Machine shop can help you but it will be cheaper to buy a used roller block.. The webbings have to be cut and other things have to be done. it's cheaper to find a $300 block somewhere..

The motor i have already has only about 1500 miles on it so if its that costly to put the roller cam in then i just assume sell the roller cam i have and buy a flat tappet cam.

Yep.. The flat tappets aren't horrible but definitely not my first choice.. My old 88' had a non roller block erosion solid flat tappet cam extensively ported and worked Windsor heads offenhauser port sonic intake with 150 shot.. The car would run in the 10's... So there is still alot of power to gain with the right combo and good tune.

Your gonna be on borrowed time with a flat tappet cam, you might get more time running a oil like valvoline with a lot of zddp. Once you shave a couple lobes down and shavings get around and mess up the piston skirts and rings it will make a cheap cam turn into a high dollar short block

I understand what yall saying. That was why i was asking how much it would take to get that roller cam in there. Just a fresh motor and i dont want it to just sit there and be useless. Think i just may get in touch with a machine shop and see what they charge to get it right for the roller cam. I rather pay more and have more vs paying cheap and getting by a few months

No, all you need is the "spider" to hold the roller lifter tie bars in place and the correct lifters.

Well i already have a roller block too but it needs rebuilt and i have the other thats ready to roll and i figured it would be easier and cheaper to use the one thats fresh.

---------- Post added at 10:11 AM ---------- Previous post was at 09:57 AM ----------

Thanks t.h. Im with u. I dont see where anything else would be different. I have had a couple other folks tell me the same thing but i like getting a few opinions before i jump into it ahead of myself. I have also heard something about the cam base circle being different? Any idea?

---------- Post added at 10:11 AM ---------- Previous post was at 10:11 AM ----------

Thanks for your help also Novi

Re: Hydraulic roller cam in flat tappet block

Just make sure your block is in the year range listed.The older blocks are where you will find additional obstacles to overcome.

That's what I thought he was saying.. It is a pre 1985 block... If it's a 5.0 85 up I believe what TH put up will do it..

Pre-1985:

However, the following must be considered. This conversion requires the use
of a small base circle camshaft which properly positions the taller hydraulic
roller lifters in a non-hydraulic roller block. The block must be modified to
accept stock Ford hydraulic roller lifter retention hardware and the use of an
aluminum bronze distributor gear becomes mandatory. Due to the use of
dissimilar alloys in this area longevity becomes a concern. These types of
applications are special order items and can be ordered through Erson’s
Special Orders Department.
Note: Where they talk about longevity concerns, you may be able to use a roller cam made for the newer model 5.0 and the steel distributor gear made for those cams if the base circle is correct.

Yeah that there is great info. That answers any and all questions. Looks like i got options but i think the best is to freshen up that roller motor i have and give it hell! Lol I'll still have forged bottom end and a good valvetrain sticking with the roller. Again thanks alot for clearing this up!
