    I've been considering some performance mods for my K25 w/350, but the engine is old (original '75 vintage, HD emissions) and I may want to rebuild/replace the block before I try to boost performance very much.

    The Goodwrench shortblock engines look like a good deal, considering they are new blocks. The basic shortblock with heads is about $1200US, and you can get the HP version with Vortec heads for about $2300US.

    For a 4x4 truck, would the Vortec-equipped HP block make sense if you got the right cam to go with it? GMC has a 330 hp version of the Vortec-equipped block that includes the cam, manifold and carburetor, but I assume its tuned more for the rpm of a car than a truck.

    Anybody used the Goodwrench engines and had good/bad results?

    I have installed several of them, all with good results. Alot cheaper than rebuilding.

    I just installed a gm goodwrench crate engine last weekend in my 1980 3/4 ton gmc pickup. Its a long block, not a short block, includes the valve train, oil pan, valve covers, timing chain cover, and oil pump.

    I paid $1200 + $100 core from a local gm dealer for a 350 cu in engine with a 4 bolt main. Brand spanking new engine, runs like a top, why mess around with a rebuilt shortblock for $300 less? And if it fails within 3 years, the dealer will install the new engine themselves, no additional work for me.

    I'm happy as a clam, my truck drives like a new rig. Good luck.

    I would stay with the older iron. It will more than likely have a very high nickle content and 4 bolt mains. A stock rebuild is not a lot of money to have done. Use the older block and find a machine shop to do the work.
