need help identifing a camshaft out of a rebuilt 85 cfi motor
got a 85 cfi motor to the best of my knowledge, i know its not e7 casting or e6 i think its the cars original motor. pistons read .030 on top tryn to find out what those are to they just have a s inside a sheild looking design and a part number and 2 f's on the other side. as for the cam i think this could be stock or aftermarket. the markings say c or g5 and d5 near the gear then d6 an104 or 04 on the other end and 3 lobes up from the flat end it says 1206 and gwc or cwc on the flat end it says 965360
what is this cam? its out of a rebuilt 85 car non roller. and the lifter holes look the same size as roller ones. how hard is it to convert to roller cam? i have a stock roller cam from a 89gt and the roller lifters and spider and all associated parts. thanks in advance

if its a roller block you just need a roller cam lifters and the spider setup.
if the block is non roller then you have to get a reduced base circle cam and after market lifter(read mucho dinero)

something isnt right here the top cam is out of the 85cfi motor, supposed to be a HO, the bottom is supposed to be out of a 89 tbird HO roller motor, i know it was a roller but can it be a non HO roller cam? arent cams differant for non HO mootors?compare the lobe placement of the 2 in the same clocking there not even close.they arent even made or machined the same. the 89 cam has no markings like the other one the last end pic is from the 85 suspected mystery cam

well the block stamp was e7te and the guy said it was from a 89 tbird. ive seen t birds with steel and aluminum valve covers both i figured the later one was a HO motor.no 5.0 tbird period?it would make sense though when comparing the cams. some lobes do match up sorta.
so are roller lifters about the same size around as flat tapett ones? the holes look large on the 85 block.could it be a roller block casting with out rollers?

all blocks were stamped that from 87-90 irregardless of being roller cam or roller ready blocks, what hade them h.o or not was the firing order on the cam and use of e7 heads and the forged pistons amongst a few other minor details

If you were to see a H.O. motor and a non H.O. motor that was complete in a car the non HO intake faces the driver side while the HO faces the passenger side. The diameter of the lifter holes are the exact same for roller and non-roller blocks. It is the height of those holes is what you need to worry about with using a roller cam in a non roller motor. This is why you have to use a small base circle cam to convert to the usual spider plate/dogbone setup used on H.O. motors or linked lifters with a normal roller cam.
