What one do i need. Here is some info off ls2.com i hope this guy is still around. What do i need vented or not vented

To prevent people having to go over to the other board to find it, provided here is Jason Chromer's phone number in Florida to purchase optisparks for around (edit: $200 for vented and $300 for nonvented) plus shipping:

850-243-8826
any help would be great

also I read that the vented is better than the non could i switch over to the vented if mine takes the non vented
-Mike

 

93 had the non-vented design. It's not easy to switch to a vented design as the vented design runs off a pin in the end of the camshaft which your 93 camshaft doesn't have. Do a Search to get more details.

 

Here is what's required to change over.
