Well, I pulled the power brakes so thats not an issue. The only #'s I got off the cam are
59062
69 49-95
Couldnt find anything to go with those #'s so I'm not sure but it does not have purple between the lobes like I've seen on most MP cams. Anyway to measure the centerline without a degree wheel?

Yes those are the pistons, I tore the motor down and found those #'s on the sides. The heads I have are thr 915 J heads which most claim are between 71-72-ccs so thats why I'm thinking its at 8.5-1, and would need the heads shaved to boost compression. The other option is to just run it as it is with a thin gasket and save up for same RHS LA-X heads which are 62 cc's which would bring the motor up to where I want it and then use the RHS heads on the stroker buid down the line.
And the I beileve the Crane is the powermax, part H-278-2 with a 222/234 and .467/.494 lift.
Just want something that is going to be much better than the 318 in there now to tide me over until the body and paint is done so I can save up for the stroker build. I minitubbed it and put 325/50 15 DOT drag radials on it, so it looks tough but the 318 just isnt there.
And if I have to buy parts, I'd love to be able to use them on a 408, so something like an air gap intake would be a good thing.
Butch
Shave the j-heads and use the thinner gasket to get the comp up. I have a .528 cam in my warmed up 318 with j-heads, weiand excellerator intake, 750 holley mech sec, headers,msd ign, 727 trans,4200 stall, 3:91 gears. The Dart scoots along rather nicely but i have a 360 block for a 408 build in the works...

I can't think of any easy way, but without power brakes, what do you have to lose? Try it and if you don't like it swap it

Maybe I'll pick one up then, I'm sure I'll get some use out of it. I'm also picking up a burette to cc the heads and see what I'm looking at, seeing as I dont know if they have ever been cut or not. I was also just looking at Hughes 340/360 Whiplash cam on another thread, looks like it might be a good can if I'm stuck with low compression  , soposidly keep cylinder pressure up while still having good size specs for lift and duration.

I would run some magnum heads or at least the RHS style ones.
My combo is:
'77 360 +.040 with 8:1 pistons
uncut 1996 ram van 318 heads with R/T springs & retainers
Summit K6901 218/228 .441/.441 cam (.470/.470 with the 1.6 rockers)
Edelbrock Performer RPM air gap
600 Holley Vacuum Secondary
1 5/8" tti headers
For what it is, it just kicks...the whole trick is ignition timing. I run 16 at idle with 35 total and all in by 2000 rpm. The holley has 65 jets and a 9.5 power valve
Its in a Duster with a 1:1 4-speed and 3.23's. Total tire annihilation at a stab of the throttle under 20 mph in 1st. Its a very fast car for what it is, and has no driveablity concerns whatsoever. I'd be pretty surprised if it didn't make HP in the mid 300's without even trying.
'70 Duster 470hp 340/T56 Magnum/8 3/4 3.23 Sure-Grip

I found this 100ml burette on amazon for $20.
http://www.amazon.com/ACRYLIC-BURET-TEFL...0302&sr=1-1
Here is a 1/2" thick sheet of Polycarbonate 6"x12". for $11. I cut it in 1/2, the 6"x6" size works good covering the chambers, then just drill a hole in it so you can fill the chamber. I think you may need a 1/4" diameter hole if you just do a single hole. The first plate I did used a smaller fill hole and I drilled another 1/16" hole for the air to escape.
http://www.amazon.com/Polycarbonate-Shee...0882&sr=1-1
I used the above plus the burette holder ($9), and a piece of 1/2" tubing so to hold the burette above the fill hole. In the corner of the poly, I drilled about 3/4 through the sheet with a 1/2" drill bit, then heated up the 1/2" tubing with a propane torch, and pressed the tube into the poly sheet. The hot tube will melt the poly and when it cools it will basically be glued into place.
Do this before drilling the fill hole, then install the holder and burette to locate the location of the fill hole.
Here is a photo of the first one I made:

Some tools that make degreeing a cam easier are: Crankshaft turning socket with degree wheel holder: http://www.compperformancegroupstores.co...Code=CrankshaftThe nice thing about this is it makes setting TDC easy, and it slides off when you go the change the cams position, then put it back on and you should not have to restablish TDC again. The cam checker / indicator holder tool http://www.compperformancegroupstores.co...y_Code=CamshaftThis tool replaces the tappet and holds the dial indicator in a steady/fixed position so you can get repeatable results. You will need a 1" travel dial indicator, but to use the tool above, you don't want the the holding attachment on the back of the indicator because it will hit the block. I bought an inexpensive Harbor freight dial indicator, and cur the holder tab off the back and it works fine. The tool above is for degreeing cams with the heads off. With the heads on you would need an adjustable dial indicator holding fixture, and a pushrod or indicator tip extention to reach down to the tappet. With degree wheels, larger is better if the engine is out of the car, but the basic 9" degree wheel will work to degree a cam with the engine in the car. The think to notice when buying a degree wheel is the size of the center hole. Chrysler uses a larger diameter dampner bolt so you need a degree wheel with the large size center hole (the large hole also works with the crankshaft turning tool.) Summit has this 9" wheel for $17 http://www.summitracing.com/parts/CCA-4790/

 But compare cams CAREFULLY
and be REALISTIC on compression, max engine speed
vs. torque power range, converter size (auto trans), gearing/tire size and MOST important vehicle weight!!

Yeah I'm gonna get my compession figured out then go from there. Then I can deciede if I want to mill the heads to get compression into the low 9's or just leave it alone and just run something like the Whiplash cam from Hughes thats made for low comp motors.
It may be all for not anyway, I found some pitting in a cylinder from a little rust that wont hone out. I'm gonna bring the block down to the machine shop to see what they think. If it can be safely run with the pits then I'll put it back together and run it till I can build a bigger motor, if not I'll see if it can be rebored. Its already at .030 so I'll have to see if I can go .040 or .060, its a 73 360 which are soposedly thick walled due to being cast on the same 340 mold back then, and from what I'm told can be bored out quite a bit, but we'll see. So if it needs a rebore then I'll just find some good pistons to get compression up and do it right.
