The distributor ('73 TVR (TR-6)) in my 2.5L GT-6 has severely worn
bushings. Radial freeplay in the distributor shaft is allowing contact
between the rotor and the distributor cap. I still have the distributor
from the original '71 GT-6 engine. Question #1: is there any
performance benefit of one dist over the other? FWIW, I am running
triple Weber 40DCOEs and Crane XR-700 (probably why my car is still in
use with rotor to cap contact/wear). The TR-6 dist is a Lucas, the GT-6
dist is different in appearance with a different dist cap (Delco?).
Since I have a choice in distributors, I might as well pick the best
one.
I am considering having my dist recurved to increase the total advance.
Question #2: For street use, will I even be able to notice a performance
improvement with a recurved dist? Question #3: When having a
distributor recurved, how does one know if the shop that is doing the
recurving knows what is ideal (short of testing the car on a dyno before
and after)? Any suggestions on places where to have a distributor
recurved and what the typical going rate might be.
In digest mode, thanks in advance.
