It has the dual timing chain. The numbr on the block is 0387100. Im gonna order gasket kit for it and need to know what year it is. Also what brand do yall think is the best

 

dual chain 22r's were 81-82 at least in trucks, unless it's been converted.

 

fel-pro!!

xxxtreme hit the nail right on the head with the dual timing chain info

 

also, its common for people to drop a 20r head on a 22r and make it a hybrid engine w/ dual timing chain, right?

might wanna give the head a look and make sure its a 22r head rather then a 20r

 

ya i thought it was only 20r heads that had dual row chains

 

to verify the year of your engine you need to show the intake ports on the right side of the head..pre 84 were one shape and 85(or 84) were different.
can not put a 20R head on a later block, something about the piston dome being different between early and late..

any 22R can have dual row timing chains...when doing a timing chain it is a common(and smart) upgrade to go to dual row....

 

83-84 is rather simple to convert, later 85-95 ones aren't. Only one person makes the dual row timing cover for the late model 22r/22re. That's LCE.

 

What he said.

I just might build one of those dual chain engines I have
