I have everything up at the machine shop waiting its turn in line. Here is the cam Muscle Motors recommended for my build: http://www.compcams.com/Company/CC/cam-specs/Details.aspx?csid=708&sb=2Once he starts machine work I'll take out my motor and bring him the heads. Then figure out the rocker set up I will end up with. I also scored a used set of TTI's and installed them already. They cut down my ET slightly and also brought up my mph. Going from a car that runs mid 14's to this stroker set up is going to be interesting.

Holley owns Quick Fuel Technologies and BG Fuel Systems (Demon). Except for the Street Demon, all of the four-barrel carbs being sold by the three companies are based on the same Holley design. If you can work on a Holley you can work on the other two.
As far as rockers go, stockers are light and cheap. There have been many many bigblocks built with the .509 lift cam and stock rockers. Your suggested cam is in that ballpark for lift and that's where I'd go. Most cheap aluminum rockers are cheap and don't work well or for long. You may want to find AndyF's article on bigblock rockers, seems like some of them don't fit too well. Many have had good luck with Harland Sharps, I believe Hughes sells the plain bearing set. Otherwise I'd stick to known brands.

Small update, new 400 block was given to the machine shop to check out. Have not heard back yet from them. I ordered my strange dana 60 from dr. diff and my dad picked it up while I was stuck at the hospital. Went with 3.54's since it will have enough power that I don't need 3.73's really. Now I'm trying to figure out what skid plate I need to buy for the oil pan I bought( http://www.manciniracing.com/mabheap.html ). I imagine I should get the 1966-1969 hemi one even though that pan is technically for 70-71 ebodys: http://www.manciniracing.com/kskpl.htmlI am about to order the Carter Mechanical Strip Super fuel pump, ARP bolt kit, and hotchkis subframe connectors from Summit Racing. After that I just will need my heads done. Had a question on those too though : https://board.moparts.org/ubbthreads/show...e=4#Post8419233I know when I send them off to get CNC (probably next winter) they will have to go to 10* locks/retainers. Someone on that thread said I should be fine with what I have and a flat tappet cam.... Again my health has put me behind but I'm still chugging away at this. Have been in the hospital 3-4 weeks since the end of December . But new treatment option might turn things around.

Devin, best wishes on the health deal. Not fun. On the rockers, it would be well worth checking into the use of a 1.6 rocker for a couple of reasons. First, stock rockers don't deliver a full 1.5 lift, and although a lot of guys have used them successfully, since you have to buy rockers, you might as well step up to some good ones, adjust them once, and be done. Then you won't have to worry about having one fail. The extra lift of a 1.6 rocker will help in the Hp department, and the rpm range for your build will be very low, so not much worry about problems there.

I suppose I could add those on when I get them cnc'd next winter. Everyone is saying the stockers will work right now. On another thread I have, a guy states that the 7* locks are good enough. But will be going to 10's on that.

Well I have the motor back and painted up. Just need to take the old one out and put the new one in. Got the Brad Penn oil and my wix oil filter for break in. Specs on everything and some random stuff: 470" Stroker kit from muscle motors CNC ported stealth heads from MCH (numbers below) Cam: xe274h-10 Xtreme Energy XE274H Hydraulic Flat Tappet Camshaft & Lifter Kit Lift: .488''/.491'' Duration: 274°/286° Stock stamped rockers (will upgrade in the future, but will work fine with the cam I have) Edelbrock Performer RPM 750 holley carb (figured an intake and carb will be easier to replace than taking the heads off again so I spent the money on that. May go EFI) Carter Strip Super mechanical fuel pump ProSport SFI Harmonic Balancer Cometic head gasket .051 thickness Can't recall what the compression ratio should be Hemi 4 speed Centerforce clutch TTI 3 inch headers Strange 60 w/ 3.54 gears 295-50-15's I know the rockers and intake/carb set up are holding me back now. What should I put in the 750 for now as far as jets and what not? I have a full jet kit, just don't know what a good estimate would be to throw in. What kind of spark plug does everyone like? As money allows, I will upgrade those things. My new k frame, pulleys, fan just got done getting powdercoated so I'll pick them up tomorrow. Ordered a new steering gear box that should be here in a couple weeks from Firm Feel. Resealed the hemi 4 speed I bought off of here and it looked good inside. Still need to check if I need to mess with the bellhousing alignment, but have a Browell tool for that so it should be easy. Will still need to put in the strange 60 and get a driveshaft made through Dr. Diff once I get the measurements (unless someone knows what a 68 b body with a hemi 4 speed and strange 60 dana length will need to be).

The flow numbers on those heads are encouraging They outflowed the CNC ported Eddy RPM Jeff at MCH did for me back when I have a customer who bought a set of those heads two years ago, I'm building him 511 C.I. pump gas stroker motor now and it will need a decent set of heads like that(his aren't ported, yet) to make the power he wants Thanks for posting your update

I listened to your wise advise after getting my linkage straightened out. While working on it the UPS guy dropped off something and I set it down in front of my car. Well that box took a mile long trip with me and the car. I kept hearing a noise that was scaring me, but I figured out that it was just that box haha. Later gave my gf's oldest son a ride that I promised him after he "helped" install the motor a few months ago. He told her I was the fastest driver in the world lol (I maybe got up to 35 mph). Once the sun went down I ran around a bit more, but need to put my hood back on still. My old motor sounded good with my cutouts opened, but this motor is on a whole nother level. While swapping it rearends I needed to change brake lines. Well the rear brake fluid in the master cylinder was nasty! So I cleaned it out and gravity bled them. Now the brakes work better than before. Next on the list to buy is disc brakes, rockers and maybe cam someday. But I sign into Moparts today and a member listed a SSBC disc brake setup for $250, so they're on their way up to me. There is a huge get together Friday night near me that has a dyno, so might see what it does.
