I've been looking for a donor engine for my 68' Firebird and came across a 69 Grand Prix SJ with the origional engine. From what I've seen this 428 engine had some pretty impressive HP and Torque numbers from the factory. The engine appears to be all intact and the owner says it ran when it was parked. "They probably all do." Anyways he won't sell the engine seperate and wants $2500 for it. Any opinions why I should or shouldn't buy it. I have no use for the Grand Prix body. My bird has a Pontiac 350 in it and I am wanting something that would be very fun to drive. Thanks for any opinions anyone gives.
