What Injectors to use?
I'm running a stock 502 RamJet that ahs two cylinders running (hot 500.F), so I assume it's got a couple of lean injectors. The other six are running between 230-300.F. I can't find anything that gives me a size. The GM Part Number is 17090919. Can anyone tell me what size these are and what would be a good (reasonably priced) suitable replacement would be. I'm thinking they're about 36's. Would I get a performance benefit from running something a little bigger without making another changes? Much thanks...

Your WOT tune would be off with different injectors.
Do other ram jet engines have similar problems? Maybe its an air distribution issue in the manifold? If you move the injector does the increase in heat follow?

That's a good point...I don't know. I'll have to try that. How bad is 500F the hard parts???

I'd read the plugs. If the suspect two show super-lean, then you might be hurting something. I'd check the others also.
