When it is complete, are you sure it will not give a CR500 a good run for the money? 
Those are nice, centerlines?
I don't even know, for sure... but,I'm pretty sure they are.
I hope this isn't a stupid question. But, are you having the engine and tranny either rebuilt or upgraded to somthing different? Like maybe replaceing with a LS1 carb version? Just currious.
No I did not see those pics. 
Yeah, Its a 400 bored .040 over 13.5:1 dome pistions,phat cam.... All that jazz ... I will be building it.
Transmission is a th350, was built by B&M about 15 years ago. Very few passes on it,but its got all the harndend shafts and gears,shift kit... Its sat since i quit racing..Hope shes still good.

Have you talked to an engine shop about the 400 block? I heard that the 400 small block has over heating issues. I wanted to build a 406 useing the 400 small block. Not sure how true it is. 
I have a 1969 350 4 bolt main block on my bench just waiting to be started.

If you run them on the street you need to drill steam ports. This engine won't be a driver, Just race only.Have you talked to an engine shop about the 400 block?

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.
Would it work if you drilled and tapped your block to make it a 4 bolt? Using good steel caps. Or would that just weaken it?
Yeah, To improve on the 2 bolt design you would need to have the block sonic checked And they can drill where they feel it would help.... I don't plan on going over 750hp.. And i know a few guys that run them around there. I will be well under that. And i'll use a stud girdle.
What do you plan on doing with that truck? Making a Monster truck out of it? I would be happy getting 450hp out of the 383. If I build it. Wow 750hp
