64 CUTLASS KEN

I read another thread on this, but I didnt want to hijack his thread. It did help alot, but I have a few other questions about what I have. My block number up front "396021 F". the heads are cast with a big "E" in the corner, the back of the block has "72 CFO" (the O could be something else) and on the trans: near the tailshaft "3-70 q" or a "b", not sure there either. and on the tag it reads "70-OC 87112" im planning on stuffin this thing in my 64 cutlass convertible. any other input or info from others who have done the same is quite welcome!

thanks a million! this site RULES!

trans is 1970.

The year of the block will be on the driver's side below the #1 spark plug on a flat pad sticking out.

Where can I get a set of those cool bronze spark plugs?

They must add about 15bhp, if they look that cool.

K, I wrote down what was on the little pad below the #1 and it is stamped "30X141685" I know the "3" is the olds the "0" is for 1970, but what is the "X" for? and from my first post, what transmission do I have? I dont know how to tell.

As all have said before we need pic's. With the 455, all info points to be a '70 engine. I'm thinking the trans is a short shaft from '70 also. May be the matching trans to the engine. Should be a nice mover.

On a 1970 Olds, X was used for the Kansas City assembly plant.

The 1970 OC TH-400 was used on 455 2-barrel Delta 88, Custom, Royale models (5400-6600 series). Should be a long tail shaft.

So I have a chance to get a 455 with C heads. Is that worth getting rather than this one I have been asking about with E heads? the one with C heads the guy wants 200 more for than the one I have been looking at with the E heads

Is the "C" head engine a 2bl or 4bl ?????
I'm leaning towards the "E" head engine.

the C heads motor has the 4 barrel and the E heads have the two barrel. The C heads come from a 69 block and the E heads are off a 70 block. I bought both of them as the price was good. should I mix the two with sertain parts? and someone said something about a switch pitch trans on the 1969 engine. I have never heard of that. what the heck is "switch the pitch" ???

A switch pitch trans means the torque converter stall speed can be changed between two preset RPMs. A typical stock switch pitch stall RPM would be 1300 in the low stall mode and 2200 in high stall. It's like having a high stall converter to launch harder due to the torque mulitiplication but then having a low stall converter for minimum slip at higher speeds. So you'd have two converters in one basically.

If you're using that 1970 trans you don't have a switch pitch. They were made from about 1964 1/2 to 1967.

the '70 trans isnt the one I was told might be one, I have a 69 motor that they said it might. It has a longer tail shaft, but I wouldnt know what to look for. I dont know if this one came with the motor or not.

C heads are pretty good that is what edelbrock bases their head design off of however the E heads are better. Without my book idk because I really only know the small blocks right off the top of my head
