Funny, a 67 442 on ebay has a 455 and this is why according to seller.

The original 442 engine was replaced with a 455 with full ram air intake. The replacement was made due to the fact that the original 442 engines were known to cause concerns and it was very common with this model.





Apparently it was swapped for everyone's best interest!

 

Ebay= Fact.... did you not know that? geeezzzz

 

Assuming same rear end, I'd put money on a 67 442 taking a 70 442. The 455 had more power and torque, but the 70 body was heavier. This is with all stock, equal drivers, and probably more so on automatics with the switch pitch in the 67. I think the quarter times were damn close.

 

I really dont know a lot about oldsmobiles but I thought the 400s up through 67 were fine, the e blocks right, then in 68 or 69 the. G block came out and this mighthave had some issues because of the way it got 400 cubes ( longer stroke?) And accordingly even these motors put up some good numbers... but I know nothing of this first hand just listening to my much better informed "ELDERS" lol . There is plenty of fertilizer floating on "he pay and pay"

If I ever get my project done and I am still able to lift a wrench, I would love to geta 66_67 vert 4 speed... varooooommmmm

 

The E blocks much better motor than the G block
E block almost square in that bore and stroke on or around 4 inches
G block no where near those desirable numbers - 3.8 something bore and over 4 inch stroke


E blocks dominated C class in NHRA

 

The 67 400 is junk,the 66 is much better.

 

Please educate me & explain why. Thanks.

 

I think you mean much better junk because perhaps the 3x2's caused More rapid "concerns" ahemm!

 

Sounds like "Bozo" has come up with a real good explanation as to why his 442 doesn't have an original engine. To anyone dumb enough to believe him!

 

Are you this serious all of the time. You would think that me being a 66 guy that would possibly be a joke? I've said many times that 66 was the last year for Olds. My man Oldsmaniac got it.

 

I thought the 67s may have been made in*Tuscaloosa.

If they were that would a great reason they are junk. I don't go to Tuscaloosa for any reason.

 

When I was 19 I had a 67 4 spd and that big car was FAST! I didnt know much about cars then and I was hard on that car, I raced it alot on the street, only lost one race to a Hurst equipted built Rambler American. The red white and blue one? 390, fast little car beat me by a fender length. I ended up spinning main bearings on the hwy. I dont even know what gear it had, maybe a 3.90 i dont know, all i know is it was fast. I think the E block 400 is a great engine, I just abused that one too much. Sure wish I had it now. Thats the first motor i ever rebuilt. I put a Crane Fireball 3/4 race cam LOL, it ran good.

My old '67 4-4-2 was factory 4-speed with 3.90 gears.
Back in the day, we street raced almost every night and I was not easy on that car.
For a "junk" engine, that "E" block sure " took a lickin' and kept on tickin'".

Also had a '69 W-30 that lived a similar life. Equally durable engine.
The "G" block didn't rev quite as quickly as the '67 "E" block, but it was respectable.
The "G" blocks with the longer stroke were more of a torque engine.

The rumor I heard was that Oldsmobile redesigned it this way since
a lot of people were buying 4-4-2's for towing boats and campers.
Maybe true, maybe not.

 

The '65-7 E-blocks were by no means junk -- far from it. They were the best-revving big-blocks made by Oldsmobile, due to their short stroke and low piston mass (as compared to the 425).

The 400 was redesigned in 1968 and utilized a very small 3.875 bore vs. an outlandish 4.25 stroke, yielding the G-block, a lower-revving torque-monster. The reasoning behind this was likely two-fold: the long stroke enabled the 400 to share its expensive crank forging with the new-for-'68 455, and the small bore reduced quench area in the combustion chamber to reduce emissions.


If you want to go racing, you're probably better off with the E, but then again the G made a butt-load of torque. You just don't want to spin it much beyond 5-5500 rpm.


Hope this helps.

 

65s were B blocks, dont lump us in with those E block boat anchors.

 

Same engine, though, except for lifter diameter and bank angle, no?

 

Don't even go there,a 45* bank angle 65 400 is worthless.

 

He's fishing,he knows better. He's just looking for a response from me.

 

 

Both 400 4" and 425 4.125" pistons weigh the same per the fsm.

 

But some guy on the internet said ...

 

No, seriously, are there other differences?

 

Only basic difference is the heads,66 had B heads and 67 had C heads. 66 was available with 3X2 tri carb option. That is all.

 

Cool!

 

Now I am at a loss... what should I do? I have a 66 L69 and a 67 W30.... Should I swap the "B's" and the "C's" ... and the L69 set-up with the single four ram air..... Decisions, decisions.... Well, after a 60 second brain fart, I decided to leave well enough alone.......
