Is there any disadvantages to using a 4.150 crank or are you just looking for big cubes.
71 demon stock stroke 440/indy ez-1 running 10.10 @ 132.14 mph in the 1/4 and 6.36 @ 107.46 mph in the 1/8 not in the same weekend but It did it then I sold it. 67 Belvedere that worked it's way in the 10's

I wouldn’t get hung up on a particular power number, but rather...... select the parts that will provide the best driving experience and level of reliability for how the vehicle will primarily be used.
For the description of the anticipated usage, I’d be looking at std port heads and not going too big on the cam.
My choice would be a 440 based 505.

The only disadvantage if you can call it that is all the 4.15 cranks I'm aware of use the stock Mopar rod journal size instead of the 2.2 BBC size. The stock journal size won't clear the bore at 4.15 but the 4.25 will with the 2.2. Kevin

Eagle makes an RB 4.15 crank with the 2.20 journal, along with 6.760 rods to go with it.

Does anyone have any cam recommendations? Somebody stated skip the Hydro Roller, why? I'm not 100% opposed to a solid roller, just rather have not have to adjust the valves 4 times a year. A hyd roller works fine in a big stroker since you don't need a lot of RPM to make power. A 505 with standard port heads will be pretty much finshed by 6500 rpm so it is a good match for a hyd roller cam. If a building a street engine then don't get wrapped up in race engine thinking. A good street engine will have a smooth idle and a bunch of torque down low and if it runs out of steam a little early then so what. How often are you going to unleash 650 hp on the street anyway? This is completely accurate! Getting a little further along, these engines don't need nor do they like higher stalls convertors and deep gears. A 2500 stall works well as does 3.23/3.55/3.54 gears. Overbuild EVERYTHING! A driveshaft with 1350 joints is mandatory as is a pinion yoke with u-bolts. Throw away any hopes of getting an 8 3/4 to live and get a Dana 60. Not sure if something like a Dana Track lock would hold up or not, but I went with a spool to avoid future issues. I make 713 ft./lbs. at 3450 rpm n/a and 885 ft./lbs. with a 150 shot of nitrous. It TESTS EVERYTHING! I've broken lots of stuff in the last two years but drive the car at least twice a week and race it every nice weekend. The work is worth it when you blow off sportbikes and high end latemodel stuff!

The work is worth it when you blow off sportbikes and high end latemodel stuff! What cam was in your build that made 713 ft/lb? I agree on not going crazy deep with gears if you have the torque to pull a 3.54 or 3.73 through the traps. Being a hot rod, of course I want a rough idle that's what they make vacuum pumps for lol. I was hoping to keep stall speeds down as well. I have not yet purchased anything other than a 2 early 70's 440 block to have on the shelf. I'm still undecided on 512 or 528 kit and the TF 240 head vs the 270... Yes this is a street driven car that will have a set of slicks bolted on once in a while for track days but it is not a race car. I know I'm walking a fine line there on this build and all it takes is a few wrong choices to turn this into a car that can be temperamental on the street.

I know I'm walking a fine line there on this build and all it takes is a few wrong choices to turn this into a car that can be temperamental on the street. The link to my cam is listed above. Once I taught my wife how the shifter works, she was surprised at how easy it was to drive! I didn't want a race car, either, but rather something I could enjoy on a regular basis. IMO, unless you are getting on the interstate frequently or driving long distances, O/D really isn't needed. I drive my car as far as 40/50 miles out of town, but when we take it to Heartland Park or Tulsa Raceway Park, I trailer it. Kinda hard to fit pit bike, coolers, chairs and popup in the trunk.

GY3! I'm in OKC, what are the chances I could swing by over some weekend to examine your build? The depending on the final gear choice, the OD would likely be needed, would travel an easy 100 miles on freeway in a day just to get to and from any event or just from one side of the city to the other and back.
If I stuck with a 3.54 or 3.73 it would be tolerable without OD Absolutely! You are more than welcome to stop by any time. I'm on the East side of Wichita. I'll PM you my address and contact info.

Thanks A friend of mine built the trans, he put some Diesel trans parts in the a518/46rh trans, billet servos & a heavier spring for the OD set up, the converter is from PATC, custom built for my set up, 4000 stall,lock up. To make the trans fit it takes some hammering on some spots on the tunnel & the torsion bar cross member has to be thinned & cut on, had to build a custom trans x member. Cope Racing Transmissions should be able to help you if you decide to go this way.
