For everyone's info, I did apologize, not to Dan pesonally, so now, Dan, I do aplogize for being a moron and a horse's [Edited by Moparts - Keep it clean] for 'striking' out after maybe implying I am here to convince myself and others that my car is rarer than it actually may or may not be. I may have even insulted you as one member here said, again, many apologies, sincerely. are we good? I hope so. I respect any one that spends time researching Mopar. I forgot my respect last night and the members have come down hard on me and rightly so...basically runnin' me outta town.

That's not why I posted this question. It's quite obvious its not clear yet , I have read many of the membes say they think, and then concede they think Dan is right, and he may be, GG costs too much to ask personally, he's the expert witness.

Now then, I stated, I use the 1970 factory service manual, the 1970 Mopar parts catalog, and 1970 Barracuda owner's manual to find my answers. I have researched for 19 years, maybe not as hard as others here. In this official factory literature, it states, the N code 383 is a HiPo in 5th VIN digit, and all others are L code. This only leaves two versions, the 2bbl and the 4bbl 330hp. This does it for me, the N in the VIN for engine is only used for one engine, the 335hp Road Runner engine from 1968. No one has convinced me otherwise that there are mutiple N code engines, that goes against everything Mopar printed in their factory literature! Why belive anyone but Mother Mopar.

All info I've ever seen states the 335hp 383 was standard on 'Cuda and Challenger. What members here are saying is a 'Cuda or R/T with an automatic didn't get a super commando/magnum engine. Wrong. For one, I have an article from a book 'Plymouth Barracuda' full of 1970 road tests by different magazines like Road and Track from Road test magazine June 1970 in where there is an automatic 383 'Cuda being tested and it has a SuperCommando pie tin and did the 1320 in 14.4 seconds @ 98.97 mph. Sounds like a hi po motor to me.

Think about it, why would they not install a HP motor in their two performance models, the Ebodies, just because customer ordered an automatic, that makes no sense. The carb certainly didn't give the extra 5 horses.

Also, break out a 1970 Mopar parts catalog if you have one handy. Fuel - section 14-11. The 383 4bbl automatic cars came with both Holleys and Carter's, it depends on shaker hood option, w/ECS, w/out ECS, a/c, no A/C as well as auto or manual (3 & 4 speeds). So there is another false statement provided by one member that only Carter's were installed on automatics. A 383 4BBL auto w/out A/C and w/out ECS came with either a Holley R4368A or a Carter 4732S, as is in my case, I got the Carter 4732S.

All 4bbl 383's had high compression 10.5 to 1 pistons, unless an export model. The 440HP cam and springs makes the extra 5 horses, not the Holly carb found on most 4 speeds.

So, what carb came on a 383 4bbl with a 3 speed? Depends on above.

My N code 383 does not have an HP stamped next to 383 on the pad near distributor hole. This too may be a clue. Always bothered me, kept me curious.

Why am I wrong in quoting Mopar literature directly that all 1970 N codes are HP 383 335hp, & all others (290hp/330hp) are L code? Don't blame the messenger! I'll believe my Mopar literature before believing anyone here or anywhere for that fact. You'd think that the added weight and power loss of the A/C would dictate the added 5 horses was neccessary.

Also, there were 59 2bbl E convs, but, there are also 59 total 4bbl's w/ 3, 4spd, and auto, combined, do the math, 118 total 383's built. It just so happens that adding 36 + 17 + 6 = 59 = the 59 2bbl as well = 118 total.
