I have a 360 that was put into a 70 Duster....... I have the block numbers
4006830 360, that tells me it a La360, 1976 to 1980. I searched for the numbers on the front of the block where the head bolts on and found #s 9w360. Now if I'm correct that makes it a 1979, 360 build in Windsor.
2 questions, did i decode it correctly and what manifold and carb combo should I go with. Remember, not a race car, just a driver!

Thanks, Mark
 
Most any dual plane manifold would be suitable for an otherwise stock engine. A carb in the 600-650 range with vacuum secondaries would be the carb to go with.

If you are building up the engine with more compression and a bigger cam you can't go wrong with an Edelbrock Performer RPM (or RPM Air-Gap) manifold. A 650 to 750 would then be a better carb choice.

Hey Mark,
Where did you find the decoding information (what the numbers mean?) I pulled some numbers off the intake and am curious.

Thanks!

Along with gear ratio?
Can you get ahold of a T-Q in good shape? A small one would be better for a driver. Being the engine is a 76 - 80, the cam is small.
Otherwise, what dgc333 said.
 
Mymopar only has numbers listed, i think, up to 74 so I continued poking around and found Auto Hobby digest.....
 
I use the info stored in my brain.
Believe it or not, the basic information below the head is the same from back in the mid-'50s clear up into 2000 and later.
Similar information is also located on the distributor pad on B engines and the top valley pad on RB engines.
Pure simplicity at it's finest.

The only real information that you need is the year and displacement, all else is redundant.

HM340 is 1972 340 built at Mound Road assembly.

When finding a letter preceding the assembly plant, it correlates to a year from 1965 through 1973 and reads, as follows:

A 1965
B 1966
C 1967
D 1968
E 1969
F 1970
G 1971
H 1972
J 1973

Remember that Chrysler started using numbers in 1973, so 1973 can be either J or 3 and the letter 'I' is skipped in the sequence.

Pre 1965 also uses an alphabetical letter to indicate the year, but I haven't memorized those. :)

The numeric list is as follows;

0 is '80, '90, '00
1 is '81, '91, '01
2 is '82, 92, '02
3 is '73, '83, '93
4 is '74, '84 '94
5 is '75,'85, '95
6 is '76, '86, '96
7 is '77, '87, '97
8 is '78, '88, '98
9 is '79. '89, '99
