Mercs tells you all this BS about the recommended HRS & Cost of this rebuilt Mercs tells you this but the real cost is about $78,000.00 for the set of rebuilt maybe out of all the 1075 out there 6 pairs have been rebuilt for the $25,000.00 like Mercs says.

I would go with someone like Zul's were you get 150+ hard hrs on his motors with out any BS.

Jeff,

I have a friend here in Houston who just picked up two naturally aspirated 1000HP engines. I don’t know the builder but he has gotten 300-400 hours out of them before. I can get more information if you would like.

Thanks but he wants strictly Merc.

LMAO I guess you have not had much influence on him yet!

You got that right.... Vyper motors and Arnesons

I am in this delima right now. I have been on the phone quite a bit the last couple of days so let me tell you what the Merc Rep read out of the manual to me. Valve train at 50-70 hrs, basically a topend, Total rebuild at 100-120 hrs.
As far as CRC goes, there are couple corrections there as well. First those were not 1075's , more like the 1200's that will be at the Miami show. I believe Mike is going to have a set in one of the outerlimits in the water. Yes they did make a full season, but they were freshened before the worlds in Destin. This is still pretty amazing the way they were run in CRC. Also the Merc rep told me that they required 110 oct, The rpm's would be raised to 6500, I am pretty certain that CRC was able to turn ALOT more R's than this though.
I am not saying all this to promote Merc. Just wanted to make sure everyone was on the same page.
Now my question for everyone since I need to make a tough decision myself. WHY would the mercs not last at least as long as any other builder with the same HP. They use very good parts, the valve train has been improved greatly from the 900SC, they have a Good fuel system and the electronics from what I have been told are very good.
Help, please.

whats the main differences between the 1075 and the new 1200, does it require higher octane, is it a 557 ci, costs, rpm's etc.

Yes, Outerlimits is going to have Pyburn's 47 GTX in the water with the new 1200's.

I have several friends with 1075's in their MTI's. 2 of them have had timing belt problem, belt tensioned problems plus an assortment of other issues. One of them just sent his back to Merc for Rebuilds. They have approx 125 hrs on them. The bill went from the origional quote of $45k to over $75k. These motors were not blown up either. This was a "maintenence" rebuild! For that much you could have bought 5 Kick A$$ long blocks!

I thought Bill was putting the BIG Vortec motors in.
