Is my 85 Block A Roller Or Flat Tappet?? Other Block Questions...

[Mustang78]

the block with 68' heads turned out to be an 85..casting number E5AE on the side, thats 85 right? anyway the whole previous rebuilder didnt do a good job, is there a VIN number on this bare block that will give away the secret if its a 85 roller or flat tappet block? also i planned on buying a "performance" rebuild kit from northern auto parts ( northernautoparts.com ), but it is for 68-82 ONLY, this 85 block has the one piece rear mail seal also. Is it ok for me to buy the 68-82 rebuild kit for my 85? i dont have a problem buying a new rear main seal (i want a teflon one anyway), Thanks for all the help, sometimes there are too many choices and no one seems to carry a performance rebuild kit for the 85 block(i'd like better than stock oil pump, bearings, etc...and flattop hyperutectic pistons), Thanks and if there is a budget 331 stroker out there i'd definately be interested, or a better rebuild kit, i plan to spend around 500 on engine internals, i already have rebuilt GT40 Heads

I don't think the 85 are roller blocks. One way of finding out is in the oil valy under the intake. There should be 2 spots to mount the spyder hold down for the roller lifters. If you don't have that then it's not a roller.

ok, i think it has them..also it has the XXX pattern int he valley

The t-5 carbed cars were roller. The AOD CFI cars were flat. I have owned both over the years.

however, the big question is, were the cfi blocks setup for roller or not?

85 CFI was the same block as the 84's.

i have no idea what car this came out of..my only guess would be the 86GT it was yanked from, but i highly doubt it was original to that car..and im leaning towards it being a flat tappet

Pull out one of the lifters.
