88 inch cam choice

[sfmichael]

Got a buddy with a 02 roadking, stayed 88" used some 06 heads with a  fresh valve job. .030 hg. Andrews 48 cam, rineheart true duals. 95-96 tq and 86-87 hp.
  All  the power is in "fun zone"  for most riders,  2-5k rpms. Smooth,  quite.

The guy is going with the Andrews 37 cams and keeping the 88 inch. He bought a set of 103 heads and milling them .030 and a thinner steel head gasket. D&D fat cat pipe. Budget build.

I did a bunch of cam testing years ago now on the 88 incher bike was a 05 so beehive springs  here are the results. EX was a  KW 2-1-2 with V&H classic round mufflers . As you can see it was a test but in the end not much changed if the right cam was used .. Customer was a bit of a odd one and wanted all of the cams installed and tested .. He settled on the 509 .  Hard to say that one was far better than the next the 37/510 cam where the lowest of the bunch tested in that engine.

Andrews 48   82/90

Andrews 26   80/87

Andrews 26   82/88  + 4

Andrews 37   85/84

S&S  509      77/91

S&S  510      78/82

The tork on the 37 510 cam is the highest and that is what the ridder would feel, just depends were that tork would be, 3500 rpm or so I would think

[HD/Wrench]

No the 510 was the lowest tq and the 37 the runner up for that ribbon.. Those cams really need more CI and compression than a stock 88 has to offer . But overall they are all very close . Curve wise the 37/510 where not bad the 510 in fact had a great curve just not big numbers

As always, good info Steve.
