I downloaded the larger version of the DCR program but for some reason it won't work cause I'm still missing some files. Can somebody who has the program figure out mine out? here's the info:

4.155" bore
3.75" stroke
63cc head
12.5cc dish
.034" deck height
.039"x4.190" head gasket
crane 284 energizer 284@.004" 228*@.050

could you also figure it out with zero deck height and a Comp 30-30 solid nostalgia cam? its specs are 284/291*@.015" 247/254*@.005" 112lsa 108centerline using .012"lash.

thanks

If would be helpful if you could add a few more itesm to the list, like Lobe separation, Lobe centerline, rod length, etc.

Here is a little more data, but not all that you want.

This is on your Crane 282 H06 282 dur 470 lift cam.

Quench Distance .073
Cubic inches 379.918
Static Compression 9.5174

Intake Opens 40 BTDC
Intake closes *62 ABDC
Exhaust opens 72 BBDC
Exhaust closes 30 ATDC

Overlap 70
Total Cam adv. 5.

where's PatKelley when you need him.

5.565" rod
the cam is the energizer 284h 284/284, 228/228, .480/.480", 112*lsa, 111* intake centerline

Sorry, my cylinder bore is 4.155" NOT 4.0155". my mistake.

I get the DCR for the Crane284 combo to be 7.57 (10.069 static)

With the 30-30 cam and a zero deck I get 10.88 static and a DCR of 8.385.
