I beleive that's a newer short deck block since it has the single row timing chain.

How can you tell ?

Try checking out this link from LC Engineering's website.  It should help you out

FYI, If the motor is 84 or older you can run the factory dual row timing set from an  83 or older. I would also recommend running a 20r head. I am running a 20r head with 22r valves and the newer aluminum rocker assembly. What you end up with is good performance at a low price. If you have questions about running a 20r head hit me up. Some of the 20r heads are more desireable than others.

AR81Toy where are you located. Im in Central Fl. The pic where ur bed is off looks familiar didnt know if u were in fl somewhere. If you are where at and are there any other toyos near yah for sale.

[AR80Toy [OP]]

I'm in Arkansas . gtoy I'll keep that in mind , dont really know what I'm doing just yet , but it is easier to do the stuff since I'm already this far in it .

[gtoyonrocks]

  let me know if you have any questions about the hybrid stuff. It's a really good set up, I'd be more than willing to help you out any way that I can.

[AR80Toy [OP]]

Thanks !!!!!!!!!!!

[gtoyonrocks]

You got it.

[AR80Toy [OP]]

I'm thinking about running what I have and maybe building  a motor on the side .

[gtoyonrocks]

Go hybrid, it's the way to go if your trying to build a motor on a budget. You can build a hybrid for under $1000 bucks. To build a comperable later model engine your going to be in it for between 1500 and 2000 bucks depending on what all you need to replace. I spent 900 on mine, but that was with all new valves, all new hard parts, everything including the dual row timing.

That sounds like a great plan. Just so ya know not all tall deck motors had the dual row timing chains. Your motor (those were pics of your stuff right?) is definately a single row chain.

[AR80Toy [OP]]

I've never seen a Dual Row Chain so I didnt know , gtoy I'll be building on a budget also so hybrid is probably going to be what I'll be building .

guys,  ive seen his motor,  its a 83 block

[AR80Toy [OP]]

What do ya think Glen ? Think I should switch to a dual row or what ?

[DCabTaco]

guys,  ive seen his motor,  its a 83 block

I have an 83 with a newer 85+ block.  Before I know this I had ordered the timing chain for the 83 which was a single row.  The info I got from Ted at enginebuilder is that 81-82 had double while 83-84 had single.  Of course after figuring out that I had a newer block I had to send it back and get the the right one.

[AR80Toy [OP]]

I know, this can get confusing , Is there part #'s on blocks to tell EXACTLY what year they are ?

[gtoyonrocks]

They did put single row timing in some of the early blocks, I promise.

the first 22R's  where in late 1980  and had dual row till mid 1982,    after that they had  the single row chain but it was the identical length  since the block and head where the same

in  mid 84  , for the 1985 model year they introduced  the "laser" block, aka  the short deck block,  these had a shorter timing chain  and CANNOT  use  the dual row chain from the 20R.     
there is a dual row  available  but its PRICEY 


the  "short deck"  aka Laser blocks  have  bolt holes  in different places   to be mounted in different chassis

some of the 84 tall deck blocks  have these same holes  but not many

[79coyotefrg]

yes  from 82-84  they had single row,  but a 20R  timing kit  will bolt right on



and yes David  i would go with a 20R timing kit

[79coyotefrg]

yes and no 

[gtoyonrocks]

Thanks for backing me on that one Glen. I'm running an 82 22r block with a 78 20r head , 22r valvles aluminum rocker assembly and the dual row timing.  There is no better way to make one of these motors perform on a budget.

   man i love me a  hybrid

i ran one  for a long time  till i dropped a exhaust valve at about 7000 rpm     

when i had to bore  the block  the  20R  head wouldnt stay sealed  so i put a ported 22R head on 

[gtoyonrocks]

How do you like that set up??

[AR80Toy [OP]]

Well then since the dual row will bolt up I guess thats what I'll be looking for . Now how hard a job is it changing over to a dual row  ?

[79coyotefrg]

you need  both timing gears, the chain  the  tensioner  and  the guide,   just order a timing chain KIT  for a 79 20R

[79coyotefrg]

How do you like that set up??

if  i ever have to replace this motr it will be a  20/22 hybrd

or  a 1KZ  diesel

[AR80Toy [OP]]

Can anyone get on the LC engineering online catalog  ? I haven't been able to in a couple of days , just wondering if it's my server or the online catalog is down , I get to LC's site but cant go to the catalog .

[79coyotefrg]

dude,  go to Napa    i thought you was poor 

[AR80Toy [OP]]

Napa's kit want come with metal backing guides ( I dont think) , Poor yes , haha , not ordering today , haha .Just been trying to get on that site for a couple of days , can you ?
