Not true guys I already commented on this
Who made the first DC cams? RAcer Brown?
Even Chet Herbert and Crower had many .904 lobes back in the day
UD Harold did some for Lunati then Ultradine but not for the earlier Comp line The Lunati's were quieter than the comp and made more power...
combustion chamber and piston top was the same for all I doubt that carb tuning or ignition timing would have made much differences
Some competitors have said they would make changes based on what the know now, even as to cam advance which would have helped many but they chose their advance...
very streetable lobe profile but would have lots of overlap flow thru so maybe not so great gas mileage and lots of ex heat This test did not care about overlap also since running 110 it was low on compression so an early intake closing really helps
great video by the winner and also from 2ed place
too much spin here but
DV based his cam on his SBF database, he is currently working on BBC I'm surprised he did as well as he did. Jones is correct on the combo compression is too high for pump gas and too low for E85 Jones did not want to take the time for the mismatched build
BTW I paid the...
Not exactly Isky had his one and only (catalog) .904 cam for our 62 413 great consistent cam then Racer Brown who ran faster or slower inconsistent
The Isky cam is still good for dialing in chassis and would make a good bracket cam but obsolete today and gone from the catalog
even if you do not have an overdrive you can put in a lock up converter (pump, shaft, valvebody)
I built a 998 for my daughters pacer trans from a AMC 360 cop car Transgo kit and Continental converter (RIP)
just use machinest dye to check valves
valve grind compound leaves a line- right
but the valve gets bigger with heat and the line is no longer in the right place
you are not building a model A or Chevy stoveblolt
rumble got it right several pages ago
me- stroked 340
but wait- that's a 360
much easier parts availability and on the street cu in rule
cast cranks do not break and are a lot cheaper than forged
most power per dollar starts with a magnum takeout
look at it another way and start with heads
or...
