I have a LT1 from a 95 z in my s10 blazer 88. I know, I know I am no camaro but ahhh me and the little blaze try all we can. I am thinking of replacing the Opti on it because the motor has 70,000ish miles on it and figured while I was going in there with a new water pump and harmonic balancer why not replace it to avoid future problems. ITs the factory Opti on it now. What are the best replacement options as far as cost and dependability go? Its my daily driver. No aftermarket ignition system. Stock coil also. I have saw the ones from autozone but they are remans and not sure about a remaned part of that nature.

Thanks for the help.

 

just keep it until it goes out. Some last for a long time especially with a basically stock motor.

 

pretty much stock. Just shortie headers and took egr off.

 

I got 142K miles on mine. Stock internals and just the mods on my sig.

yea, I got 155,000 miles out of mine. Just let it go until it "goes" You usually run into problems when you take it off and mess with it.
