I am new to tuning carburetors and i am building a motor for my 1985 mustang gt convertible.

I am looking for what i should do for a base tune on my holly 570 street avenger carburetor.

The carb is originally from a custom boat with a chevy 350 and i had it running on the stock 5.0 f.i. HO motor but never got it to work good.

The new motor's setup is, 1988 factory 302 block, Factory 1985 Rotating assembly with new rings and bearings, arp main bolts, head bolts, rocker studs and rod bolts. It is running a Comp 35-226-3 Cam and lifters:

Cam Specs:
lift: .512, .512
231,231 duration @.050
110 lsa
Springs:
comp 972-16
Pushrods:
Comp 3/8"
Rocker arms:
Comp 17044-16

Heads:
Factory 1967 351w
Intake valve: 1.870
Exhaust valve: 1.570
Compression ratio: ~9.4:1

Distributor:
Pertronix Flamethrower ignitor II

Intake Manifold:
Weiand Stealth Intake (non-polished)

The car will weigh between 2500 and 2800 lbs with a wct5 from a 1986 svo and factory 8" rear end with a 3.27:1 Ratio
it will be running premium only. And i want it to be as driveable as possible given the cam. I dont want it to break 350hp and it will not be running slicks or likely even performance tires.


I am looking for what would be a good starting place in terms of jet sizes, secondary spring, squirter sizes, squirter cam sizes, power valve, everything.

I appreciate help thank you.

Additionally i am aware of the downsides of this build and do not need to be reminded lol This is just the engine i am making to get the car running.
