I have tried the advance until ping, and settled on about 25 BTDC.  I =
have some type of hot cam (ppo), Crane ignition, HIF-4, and tuned =
exhaust.  I might try going up on the advance more and see what happens.

Well, I finally got my 77B back on the road after my overdrive
transmission fiasco.  Suffice to say that the box is rebuilt, and
shifting merrily along.=20

My attention now turns towards tuning.  Some details:  Weber DGV, Crane
Ignition, Lucas European spec (hot advance curve) dizzy, and Lucas 40KV
Sport coil, old style cast-iron exhaust manifold, with O.E. style

To sum it up, this thing was a dog.  I was afraid to pull along side a
Yugo at a stop light.  A friend who has driven literally dozens of B's
of all vintages, agreed that it was a dog.

I talked to the helpful folks at Britek (from whom I bought above
referenced dizzy and coil).  I had the advance set at 15=B0 BTDC at idle
with the vac advance disconnected and plugged.  Their opinion was that I
needed much more advance, due to the probable advanced wear on my stock
cam.  They suggested as much as 45=B0 if I got no knock.  I questioned
this - specifically with regards to overheating concerns.  The response
was that with the low compression late model engines, that it was not
possible to overheat due to too much advance.

I adjusted the timing to around 30-35=B0, and it did indeed improve =
greatly, and no knock. =20

So, what does the list think.  Did I get good advice, or am I
potentially damaging somthing with this setup?
