Camaro or Caprice roller cam stuff into a '87-'95 truck 350?

[scouthead]

I have something posted on pirate also, but basicaly, someone told me (and I've seen in print) that cars (mostly TBI 305s) got roller cams years before the trucks, but that the blocks on '87-'95 TBI would have been cast the same, just never setup with the same hardware...

I'm pretty sure at least one of my 2 bolt main 350s ('89 suburban) has four holes drilled in the casting, above the cam... is that how and where the alignment tray mount on a 305? Is the roller cam in a 305 going to be the same as an LT1 (different grind of course)?, or a totaly different animal? I understand that roller cams need some additional hardware to keep them properly located, but doesn't seem like a big deal. I will need to build a replacement for the motor in my '88 K5 that just floated a valve/s, and OEM style equipment is MUCH cheaper than retrofit roller cam stuff (mainly the lifters), so it would be awesome if my poor old TBI motors could except some bitchin new stuff...

I don't have any experience with LT1s or other stock roller setups, so anybody with info, please chime in.

You can pull the intake, look in the valey and if it is a roller cam ready block, you will see 4 pedestal looking things. These hold the spiders that hold in the factory rollers. Even if they are not drilled and tapped you can do so. The cams themselves are interchangable from 305 to LT4 with minor difference in the dowel on the LT models. Also you will need to use a melonized (sp) distributer gear with the roller cam.

Sorry it is only three pedestals. Here is a pic I just took of my engine for you to get an idea. The three bolts down the centerline are the pedestal bolts.

Yes you can put in a roller cam in your 89. Everything on your block is set up for a roller cam. All you need is the guide plates, lifters, push rods ect. It is a bolt in.
The 350 ram jet cams work good real with TBI. If you go roller cam you will good chip tune.
