My son has a 1998 GMC- C1500- 2wd- with a 305 V8 engine, his engine is on it's last legs. he was at Autozone the other day, and saw remanufactured engines that could be ordered thru them. There are 2 Surefire engines, a VCMC & a DCMC. Anybody ever buy one?, and if you did, are they OK? They also have a direct replacement engine, no name was specified. All 3 carry a 3 year warranty, he's trying to get prices for all 3, but, the price is not posted on the web.
