KDuniverse | Installing vented Opti in '93 | ||

Can anyone provide me with a write up on how to install the newer style opti in a '93? I need to show this to my mechanic at the bodyshop. I am unclear as to where the vacuum lines connect, about the dowel pin, and whatever else should be taken into consideration when upgrading.
Thank you, |

Correct me if I'm wrong, but the dowel in the end of the cam, drives the newer style opti? What is the length of this dowel?

95-96 length on top 92-94 on the bottom. Yes it does drive the opti. |

Oh I see you are wanting to install the newer style opti. I thought you wanted to vent the older style (which is also possible)
For the opti swap you will need a 95 LT-1 timing cover (ebay $30), Timing cover gakset, 3 new timing cover seals, a 95 opti, the correct cam pin length (I used the Lt-4 hotcam :D), the 95/96 opti wire/harness (very expensive from GM $80), and GM venting lines, lots of RTV, possibly a new oil pan gasket, etc. Oh yea a special Kent moore LT-1 hub puller also. Obviously it is quite a process. I would recommend reading this tech tip from Corvetteforum: http://corvetteforum.com/techtips/vie ... TopicID=231&TopicID=2 It's about electric WP install but it covers most of what you are going to have to do. I've changed over to the newer style opti on my 92 but I did it all during my cam change and basically complete topend/timing rebuild. |

If you haven't already purchased parts for this conversion, consider the DynaSpark instead. It's a direct bolt-on, and is better than any of the OEM Optis from GM. It will save you much labor, etc.
I installed a DynaSpark on my '94 back in 2004, and am very pleased with it. Be well, SJW |

what i've learned from all of this was that along with the cam dowel, the drive pin on the rear of the newer style opti needs to be able to go through the cam gear, and into the end of the cam. This, along with the cam dowel, drives the new opti. So, I'd have to change the cam.

I did this with my older style opti before I changed the cam. I really helped with the opti problems I was having. |
