The off season work on Barney has begun with earnest.
I've ran the stock CCC carb, distributor, and ECM on my car for the whole 7 years that I've had this 383 in the car and it has ran great. It's got many wins in it's class with the SCCA autocross, a Street Modified championship, a third place trophy in it's debut at the SCCA Solo Nationals, and several very successful track day events where it surprised a lot of people over the past couple of years.
During the later part of this season though, at our autox events held on larger more open courses...the car kept getting beat by the newer LS powered cars in my class. I wasn't sure what to do about it until the last event of the season which was held on our local tight technical course where I won over those same cars by over a second. I was getting beat by an upper RPM horsepower deficiency. It was time for a change...
This engine has always built fantastic torque down low, but the ECM would pick up noise from the knock sensor and start pulling timing out up around 4250 RPM which would kill the upper end horsepower.
I researched putting a MPFI setup on this engine but ultimately decided I could swap in a LS1 cheaper than to put EFI on this engine correctly...and I'm not really interested in doing that at least right now. So I started researching ignition boxes and found this super cool MSD unit #6530 for sale locally at a good price, so I picked it up. A friend had a re-man quadajet left over from his car he didn't need anymore and I picked up a new MSD #85551 distributor and started the swap to pull the CCC out and put the MSD ignition box in.
My heater core sprung a leak last fall so it needed to be replaced as well, seemed like a good time to do it all at once.
My goal is to get the complete CCC harness out in one piece, put the ignition box somewhere under the dash and use the CCC grommet to run the MSD harness back to the engine. The distributor has had the mechanical advance locked out and is set back in place with the rotor pointed at the #1 spark plug wire and a basic tune has been loaded into the programmable MSD box.
I sent the carb off to a friend to have him make sure it is 100% ready to run so that when it's bolted on and the ignition box is fired off, my ignition problems should be solved and hopefully I can realize the true potential of this engine.
