620 h.p. version in a car last night on "RIDES" on TLC. once they got it tuned right it seemed to run real sweet.

Re: New GM Engine???
were getting ready to possibly drop a set of the 620hp model into a top gun at this point it doesn`t look like were going to have any problems

That would be a sweet setup for that money if they had reliability!!! |
