[QUOTE="bobkyle2, post: 157815, member: 579"] Yeah, 400's over heat if you try to run non-400 heads on them and you don't drill steam ports. 400's use simease cylinders. and there are steam ports in the heads. If you run them on the street you need to drill steam ports. This engine won't be a driver, Just race only. On a 400 you need to worry about the block also..... On a 400 you don't want a 4bolt main, You want to buy a 2 bolt main. The 4bolt main 400's have weak casted blocks... The 2bolts are very tough. [/QUOTE]
