Late 88 with a 89+ block factory? Possible?

[JDMMA70]

So my question is could my car have come factory with a 89+ block? I know they started making 89's in August of 88. My car was built in June of 88. While changing a hose i noticed my engine block was the later casting, and i went back and looked at all the records of the car, and it never shows it getting a new engine or any kind. It does show a rebuild done by a shop in the Woodlands, TX. However the stuff listed is just whatd youd expect rings, bearings, machining, etc. doesnt list a new block or core engine. The number on the block matches the number on the service records.

So is it possible that Late 88's came with the 89+ block? Or does my car have some hidden history somewhere in its life of having recieved a used engine.

Thanks

Doubt it. As 89's come with the baby block (from what i've seen) Hi Poodles.

Maybe the old owner brought in a core? lol

Well thats not 100% true Bluechulappa has the original motor in his car and its the later casting. His build date is November of 88.

Shrug.

Your call what happened here; as long as it helps you sleep at night.

Some of the transition parts are a bit odd... Do you have the lower redline? Wonder if it has the old or new crank...

My 88 had an 89+ block (the one without the big strange core plug)

It was the original engine, 6m crank too.

Blocks didn't change at the same time cranks did. Cranks changed for 1990 model year (08/89), blocks (apparently) changed earlier than this.

No i have the 6M crank, the block is the same as 89+ blocks. I have the older style coolant rail as well.

6M crank motors Pre89 and from what ive seen early and mid 89's had 6500rpms redline.

Your motor may have been swapped is it a Late 89?

my 87t will not rev past the redline. not sure what motor ive got as mine was swapped 5 years ago when i got it.

Yeah non of my '89 Supra's had a 7m crank.. my '90's did though..

 

[Jeff Lange]

No 89 with the original engine should have a 7M crank.
