440 wedge?

[1969CoronetR/T]

I visited my friend at his work today with my Coronet. My '71 Demon's engine is being rebuilt at the shop. The owner came out and told me that my Coronet is a 440 wedge, which is the same as a 426 Hemi block less the heads. I always thought that the 440 was a bored out 383, but he claims that is not so due to the water pump position and such. So, my questions are is there two engines variety for the 1969 Coronet R/T? A 440 wedge and a 440 (regular)? And what would be the difference in power?
Thanks,
Mark

All "B" & "RB" blocks are "wedge" motors...except the Hemi...water pumps are all interchangeable... between the motors, just some have inlet on other side.

440 has longer stroke than 383, plus bore is different, block is taller than 383 because of stroke difference

Basically, the "owner" is an idiot...there is only 1 440 block (wedge)...it's all the same

Hemi blocks are not the same as wedge blocks. If its not a hemi, its a wedge.This guys rebuilding your engine? You might want to go somewhere else. What shop is this so I don't go there."B"blocks - 361,383,400 "RB" blocks - 413,426(wedge),440 Hemi blocks - 426.

HEMI blocks are the same as 440 except the cross bolt mains, the upper row of head bolts and the motor mount style and location. Those are the major differences.

440/383

The 413-426 and 440 are all classified as RB or raised "B" block engines (includes the 426 Hemi and wedge). The 383 is a plain "B" or low block "B" engine (and so are the older 350-anyone besides me old enough to remember those?- and 361s) There is an early version of the 383 that is an RB version but it has all but disappeared from the planet! Bottom line is that your 440 is like all the other 440 and they're "wedge" engines as compared to Hemi engines. The phrase was developed when we had 426 wedge engines that look like your 440 and 426 Hemi engines that do not, back in 1964-5. We needed a way to classify them so we'd be clear when communicating.
Hope this helps.

The term wedge and Hemi are the combustion chamber designs.
361, 383, 400 are all low block "B" engines
early 383, 413, 426's, 440 are all raised blocks "RB"
I don't know what block the 1958 350's were though. Thinking "B" as I recall the 2x4 intake being able to be used on later 383's, but don't hold me to that.

Thanks for the answers. THe friend is using the 'owners' shop as the owner is a restorer. The friend is doing minor reopair to the engine as the camshaft is rusted and needs replaced and the engine rebuilt later. I will be taking it to another machine shop to rebuild and add a stroker kit after the summer (if the engine lasts). dla4567, the restorer is not at fault as he is not touching the motor, he just had to throw his two cents around and the friend could did not want to contradict him as he has a free space to work. Although I will have Jay at Domination Chassis do the engine work and Pittsburgh Crankshaft do the machining.

Cool, hope everything goes well. you should post some pics of your car. The 69 Coronet is one of my favorites.

Accidently posted a picture of my wife's Benelli M2 automatic with my DPMS 7.62 carbine. MEant to post this picture of the aforementioned Demon:

I don't know what block the 1958 350's were though

They are "B" engines. They had four bolt valve covers, but were otherwise similar to the rest of the "B" family. My best friend had one ('58 Fury) in High School (1964) and other than being a little rough in the body the car was good and wicked fast for it's size! I can't imagine a '58 Chevy or Ford staying close to it back in the day. My '58 Impala convertible wouldn't and it was a four speed! We had it over 130 more than once, and when those two AFB's opened you better have it pointed in the direction you wanted to go. Not nearly as strong as a 440 RR or R/T, but this was 1964! Besides, with those big fins NOBODY expected it to be fast. Lots of $$$ changed hands with that car! It was rated at 305 HP and that HAD to be conservative....It was fun!

1969 Coronet R/T

Ditto on the R/T. That yellow one is the only one I've ever seen besides mine with the 6 pack set-up! Too cool! I like the big (those are 15" right?) Chrome Magnum 500s!!

Why are there Wisconsin plates on your car? Your avatar says you live in Pennsylvania

 

[scotts74birds]

[Meep-Meep]

What size AFB's are you running and are they 1:1 or progressive? What cam/compression combo?

THese are the sellers photos. It is now sitting in my warehouse in Pittsburgh and desperately needs clayed, polished, and waxed from being stored all winter. The sellers photos are too hard to pass up as the green grass and the pale yellow contrast the black R/T stripe. I will post pictures of the Demon and Coronet together soon.

Oh, well you are right, the car looks awesome.
