The 400 in my 78 Newport is the sweetest running V8 I've experienced. It runs well, and gets reasonably good fuel economy. That 400 starts well summer or winter with NO block heater. I know 400s get a bad rap but I don't think it is all deserved. They are, after all, the largest bore Mopar ever produced in a V8. ----- Original Message ----- From: "jsadowski" <jsadowski@xxxxxxx> To: <mailing-list@xxxxxxxxxxxxxxxx> Sent: Tuesday, December 23, 2003 11:55 PM Subject: Re: IML: 413 vs 400 engine swap-Why? I once owned a 77 NYB that had a 400 CI & I was never really thrilled with the way that car ran. Perhaps, minus the Lean Burn, It may have been fine. One thing I would question is, what kind of rebuild can you get for $500? You may be going to extra lengths for an engine that may have problems. John
