Budget 318 build

Mike Jones only has one .904 hyd on his website the bottom one
H440D64307 DC 260 for comparison
265 @.004 284
256° @.006 269
246 @.008 260
202° @.050 212 newer grind may be 221/228 some were 221/221 over the years
120 @ 200 115
64 @ 275 DC 260 is 42

.307″ lobe lift
.461″ 1.5
.491″ 1.6
The 20 degree shorter duration obliterates the need to over advance It closes about 10 degrees earlier than the Direct Connection Cam
Most posters do not have a camdoc to show the whole profile but note how this cam is 50% bigger than the DC cam at .275 lift which is about where the port flow demand is the greatest
Howard or Bullet can grind something similar but IDK about their .200 or .300 numbers
Shelf cam look at a Lunati Voodoo 256-260 intake
Lunati, Howard and Bullet use the .006 number for comparison
as you can see the .050 number is meaningless except for degreeing the cam
.200 gives a hint
so short .006 big .200 is what works on a low compression mopar
even that DC cam is superior to a 256 Comp chevy lobe which closes the intake at around 54 degrees ABDC @ .006 - Jones would be the same but JOnes is shorter at .004 and it is where the valve actually closes that counts (The DC cam is more like a 268 comp)
comp does not have a cam that works best 4 U
