replacing the Optispark with a Vortec Distributor As most of you know the company that had been performing this mod are MIA. so today, I dropped my LT1 intake off at a machine shop to accomplish this mod once again! The operator Is going to build a jig to accomodate the proper location and height of the distributor hole. Of corse we will have to use a mock up motor to get this right "IE My motor" then he will transfer that to the jig for future mods. once this is done, he will be able to turn more intakes out rather rapidly. please let me know if you are interisted in having this done? I do not know the cost yet, mine will be the most expensive I would guess, I get to pay for all of the R&D

I think it's a good idea. While I plan on trying to modify an opti to take the cam sensor from the distributor and run it all up front as originally designed. Then there really is no give away that I'll be running the upgraded PCM...aside from a maf on a 93. lol. Modifying the manifold should not be very hard as it has been done hundreds of times in the past. There was even a guy selling them on ebay that had the hole drilled in the back with a spacer, modified for a traditional sbc head tom intake pattern and two nipples installed for the coolant as well. GL!
