Congrats Glenn, I'm anxious to see your motor this summer.

Edelbrock Vic Jr
Holley 850 dp Ignition:
MSD 6AL
I have the intake, carb, ignition, and recently the rockers. I'll be getting the cam and lifters around Feb. the heads hopefully spring, the rotating assembly fall, and the machine work/assembly done in the winter.
I suspect the motor will make ~230HP and 265TQ

Why not build a 406 Alex? It will actually cost less because besides the normal stuff, no additional machine work will be neccessary. Actually, I guess you have to factor in the cost of a 400 block to that, but you know what they say.......there is no replacement for displacement! Unless you go with an internally balanced crank (which you can also do on a 406,I did) you will have to buy a new balancer and flexplate anyways, so its not like you will save any money there by using your old stuff.
I'd do a 400+ cid only if I would use an aftermarket block and the added cost would ad another year to the buildup. The only added machine work would be clearance required for the rotating assembly which I am going to do myself.
I played with Dyno2000 and found that the larger displacement motors did not gain much in terms of HP but they gained in TQ, I figured ~530 would already be to much and could not justify the added $3000 cost of an aftermarket block.
If when the motor is done I’m still not satisfied I could still build a 427...454 short block. I think my radial tires will hate me with the 383.
BTW how many blocks did you check before finding a useable 400?

Ummmmm, isn't more torque the main goal here?
With that motor, more than your radials will hate you! If you plan on driving it hard,and I know you will,your entire drivetrain will hate you!
I went through way too many 400 blocks than I care to remember to find a good, virgin block to work from!
I'm going for HP at 6500+rpm and TQ over 500. I want to hear that sb scream. If Torque was the main goal I'd use a smaller cc head RV cam and 600carb that should get big TQ# @ low rpm but I won't be going anywhere.

Currently a TH400 and in the future a 4L80E, Trans will be ok. Rear end should be able to live as long as I don't use slicks.
Also, received my nice speed demon today, I had mentioned at Lasfest that I wanted one well Santa was nice and had it delivered today, little late but oh well.

So how was your Xmas?
Those are 1.7 ratio rockers in the pic above so you can be sure the cam will be mild
