cam trouble

[96_formula]

i bought a lt4 hot cam kit. or atleast i was told and parts were in correct box for parts. i put the cam in block and the front dowl hole for opti is only drilled out 1/4 inch and my opti will not fit. has anyone had this problem or could give some light would be nice. is it incorret camshaft or wrong year opti. it is a 96 so it is obd2. any help would be great

what are you saying? the cam pin is to short? to big around? to long? try to explain a little better

When you buy a cam for an LT1 it usually has the super-long dowel and also the splined center, that way it is setup for both opti's. The non-vented (93-94) use the splined center so the dowel is too long. You simply take a hammer and gently tap it into the cam a little bit. If you run a vented opti you leave the dowel alone because you need the length. It sounds like you bought the cam used and someone had it in a non-vented opti car. Try to pull it out.

Have it pulled out and replaced with a new dowel pin. Any engine shop should be able to do this. Seek a target length of .650" or so for a vented opti.

It sounds to me like he is trying to put a nonvented opti on an obd2 car

No, it sounds like he has a cam for a non-vented car, and his vented opti rotor will not fit into the hole in the middle.

the it is a vented opti i bought a new lt4 hot cam and replaced it im not sure what the other cam was so i wasnt gonna put in something i didnt know what it was. i think it is for a obd1 car or maby a small block cam. kinda of a shitty deal what but it is better now thanks for the info.
