i have an ls1 camaro with big cam(228 I/232 E) 600 lift, ported TB, ls6 intake, LT headers, fullly CNC ported 243 heads. I want to change out the stock injectors. what size injectors should I go with?

 

That's actually a relatively small cam nowadays. You should be fine with 36lb injectors assuming you are going to stay with this current setup.

 

I'd go with some 42's personally, so you would have some room to grow if you decided to later on

 

I have stock injectors on a 231/235 .617/.621 cam and i have stock heads as well that have been milled and hand ported and it all works just fine. If you plan on doing more work then yea get bigger injectors if not do'nt worry about it.

 

You may want to go larger on injectors if you change to,say,a fast 90 or larger intake with your combo.One choice i used with great results were the ford svo 30lb injectors with the fast 92,but as for what you have,the stock injectors will be fine.

 

I'd get at least 42lb, there not much more over the 36lb. With my setup and 42lb injectors they are at 80% duty cycle.

And yeah, that's not a big cam at all.

 

Id say 42# assuming there's a good chance you might change your setup in the future, if not than like I said before 36# is good for your current setup.

 

i was at 100% cuty cycle with stockers, went with 36#
