Still have original black paint and no corrosion

Looking for offers. This stuff needs to go

..

Those won't fit on mark IV 454 blocks will they

They should, however, you will need a different gasket than the ones I have

What cam are the 575 heads set up for? Those are flat tappet right? Like 560 lift.

I'm pretty sure the 575 sci has a pretty mild flat tappet.

That engine would have a hydraulic roller, not a flat tapped.

Really....

:pacifier:

..

Sorry guys but ALL FOUR serial ranges of the 575sci list the same camshaft and same lifter, and they are flat tappet. Not roller.

Just to clarify
The 575 SCI (ALL Serial ranges)
1991-1996 Gen IV/V 600 SC
1998 Gen VI bobtail 600 SC
1993-1998 800 SC
All run the Crane/ Merc # 491-818870 cam which is a a hydraulic flat tappet.

That doesn't mean that your engine wasn't changed at some point, but if they were on a 100% factory stock 575sci they are set up for flat tappet. If that was a factory roller engine I would be trying to buy these already. I need something to bolt on and go just in case my other engine is not finished by the time the weather turns.....

These are off a bone stock 575SCI running a flat tappet cam. I can do a valve job and a spring change on them if that is what someone is looking for.

Sorry for the misinformation. I thought that it being fuel injected (SCi) that it would have been a hydraulic roller set up. A hydraulic roller is what's in Mercury Racing's specification.

525.00 shipped to 49675?

$100 should cover shipping to most areas of the country

spring bump

still available

What exhaust bolt pattern?

Standard BBC

These were complete and ready to run other than the 100 hrs of use, correct? If so, would you do $575 including shipping to 34683?
Thanks,
Rick

Still avail?

Yes, they are still available. I am not going to take your offer PQ, sorry.

I have a really nice Dean Nickerson Dominator that I bought from another OSO member..Supposed to be new..Not sure if he meant new as in never ran..or new as in rebuilt..Would you be interested in a trade of some sort. I live right across the bridge in Henderson so no shipping..

Will you take $600 and you cover shipping?

I will take $600+ the actual shipping

I have no need for a carb. Thanks though

Sold. Thanks OSO and motor
