HELP.. need INFO on 80's roller engine

a friend wants to get a roller engine.. he has a line on one...


he wants to know what year is the BAD roller engines.. or what year is the GOOD engines to get.

5.0 roller engine..

i told him late 80;s but not sure the year range.. please help.. engine might be gone tomorrow..

thanks

 

Anything 87-92 is the best bet. 86 has the flat tops and crap heads which cause issues with piston to valve clearances. 87-92 have forged pistons. Also, the 93-95 engines are decent too, but come with hyperpathetic pistons. Look for a grey oil pan as opposed to black. The grey pans generally mean forged slugs.

 

thanks

i passed the info to him.. he said in the junkyard he went to, there was 5 roller engines from the late 80's still in cars...

im so excited now... i want to go get one...

 

Send me one as payment for all the hot info LOL

 

Tell him to remember the 50 oz balance.
So his 28 oz stuff will have to go.
Also, if he has a manual tranny, he will have fab a cable or hydraulic clutch.
The late blocks have no provision for mechanical linkage.

could just run an atuomatic right??

thats what i was gonna do

 

Yep, sure can.

 

I was reading some Stang restoration mags today and found a bracket for late blocks and early manual trannys. It bolts to the side of the late block using 2 existing bosses. Then it has a boss welded to it in the correct position to replicate a mounting point for stock linkage.
The kit runs about 60 bux.
Fwiw

Im pretty sure dmhines had to use one of those on his roller block for his toploader.

 

Personally, I would like to try a hydraulic clutch once.
They work so well on late model cars...
No headaches.
