Seems like a very very mild replacement cam for a stocky EFI 305 / 350

my vet is a 1982 and it's stock.I have been restoring it and this is the only cam i can find that can be used with the crossfire injection.The last owner didn't use the right oil for the flat tappet cam. and it clatters when you first start it.it should be a upgrade and sound mild.

I don't know much about the ECM used with the Crossfire engine...
Can it be custom tuned?
If so, then surely you can select any cam grind you want based on what other mods you do. eg heads, manifold headers etc etc

Have you looked at the Crane CompuCam series??

from what i have read.The chip in the stock ECM can not be reprogramed but you can change it.

crane has closed it's doors from what i have been told and summit cams will not work on computer controled engines.

WOW I had not heard about that. I just googled it up and it looks like it just happened recently too. Thats too bad...
