Hello Ken, either one of the two part numbers you stated will work. The two part numbers are:

30-113010 is the IPU ECU. This setup would require you to install a crank trigger. One benefit from this type setup would be that the Opti-crap is eliminated. One drawback to this system is that it requires alot more work/install to get it setup.

30-116010 is the LT1/LT4 ECU. This setup is a "plug & play" for the LT1/LT4. One benefit from this setup is of course the ease of installation. One drawback is that you still have to Opti to contend with.

IMHO i would go with the 30-116010. We have alot of LT1/LT4 guy's running this setup, and it works great for the application.

I have talked to 1 customer that used the 30-116010, and he had alot of problems with the system......after working with him a few weeks, it turned out his Opti-spark was bad! So he ditched the 30-116010 and went with the 30-113010. He swore to never have to deal with the Opti-crap again!! LOL...

So with having said that ,basically the choice is up to you. Whichever you would feel most comfortable running/installing would be the determining factor. The LT1/LT4 ECU is setup for your ignition right out of the box, the IPU is a more "one size fits all" type of setup. Either way i dont think you would be dissapointed......I would highly recommend you work with a distributor for the install/tuning though. They can provide alot of help on the install and tuning to get the car up and running in the shortest amount of time! Hope this helps......Kevin

 

Thanks for the great info Kevin!
