CF engine code - UPDATED INFORMATION


So, my 64 Acadian Beaumont Sport Deluxe was originally a 6 cyl car, but over the years someone swapped in a 283, and when I Googled the CF engine code on the block, I got this (various sources, the last one and the one I am liking the best, from Chevellestuff.com):

CodeYearc.i.c.transhpcarbmodel
CF1958283m/t2304truck/1271/Omega
CF1960283m/t1702truck/1100/Impala
CF1961283--4full size/Impala
CF1962283m/t, 4 spd--Chevy II/Impala
CF1964283m/t1952Chevelle

Since my motor is 2bbl, do you think the original 6 was replaced by the 64 Chevelle V8, or earlier 283, or what?

Thanks,

Dave

RE: CF engine code


Federally the open PCV system was introduced for 49 States and Canada for the 1963 models; earlier ones would have simply used a road draft tube. California got the open PCV system starting with 1961 models though. Also the truck and regular full-size passenger cars would have used rams horn exhaust manifolds which don't work on A-body cars like Chevelles or Beaumonts. It isn't as though somebody couldn't have just change out the manifolds, but to make it easier it would have been best to swap in the engine straight from another 64. They probably went straight with a donor 64 engine. Do you have the full engine code handy?

Do the cylinder heads have the "Witches Hat", pointy symbol on each face??

That was the Power Pack head that ended up on all 195 H.P. 283's

That was the best 283 head, casting dates will tell the rest.

Carb # can be a clue.

Thanks
Randy

Best way to tell what engine you've got is by looking at the casting #, in conjunction with your CF stamping.  Cylinder heads, manifolds, etc can easily be changed.   

See if you can get the casting #, I think it should be on the block likely behind the passenger cylinder head.

I just noticed your other pictures and the cylinder heads are not era correct as they have accessory holes.

These were first used on the 1969 model year Engines so are an instant giveaway.

They possibly are from an 80's 305 H.0. Engine as any others would lower compression.

Correct style heads are cheap and easy to find if you are looking for the original look.

Thanks
Randy

Engine code on front pad is T0920CF, so built in Tonawanda, Sept. 20th.

I will check later to see if I can make out the engine casting number (right now, the passenger side of my '64 is 2" away from my '56 in the garage, and I will not be taking it outside for a while). Also, I will be changing valve covers and air cleaner so I will check head casting numbers, intake manifold number and carb number then.

Casting mark on the front of the heads is the fat "L" as shown below, bottom left (from http://www.crankshaftcoalition.com/wiki/SBC_cylinder_head_identification )
Casting Marks sbc heads.jpg

If the data above, and from http://www.nastyz28.com/sbchevy/sbch.php are correct, then these are likely '68-'76 heads, not from a 283 no

But I will continue to try to chase it all down ...

Thanks for all the info, guys!

Dave

It might be a Chevrolet engine   not a Pontiac  confuse

I am certain it is a Chevy motor, not a Canadian Pontiac motor.

Given Cam's info, it did not come out of a passenger car, though - the exhaust manifolds are not the rams horns but look to be correct for A-body car.

Casting # is on the Drivers side of block at rear, should be able to see it from the top of engine, on flange where trans bolts to engine

Yep but I cannot lean over that far to see it right now, given placement of cars in garage ... pretty soon I will take her outside and check it ...

OK I have pulled the valve covers and the cylinder head casting number is 3927185, again, engine code is CF and exhaust manifolds are correct for early A-body ... so, what does that narrow down my motor to?

Thanks,
Dave

Since you've got the valve covers off and got the casting #, can you also get us the date code casting?  I did an extremely quick search, and it looks like 3927185 was used 1968-1973.  Again, that was an extremely quick search so the info is not gospel.

Model year 1969-to 73 or 74, 327 or 307.

70 cc, lower compression than a regular 283.

Not ideal on a 283.

Thanks
Randy

Well poop. So some unknown person in the past swapped in a SBC V-8 (most likely a 64 Nova 283) and then some other unknown person in the past stuck on those crappy heads ... well at least it runs fine, idles like a cat purring, will never win any drag race, but it glides smoothly on with the PG and so I guess I will live with it quite happily, given its mission to be a nice cruiser ...

CF engine code - UPDATED INFORMATION


I finally got a chance to look at the back of the motor on the passenger side, where the casting number should be, all I could see is these great big raised letters:

T5

Any more help on identifying what my motor came out of?

Thanks,

Dave
