Can anyone tell me anything about the nasty performance two piece timing cover? I e-mailed them, but still no answer. I was wondering how much they charge for theirs and if there are any problems with them. Yes I know there is another sponser on here who has their own but I think they are too expensive,. Can't get a price from Edlebrock yet, they just say it will be out at the beginning of the year.
Thanks
