im building a 383 FI engine and while its all apart I want to replace the opti. what on would you recomend? Thanks

 

stock ac delco ! every one will agree with me. Nothing else that beat the quality and price.

 

Chandler motorsports has some good optispark! Alot if people have been using them with great results!

 

wow they have some good deals.

 

forum members have been pushing the chandler optis pretty hard. im going to go the route my self when mine goes.

 

90 dollar for opti ? any one know who made this ? that price is cheap.

 

From what i heard it's from the same company that makes the msd units..I bought the lifetime warranty one for 175.. Good price!

 

I have an AC Delco opti with Chandler Motorsports cap and rotor

 

From what I've read, heard, and researched

Chandler, AC-Delco, or Dynaspark are hands down have had the best results. A lot less info/time trials on the chandler's vs. the bigger brands, however, but they seem to be doing well.
