What do you guys think is the best first step to boosting BHP to a stock 383? Performance exhaust ordered so just thinking about the next performance project, tuning? carbs? Inlet? Headers? Turbo ??
Ok great so first step is to find an MSD distributer that suits and adjust the timing etc to get the most from it.
Time to do my research.
Something like this?

I disagree on the choke, I was very skeptical on buying the carb recommended by a pro (no choke) but have learned that my motor definitely doesn't need a choke. Both my car and the car I just bought for my daughter don't seem to like chokes at all. I live in Ohio and have no problems starting in 20 degree weather.Re-curving is getting dist. setup for timing advance to come in a little quicker & limiting how far it goes. I'd go with a different intake first after that. Good carb in picture but not for a street car IMO, especially no choke on it, probably jetted wrong too.
Oh excellent, the previous owner has an electronic insert rotor replacing the points so is that what you mean? or a full system like this ? https://www.summitracing.com/int/parts/dcc-3690428/overview/Don't think a MSD billet distrib is needed. A Mopar Perf electronic conversion kit is plenty good if you don't have a killer race motor (money spent better elsewhere). If you have access to a qualified auto electronics mechanic, he can limit the mechanical advance in the distributor and then put some more initial timing in, then figure out what total timing the motor wants (likely 32* - 34*). You need a timing tape to be able to read the total timing with the timing light.

Sorry I'm poor on this end of the vehicle, can you tell from these photos what I have?I was talking about the setup in your link. Do you have an electonic "box" that's driven by the modified distrib? Boy, didn't realize how much the price has gone up on those kits. The stuff in my garage might be worth more than I realized.
The carb you linked is a double pumper, whether or not you decide on a double pumper or vacuum secondary will depend on a few things. If planning on running an automatic, street gears, heavy car, etc then you'll likely want a vacuum secondary. If more towards drag racing where your running steeper gears, a motor that can really propel the car or have a lighter car than maybe the double pumper.
Saying that a race carb isn't best for the street seams odd to me because the biggest difference is more adjustability or tuning options. I've ran a Holley Avenger and a street Demon on my car and the Q series Quickfuel is far better on the street than both of the others. Just know your driving style and your car and go from there. I run a 750 double pumper on my 456 with 3:55s and a 6 speed standard, having tried the others this is the carb for me.

ok cool, I have the electronic replacement insert for the dist installed so that must be a different solution, so I need one of these babies in my first stage of power improvement? - https://www.summitracing.com/int/parts/sum-850004/overview/make/chryslerAlextucker, don't see an electronic control unit (ECU) in there.
