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.
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
exhaust.
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° 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° 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°, and it did indeed improve power
greatly, and no knock.
So, what does the list think. Did I get good advice, or am I
potentially damaging somthing with this setup?
Regards,
Chris Delling
