340 stock cam

Hello gang! I've got a 71' 340 I want to put a stock cam back in. It had a purple shaft, then I put an xe274h in there and just don't like it. I have less than 500 miles on the xe274h. Anyone know a good (cheap ) source for a stock cam? Thank u all!

any 340 or 360 4 bbl engine has the stock 340 auto cam if you can find a used engine or someone with a good used cam from one.

I once used one out of my brother's 78 Lil' Red Express....
