    My little bro has 1800 for the 6.2 out of a cucv i gave him, got lucky to it looks new when he took it apart. What does it cost tho?? He is trying to build a beefed up 6.2 and is running out of cash fast. Down the road it will have a turbo if it matters.

    Also, was wondering, the 6.2 will be bolted to a 465. i think max rpm is 3600. Please let me know if i am wrong. What will happen if the clutch blowes or something where there is no load on the motor and rpms fly up? Will it live or ???? is there a way to keep this from killing the 6.2?

    As always thanks mike

    I just had my engine rebuilt, i had new pistons already. the following is a list of what i had done, bore to .030 over sleave the # 8 cylinder, balance rotating assembly to inclde te flex plate and balancer, new rod bolts, new lifters, new push rods, regrind crank .010 and re-nitride, new bearings, rings, and a valve job. with new springs. all of this totaled up to 3300 US Dollars. Since then he has raised his prices to 4200 dollars for the same work. I also had my own gaskets and valve seals, and installed my own heads. so the cost doesnt include that or the ARP studs i used. If he did the short block himself and picked up pistons off ebay he might be able to squeak by with a 2000 dollar rebuild

    They sure do, and I've found the govenor on mine twice now. It just de-fuels and falls on it's face a little...

    3600 rpm sounds like 9000 with a 6.2 :crazy:

    3600 rpm supposedly, although I'm sure it varies a little.

    Ill third that. While I worked as a diesel and heavy equipment mechanic we dealt with diesels in the 11 to 14 litre range that were governed to 2,200 rpm.

    After putting the 6.2 in my Blazer and getting it up to highway speed the first time I thought it was going to self destruct!
