I'm looking to stroke a 69 350 to 383 and then supercharge it. I have some ideas, but I was wanting to ask opinions and anything I should know going into this. If anyone knows a good stroker kit or individual parts that are best for the build, it'd be great to hear. Would also like to get some opinions on different superchargers and whatnot.

You need to tell us the type of charger you want to run & your desired HP levels.... parts are a lot different between 500 & 1000hp.

Does this have to stay under a stock hood or do you want it exposed?
6-71 style roots chargers look mean & protrude the most from the engine bay, but lack the efficiency of many newer designs.

Eaton type produce a ton of midrange torque & typically fit under a small scoop, but require fuel injection.

Centrifugal chargers (ProCharger/Vortech) can be run with carb or EFI & typically have the most peak HP potential, but do not come on as hard down low.

It all depends on what you want.....

In that case, you will likely want a centrifugal, like a Procharger.

The P-1SC will support approx 750 horsepower.
Go with the intercooled version for best power on pump gas.

You will want to convert your block to 4 bolt mains for durability.

Get a decent stroker kit with forged crank, rods & pistons.
This is not a bad combination & you can run 9-9.25:1 compression on pump gas if tuned properly.

Obviously EFI is the nicest to tune but will cost quite a bit up front.

Spend your money on a good set of heads. This is where the power will come from.
AFR has some very good designs.

Couple this with a mild hydraulic roller cam & you will be set.
I have built quite a few 383's with a 220/230 on a 114 lsa.
It will have a mild lope & still have ample torque to pull a mild gear & an OD trans.
It will work well with a 3.42 gear & manual trans or auto with a 2500 stall converter.
This setup in a 4th gen Camaro went 9's on pump gas.

If I look to put together basically a custom kit (rods, pistons, cam, etc. all from different brands) what kind of specs should I look for that will fit the stock engine? Also, should I be very concerned with the highest quality considering I'm not trying to push insane power numbers? Not looking for the absolute cheapest options, just best bang for the buck, don't have a ton of money to spend, but am fine with waiting and saving to make sure my build is good.
