Having sold my good 540 I need to freshen up the 522. The 540 was an alcohol engine, the 522 ran on C14. I have spent a lot of money on the alky changeover and would like to use it in the 522. Do I need to change the cam for the switch over? The current cam is .765/.731, 282/292 @ .050", 110 lobe center and is a 7/4 swap. Is there anything else I should be worrying about?

I don't know abou the cam but would think it would be fine..I know Curtis said something about a cam change with big motors with regards to duration..
Do you have a carb or injection??

With that mechaical injection, you'll need to buy LOTS of oil for oil changes you'll need after each race. ;-)

You'll also want to pull that pan 2 or 3 times a season to clean the sludge out of the bottom of the pan.

That cam sounds huge. What will it idle like. Wouldn't you need a vac pump for the brakes to work at idle?

Thanks. I needed a good chuckle. You can see a picture of my car in my avatar. No power brakes but yes it does have a vacuum pump.
