We did the Rb/511/trick flow 240/2 inch tti- 650 hp. See Dewayne for Cam, we also had him check the heads. our compression is 10.74
440 Source lightweight stroker kit. we have an M1 intake as well as the Trick flow, it was deep port matched by hughs. holley ultra xp 950 ( that was a mistake, carb was bad out of the box etc), Had Jim Parr precision carbs build us an 850 thats flowing about 930cfm. starts nice, idles nice for the cam , street/strip set up. cam is 630/630 258/264@50 110 ( if memory serves, see Dewayne. How quick is that combo and in what weight car?

AndyF has a 400 and 440 stroker piston selection chart in the tech section that is helpful.
I built a 505" based 440 and it works really well. That said, I would probably use the shorter, stiffer 400 block if I were to do it again and start from scratch. It helps with space if you are dumping it in a A body, too!
You won't go wrong with either choice IMO.

I have a 440-448 in the car now with a .557 cam, TF 240 heads, Victor intake. Has been a best of 10.49, but typically a 10.70's car. I have both 400 and 440 blocks. If I go the 400 route I'd need pushrods, intake and a distributor, which isn't a deal breaker. My gut tells me to go the 400 route since the blocks seem to be stronger than the 440, plus should be a little easier to work on in my duster. However at the same time, the 440 route would be a little cheaper and I would think that block would be fine for my power level, but I don't want to build it and down the road the block break and I'd second guess myself.

The distributor issue; isnt a big deal. Ive used RB distributors in all my LD's. Some diatributors my require the spacer to be opened up some but that's not usually a big deal.
Ok

Since you already have the RB intake and dist, and know how the RB package fits in your car, I’d just do a 505.

I am building a street/strip 69 GTX and want to go 10.30's so I figure I need about 700 hp. I am anal, and I did not want to put that much hp in a stock block so I bought a new RB "the block". It had some issues, but hopefully Bischoff (BES) has them solved. My motor is in finally assembly and will be done hopefully this week. I will report dyno results as soon as I have them.
I assume I will be at 3800/3900 lbs. I do have 30 inch street tires, too much gear (4.56) but I also have a Gear Vendors overdrive.
As I mentioned, the block is an aftermarket "the block". It is 0.030" over so it is a 505 with 4.25 inch stroke. The block can support a lot more overbore and can easily be a 540 cubic inch plus but I stayed conservative. I ended up with Trick Flow 270 heads and a Dwayne Porter solid roller. My goal is a real 700 hp - figure I need that to get so much weight down the track at 10.30's.
