I have a 93 f150 302 that may have the roller cam in it since some say that ford put roller cams in the late 93 blocks. My question is IF this is a roller engine and I wanted to replace the "block" only what years were the 302 blocks "roller ready". I have hands on a bare 87 truck 302 block # E7TE-CA7(stock bore, and no ridge at top of cyl).
I looked at the block...no pistons/cam/ in it...has cam bearings/crank and caps. What would I be looking for if it is roller ready or has the proper cam bearings exisitng in it.

My 302 has blow by and will need reboring aith .030 over pistons. With the 87 block I would not have to go the over bore route.

Thanks

 

Check the following thread, mainly post # 8

If the block has the bolt holes to bolt down the "spider" (holds the roller lifters), it's a roller block.

Thanks for the info and pic. Well looking at the pic my block is exactly the same as yours including the "XXX". What pistons are in the block? Stock? I'm sure my 93 has dished pistons and if so I might change out to flat tops.

 

don't go by the "XXX" i have an '83 NON roller block that has those markings.

 

I pulled that picture from another website, need to check for the threaded holes...

 

Roller cams started in '92 in the trucks, it was a crappy little cam but that's an easy problem to fix.

When you pull the intake you should see this assembly bolted into the lifter valley. This is my E9TE('89) truck block with a junkyard roller assembly installed in it.

 

Yeah I meant to reply that I did see the threaded holes. The 87 E7TE block I picked up has them "plus" he found the spider assy.
I have been reading up on many archives at the site about the 302 economy upgrades and will be looking at doing the cam improvement along with the mustang lower GT intake. I should be able to use the rollers and push rods in my 93 302. I'm getting the 87 prepped so in the near future when I park the F150 I'll be ready to swap the engines. From my experience with engines (chevy) It is a good bet the 93 302 cylinders are worn from a couple of cyl. having blow by. The $50 87 block I bought has no ridges at top of cyl and measured down cyl looks within tolerance. Not looking for a hot rod truck here, only to provide a little more performance. I bought the 93 truck new and have been ok with the 302/E4OD combo.

I have my 67 SS nova 406 sb and 4 speed for street/strip fun. And will start working on my 57 chevy this year.The truck engine tear down kinda came at a time when I had plans to work on the cars. But at least it has not left me stranded so far. Heck the oil pressure when hot is only 20# and no signs of engine problems/failure yet. BTW the truck looks new!
Thanks for all the replies.

 

my93, good luck with the build, and definitely report back to this thread to let us know how it turns out
