I had the manifold bored out and ran a 2" marine 350 TBI unit on it.
I had an issue with low-backpressure from my exhaust setting a code 32 and driving up the NOx emissions though. I put on an aftermarket valve and used a larger than recomeended restrictor washer...Basically I went larger and larger on the washer until the engine hesitated off-idle, then backed up a size. Fixed it right up. No light. Clean emissions...
