1966 Mopar 273 2bbl Intake Casting Nos
 

I -emailed the Division 4 tech (Trey). They left off the 2bbl casting numbers for 1966 and 1967. This is what I got back.

The Engine Blueprint Guide will be updated to read intake manifold casting number for 1966 Dodge 180 hp 273 cubic inch engine will be: 2536560.

Now, I had looked through the other years of 273s and some 318 engines and found these casting numbers:

1968-9 273-2 intake casting number 2536559
1969 318-2 intake casting number 2468960
1970-2 318-2 intake casting number 2951185,3698431
1973-on 318-2 intake casting number 3698431

My question to those that may know about these things, are there two intakes with sequential numbers (559 and 560), or is one the casting number and one the part number? I know Chrysler usually had the casting and part numbers one digit apart for many parts back then. I let them know the casting number was missing on the 1967 blueprint spec as well. I'm pretty sure the 560 number is the service part number. I found that in a Larry Shepard book on SB Mopars and other places.

I've ordered the CD of the factory Chrysler parts book and service manual for 1966 Dodges on Rock Auto. That should be a good reference for what parts were used and the part numbers. It won't give me casting numbers unless there is a photo of the part, and those aren't necessarily accurate to the year.

did you ask mr wong about these part numbers?

Re: 1966 Mopar 273 2bbl Intake Casting Nos
 

No, I thought I'd do more research before bugging Mr. Wong. I talked to Ron Ortiz today. He had a couple of 2bbl intakes and then it digressed into chatting about the Gators. Since the college where I teach is closed the week of the Gators, I'm considering making a quick run down to check out the action (as a spectator). I'd probably just go on Thursday when the Stock and SS guys are there and might have a little time.

use one of those LD340

Re: 1966 Mopar 273 2bbl Intake Casting Nos
 

I can't afford an LD340 now, the prices have gone up a lot in the last few months. It wouldn't work on the 273. The ports are even bigger than the LD4B and those ports are bigger than the ports on my 920 heads.

Rag71, thanks for the tip. Arkansas might be close enough to go pick it up. Most of the others I've seen were too far away.

The 1966 and 1967 casting numbers are announced today on www.nhraracer.com

Dwight, please explain to me just how a combo can be raced for YEARS without an approved intake manifold number in the guide? And what about the 65 cars?

Billy, move over, you have company in the one year only intake manifold combo. Everything I found online said the 2536560 p/n was the part number, not the casting number. Well, at least I have the casting to look for. I haven't seen one yet.

Re: 1966 Mopar 273 2bbl Intake Casting Nos
 

They finally put the 252 manifold in the books after tearing me down for the 10-15th time with my 65 car. There were no intake numbers before that. I don't see why the manifolds are not approved from 64-68 they are all the same with different casting numbers. The early manifolds have the 5/16 bolt holes, though.

Re: 1966 Mopar 273 2bbl Intake Casting Nos
 

I got the CD of the 1966 Chrysler parts book. Yep, just as I thought, the 2536560 is the part number, not the casting number. I think that means I will never find one. Billy you are one up on me if I want to run the 2bbl engine? Maybe I can get NHRA to approve the 340 sixpack manifold with the end carb spots blocked off? Billy would love that! LOL!

See if you can get a hold of Galen Govier to see if he can clear up this mess between casting numbers and part numbers

Re: 1966 Mopar 273 2bbl Intake Casting Nos
 

I don't know how to get in touch with Galen. I'm not sure if his white book is a better reference than the Chrysler parts book. I'm thinking no. At this point I'll just try to find any 2bbl intake, preferably the 559 casting. I think that is the correct one. Like Paul said, it would make sense if they made all of them legal. I have a line on a 1971 single plane for a reasonable price, but my battery on my truck needed replaced. I got that done today, got the truck inspected as well. I'll try to pick it up after I get back from the Gators. Just going on Thursday as far as I know. The college where I teach is closed next week for Spring Break. I hope it doesn't rain next week.

Re: 1966 Mopar 273 2bbl Intake Casting Nos
 

I have a 65 Plymouth with a 273-2 barrel, single plane type. I can get the number tomorrow. I think the casting number is one number off the part number, don't know which way. Too bad Chrysler didn't do a 273 4 barrel on the b-bodys, I'd be tempted to race that car. The 273 feels more powerful than a 318.
