I've been planning on getting 36lb injectors for my 422 buildup. I don't see many of them for sale but it seems that 38lb's are fairly common. What are the downsides(or upsides) to using a bigger injector. I think I read where colonel ran 50lbers on his 422.

 

Brad, you can run them with no problem. You need custom programming or LS1 edit to compensate for them though. I think you can vary 2# either way with stock programming so by going to 38's you will need it calibrated. Hope this helps.
