    would boring an aluminum block be a bad idea? and to be conservative. what are some options I can do for 10k and under?

    just read an article about cam head combos. I really think a livernois stage II cam and trickflows ts3 heads might be the direction I take. those paired with a fast 102 would be plenty of power. thoughts?

    If you feel you're getting more power manually shifting an auto, your shift points need to be re-tuned. Sounds like the computer is shifting the car too early.

    article I was referencing

    Cylinder Head Testing - GM High Tech Performance Magazine

    and I did have a lot of questions about why I stayed in my power band longer when shifting manually as opposed to automatic.

    Wish it listed the cam specs but by my calculations that is a good deal.

    No guessing or chasing parts. Only thing I would swap out of that kit is for ARP hex bolts or studs.

    If I'm looking at it right it does when you click on the kit combo link.

    my current cam is about the same lift. and the intake/exhaust is 238/242 at .50. I'm doing this top end kit with the 102mm fast with the throttle body. what would be a good cai for this size?

    fast toys 104 lid. Its what I have and its awesome. Also if you are looking at aftermarket heads go with the tfs ls3 255 heads you will not be disappointed. I have those on my 421 stroker but at some point I am going to send them to get machined further by FRH for even more power. This paired with a fast 102 and a matched cam and you'll get some good numbers but even more importantly the car will run.

    Comp Cams has a nice on-line cam selection tool you can use.
