In the 58 model year, the De Soto Firesweep had a 350 2-barrel big block; Firedome, Fireflite and Adventurer had 361's with either 2-barrel, 4-barrel or two 4-barrel intakes.
If your engine's dual quad intake is OEM to that motor, and it's a De Soto engine, then it's definitely a 361 (58 Plymouth Fury offered a dual quad 350, but not Dodge or De Soto). But the factory dual quad B intake will fit either a 361 or a 350 - or, for that matter, any 383 or 400 of any year (the only exception being the RB 383 that was a 59-only, Chrysler-only engine).
A 361 is just a small-bore 383. Any 383-400 distributor will work in a 1958 361 engine - Chrysler electronic, Mallory Unilite, whatever . . . .

If it's the original 361 2x4 it was rated at 345hp@5000rpm and 400ftlbs of torque. That year the hp 361 was also available with electronic fuel injection rated at 355hp. Unfortunately, the fuel injection setup was plagued with problems and they were all recalled and the motors were retrofitted with 2x4's. Dave

Funny thing about that 345 hp rating for the 58 Adventurer - (it's the same horsepower rating as the 57 Adventurer with a 345 hemi, BTW) - is not only that the De Soto engine somehow had 40 more horsepower than the dual quad 350 Plymouth Fury when the only difference between the two engines was 11 cubic inches, but the De Soto also had 25 more horsepower than a 58 Dodge Super D-500 which had the same dual-quad 361 engine as the De Soto Adventurer.

The differences in horsepower is easy to explain, they correspond almost exactly to the differences in prices:
Plymouth Fury 2 door hardtop $2927
Dodge Regal Lance 2 door hardtop $3245
DeSoto Adventurer 2 door hardtop $4071

That's what's my Standard Catalog of Chrysler lists... 1958 Firesweeps had the 350 2bbls. All other models were 361s.

You are correct, I missed the Firesweep page completly when I made my list?
