2x on the 440 lift cam from LCE. I'm running a 260 dur cam and it's fine but it doesn't have the kick the crane cam i was running before. it had a 440/435 split lift and would get ya sideways when it came on the pipe. it also passed smog fine. LCE has a 440 cam that's made for efi. I'd sure try it if i went EFI.
