Cam gears Q?? Guys, I'm installing GM's Hot cam on my Car next weekend and I was wondering, should i replace My stock cam gears and Timing chain?
I was thinking of replacing the timing chain with a new one and that about it but a friend told me that i need to change them to after market one's.
so what do i do?

There isn't much in the way of aftermarket alternatives if you keep the stock style waterpump. A new stock set would be a good idea and are pretty strong.
I could be wrong here but I thought the 94-f-body with it's non-vented opti got a different cam nose than the vented opti and the HOT was made for vented? Hopefully someone else can comment on this.

LT4 Timing Chain set is for 95-97 vented opti's. The cam gear is different than 93-94. Non-vented opti's drive from the shaft in the center of the cam. 95-97 vented opt's use the dowl pin from the cam to drive the opti.
Since you have a 94, you will also need to shorten the dowl pin on your hot cam for a non-vented opti style. I would reccommend changing to timing chain set with an oem one since you are there doing the work. If you want to use the LT4 set, you would have to convert to the vented style opti, which requires you the change the timing cover, new opti (vented), search for a write up on it. Check this web site out. Great info on How To. ShoeBox

the shipping rates are really inflated now.
If it were me I wouldn't worry about converting to the vented opti or anything and just get the replacement chain. The gears should be fine. I believe you would be able to tell if they were worn considerably.

Any wear at all on the gears will cause the new chain to wear and match the gears. That why I would relpace them as a match set. just my .02 cents. I would also replace the lifters with a new cam. Since the lift is going to be much higher than they have been working at for the past 12 years and if any are worn, they will mess your new cam up. Again just my .02 cents.
