Swapping '95 LT1 into a '94 Z28
 

What do I need to know as far as diffences between the '94 and '95 LT1? I know I'm dealing with a vented optispark now. The connector looks the same but only deeper, so it looks like I'll need a different optispark harness. What other subtle nuances do I need to be aware of to make this swap successful?

TIA

The vented opti will need a fresh air feed from the intake ducting (anywhere between the MAF and the TB) and a vacuum source off the intake manifold.

if you are using the 94 engine harness, all you will need is the vented opti wiring harness ( https://www.casperselectronics.com/M...Category_Code= ) , and the vented opti vac harness

This is the vacuum hose you will need.
