So I happened across a really nice hydralic roller cam specs are 212*/289* .050" lift, .493/.510"
Timing @.050 Intake Open -1 BTC
Intake Close 33 ABC
Exhaust Open 48 BBC
Exhaust Close -6 ATC

Anyway my question is can I retrofit a roller cam motor in my 1988 302 block with out to much problems. I have heard that they were roller cam "ready". Also curoius how much power I can get with this cam

 

You can put a roller cam in your motor but you also need the complete spider assembly, roller lifters, and matching pushrods, there parts you can source from a junkyard motor. You also have an error in those cam specs, there's no way it has 289 deg duration at 0.050".

 

Yeah your right the actual specs are 212/222 @ .050"

Do I have to do any drilling and taping to bolt the spider assembly in?

 

You may have to, only way to know is pull the intake off and see if the spider pedestals are drilled and tapped.

 

So, I'm not trying to hijack the thread, but I have a question.
I have a '67 289 block. Can you do this roller-cam swap without machining the block? I'm looking into converting to a roller cam, and this would be a very affordable swap.

The 67 289 block doesn't have provision for the 1980s/90s 320 roller setup. You can
put a roller cam in the 67 block but would have to use the componets made by the cam
companies since back in the 1960s which would work on the 67 block.

 

Installing a roller cam in a non-roller block simply requires the use of linkbar roller lifters, there are a couple other solutions as well but this is by far best one.

 

Those are really exspencive though. IIRC i saw them for 450 dollars

 

Yes.. there's no way around it putting a roller cam in an older block is an expensive proposition, and unless the application is a racing class where cam specs are restricted you can get as much power with a flat tappet cam for much less cash layout.
