It will be good for one, maybe two cycles of the brake before needing to "recharge". You will have a false sense of confidence until you have to negotiate a couple quick turns and run out of brakes. Not the same as street driving and stopping at a light with a big cam. Higher idle rpm and initial timing would help more than a canister.

For AutoX your carb will need a few mods to perform well. I tried to get a nice Proform 750 carb to work with road racing and AutoX for a year and finally just switched to fuel injection.
Thanx for the heads up bro...the canister idea is now out. Im sure ill have to do a good bit of tweaking around with the carb to get it to run right on the autox this summer. But since i only do that 2 or 3 times a year its not that big a deal to me.

Pn 30121101 from lunati with face oiling lifters or grooved lifter bores.
Thanx for the advise on not reusing the lifters; you might just have saved my motor from destruction.

Well from what i can see the cam you suggested and the one Vinnie suggested are about the same and gives me a good idea as to what im looking for.

The car is going to be 80% street and 20% autocross. Very little if any strip. That said i want to be a very aggressive street car. I thinkim going to go ahead and order the howards cam you suggested but stay with my air gap intake for now. Maybe i can trade one of my duel plane airgaps for a single plane at some point in the future and see what the difference is.
