They're a very good engine shop. Their bread and butter is stock style rebuilds. Website says they've done over 60k rebuilds, and have a 36k mile warranty. I've had them do the 5.0 in my 95 GT and the 3.8 that went into my mom's pontiac. We daily drove those for years and never had any issues. This place lists $1996 for a stock style 351 cleveland long block rebuild. The $2990 price is for the upgraded one with a little more cajones. That price also includes a kit of gaskets to put the extras on the outside.On almost $3K for a complete rebuilt long block - that's really not bad if the builder does it right. I'd take that all day long. I have a CJ short block with the small chamber/large port heads in the machine shop now, and I expect to pay more than that. Granted, I'm doing screw-in studs and new forged pistons, but it'll be worth it.
$3K for machine work, clean and labor to rebuild is a good deal.
I figure I'll probably be in it for another grand after I add in the extras like fluids, plugs, motor mounts, a new water pump and fuel pump. It doesn't feel right to me to have those parts off already and go back putting 50yr old clapped out ones on a brand new motor.
And probably at this time, my dreams of a TKX will just have to wait. Its pretty much free to put back in the C6. The full TKX swap kit is just shy of $7k. There's not enough snow around here this time of year for that sort of snowballing.
