    How does this sound for a good combination?

    TA Stage 1/Stage 2/Bulldog Heads
    TA S.P.1 Intake
    TA 296-06H Cam Kit
    Roller Rockers
    TA 1 7/8"/2" Headers
    Tweaked Q-Jet
    10:1-10.25:1 Compression Ratio
    3000-3200 Stall Converter
    3" TA/Torque Tech Exhaust
    3.42-4.00 Gear Ratio
    Beefed Up TH-400

    I'm not saying this is what I will end up with, I'm just trying to get this combination thing right, because it is what makes good power, and it is something I need to learn. Would someone who knows what they are doing please tell me if I got this down good. After looking at www.trishieldperf.com at some of the horsepower outputs of the engines and the sizes of the cams in them, it is a testimony to a good combination. Thanks for everyones help with helping me learn.

    3.42-355 good street strip gears, 373-410 good strip gears suck on the freeway. 3'' exhaust are loud. 3000 stall you will need the 3.73 gears. in my opion cars with 3.90 or lower gears with 3000 + stalls, run great at the track but suck to drive around. i run 373 gears switch pitch 400 with 4000 stall, 2.5 exhaust. its not the best highway car, reves about 3800 at 70, but i dont drive it on the interstate that much, but i can idle around town all day long. its a nice driver and i can just slap my slick on and run low 12's.

    With an SCR of 10.25, your DCR ends up at 7.25, assuming 5 deg advance on the cam. That's too low IMO. You'll either need more SCR, like 11.5 or a cam with either shorter intake duration or that same one with a much earlier IVC (like 100 deg ICL).

    That cam is kind of odd... lots of duration, but on a 115LC? Try the 296-08H or H10. The narrower lobe center will up your DCR and give more overlap for more power.
