The LOJ Conversions heater core outlets are used to redirect the factory heater core outlets allowing engines to be placed closer to the firewall. These also change the outlet sizes from the factory 1/2” inlet and outlet to 5/8” and 3/4”, which is the same as the ports on Gen III/IV Small Block Engines. For a complete How-To installation video, please visit the support section of our website.

David S.I was reminded this morning, two years after I bought my Z32 swap kit what a great company this is. LOJ is always there with excellent advice, not just great products. Best customer service of any company I’ve ever dealt with, and the highest quality swap parts available. If you want an easy, bolt in swap, this is it. Click Here to See Review
