This is a new one that should be pretty fun. It's for a Club Cobra member, Darrell Kennedy. He's buying a Unique Cobra and contacted me to build an all-aluminum FE for it.
The build will consist of an aluminum Pond block, some Survival Motorsports CNC heads, a Blue Thunder 1x4 intake, with a hydraulic roller camshaft.
Here are a few pics of the cylinder heads and some flow numbers:

I had asked Barry to flow them before he shipped them to me so we could have some comparative data. We both used SF600 benches and our exhaust numbers were within 3-4 cfm if I remember correctly. The intake numbers were off slightly more, but I did a few things differently with the prep and with the flow bench arrangements.
