Injector upgrade?
I have a 98 with 243 heads, whiplash cam, and all of the supporting mods. I think I have a bad injector. What should I upgrade to? There is a chance a supercharger is in my future. What size is stock for a 98?

For that cam (same on that I have) 42's work great. If you go with a supercharger,,,then you probably will need 60's. I dont think that 60's will be any good for just the cam that that you have now.

BCarp,
I'm running the same cam and picked up the 30lb SVO's at the below link they flow higher on the LS1 pressure. I probably should have went with the 42's but you live and learn, my 30's are at 87% duty cycle at 7k rpms so i'm good for now.

I have a set of 42 lb. and 60 lb. that are just sitting around as I am now using 80s Let me know if you are interested..I have been told that at WOT you should be seeing a duty cycle of 80 % so keep that in mind with any comments that should arise. Only what Ive been told by the experts. Cheers
