Cams for 318's
.004 DC is 20 degrees longer on the seat 284-264 = 20
Any suggestion on the chain for a tight budget? Maybe Sealed Power KT3160S?
START A NEW THREAD DANIEL like best new chain on a very tight budget
DAniel Do you have an automatic
if so you need the correct 4 bbl trans linkage or the hyd kit
Your question post 101
"Can I just compare duration at @.050? K6900 is close with the specs you posted?"
I think you can see from the posts above why you can't for drieveability, dynamic compression
you sorta can for top end horsepower
from the comparison post and the 340 thread
DC 260 measured 261 @.008 but it's 269 @.006 if you want to compare with comp, lunati,
.004 or SAE Jones is 264 and DC 260 is 284 @.004 20 degrees different
That's about a 10 degree earlier intake close-
IC is really important for low compression motors
checking at .006 instead of .004
@.006 Jones 254 and DC 260 is 269 degrees
Jones takes 10 degrees to go .002 the DC 260 15 degrees to go .002
The Howard is going to be similar to the Jones (but worse below .004)
The Lunati may be in between the Jones and the DC
The rest get worse and worse as you can see
@.006 DC 260" is 15 degrees longer than the Jones 269-254 = 15
however at
@.275 lobe lift DC 260 is 42 whereas the Jones is 64 @.275
50% bigger where the power is
