    IMO, whenever ya do a cam swap, have the car tuned to be safe.

    LOL, Dude don't go cheap on it ditch the stock 241's and get a pair of 243's heads for that thing it will help out for that cam. Injectors should be on your list also (42#) they'll help feed that beast. since your a m6 you won't need a stall but a set of gears may help but you can get by running the stock 3.46's. Also that cam is going to be tricky tuning cuz of the duration.

    God I want to so bad, but heads with the size runners I need/want are like two grand after shipping and I can't budget that in until later this year.
    I have a set of injectors from Superior Performance here in Tampa; installed them last week and the car's running real fat because of it hahaha. It'll level out a bit once the came buttoned up.

    I still need to locate a speed shop that can give a good rate on a dyno tune, but haven't found any yet. A few of the places I sopke with are all booked up until the end of October...
    The car should be streetable for a little while without a tune until I can get it to a tuner (I hope). worried it won't be though.
