There are two ways you can go here.
You can simply lock out the mech advance.
Or you can limit the mech advance travel stop to about 10deg of travel.
This will allow a 24-26deg inital base timing at idle.
and a total mechanical advance of 340-36deg at max mech advance.
use a 1 medium and 1 light mech advnnce spring combo once the mech advance travel is limited.
The stock GM vac advance pot on your distributor will not be
right for you engine. Get the crane fully adjustable vac advance with
the stop limit for the vac advance and read the crane directions on how to set it up correctly for vac adv rate and limit.
Th700r4 high stall converter.
Don;t be temped to buy one of the cheap "2600stall" converters
They are just a restalled GM 2000 stall converter
All they do is bend the intermal fines over more to increase the
stall. the stall and idle will not be right for your cam.
This is a very inefficient way to get increased converter stall.
Get a real deal high stall lock up converter.
based on a 245MM converter size.
3500-4000 real stall.
ya get what you pay for. These th700r4 converters perform.
They have a fully function HD lock up clutch so the th700 trans
performs correctly in OD and retains full street ability.
get some 4.10's
