New block

[flipper35]

I am getting a new (another Mopar 360, everything is set up for this block.) block so I can do this engine right. Some things I didn't have the time or money to do when I bought the car.

I need some people with more experience to tell me if this is OK or not.

Here is what I was thinking.

Have the block bored .30 over (not done on the current engine)

KB pistons @ 10.5:1 flat top w/ reliefs (current cast 9.0:1)

Have the whole rotating mass balanced internally so I can use a lightweight flywheel. (externally balanced right now)

Dart or Commando Aluminum heads. (has excelent heads now, but are iron which aren't good for the higher compression)

Roller rockers, undecided on brand.

Undecided on the intake.

Will have to ditch the Holley 4160 @ 600cfm vac secondary.

Will need a new cam to match the new heads and CR. I have a new Mopar 320/320 513/513 108 degree centerline.

Stock cranks are good for about 650hp, but the rods are good for only about 7000rpm.

I found a place in Yuma for the parts and machine work.

What am I missing, what should I change, is it worth the effort. I can take my time and buy the pieces as I have the extra money. These reccomendations were from local people that should be in the know, but . . .

An identical engine to my current one was dynoed at 406hp@5300rpm and 435ft/lbs@4600 rpm
