I'd skip the engine oil cooler myself. I don't think the exhaust manifolds are going to work out, either, but I don't have a set here to try. I have a set of CTS-V manifolds that I think might work. The Trailblazer ones didn't work. I think the Novak ones are a Vette driver side and possibly f-body passenger's. I really don't want to run headers on this.
Looks like progress.
When it comes to towing, make sure you upgrade the brakes to match the pulling power. It would be a shame to send that engine back to the wrecking yard.
What about a transmission cooler? I can always add coolers later as needed. Also the headers on here are Novak’s, and they should slide right in.
I am absolutely subbing to this. Awesome job so far. Thank you for sharing
