Would this 22re require premium/efi upgrades
Just wondering if this engine would require premium or would it still run on regular. Also would it work with stock efi? Thanks

Stock compression ratio for a 22re is 9.0:1. The one for sale is 9.7:1... not a huge jump but noticible for power. The seller doesn't mention the duration of the camshaft, nor the Crane part number, so it's hard to say how much it will affect EFI. I checked Crane's website and they don't list a cam with 425/IN and 440/EX lift but the next larger #70-0012 cam 430/444 has 272/282 duration (intake/exhaust) http://www.cranecams.com/?show=brows...umber=704-0012. They mention it as applicable to 22re and as streetable so... shot in the dark.
engnbldr's 268 cam has 425 lift which is less than crane's on lift and duration and works fine with efi. Various people mention 271 is about the max duration that EFI can work with and sometimes requires an adjustment to the air flow meter to idle right.
If it were me in need of an engine, I'd probably buy it. You can always dial the timing back if you hit detonation from the compression ratio, or if yours does not have the knock sensor. If the cam does cause a problem, you could replace it for the cost of a cam (75-100) and headgasket (you know how much the gasket costs).
