True, but this motor is healthy, and its what the customer is trying to get out of it, its a perfect tranny, all the maintenance has been kept on the motor, it was completely stock unmolested, no intake nothing. As for the 400 w/ harness, sorry i have to modify the stock harness to work with his h series. but i will ask if he would like to do that w/o the harness. And if you call places like nad auto etc you can pick a longblock up only for about $500ish.
