    Dyno time on Friday. Any guesses on what she'll make. This is definitely not the ideal setup for making the most power but I need to get a tune until i can complete the top end the way I wanted to.

    Anywyas, here's the specs:
    Rebuilt 2001 LQ4 with 317 heads.
    Standard bore ARP everywhere
    Heads milled .020" compression ~ 9.75:1
    Crane 228/232 cam .600/.600 matching .650 dual springs
    LS1 car intake, throttle body, 28lb injectors (for now), Walbro 255 in tank.
    1 5/8 homemade long tube headers ( I know, I'm cheap), full 3" exhaust with Dynomax ultraflow welded mufflers and full tails.
    th350 w/3000 stall, 4.10s

    The dyno is a Mustang 1100se model.

    Yeah it's a bit of a mish mash but the bottom end is built tough and this will mainly be a baseline. I'll add some AFR's and a FAST 90/90 combo with some Dynatech headers when the money tree grows in the back yard.

    I did play with my buddies '10 Camaro SS with a catback and I pulled pretty good on him with my crappy mail order tune and a 6000 rpm rev limit so I'm sure she'll be alot stronger once tuned.

    Exactly my thoughts. Put a better intake and exhaust on it, 400 Rear Hp easily.

    365/380 - Mustang dynos don't stroke egos... like others said, intake and exhaust is killin it...

    The numbers will be lower due to the Mustang dyno and a non-lockup converter but it's gonna have torque out the wazoo. My guess 350hp/420 ft-lbs torque.

    420 rwtq would be nice but I'm not going to hold my breath.

    My 5.7 made 385 ft-lbs at 2200 rpm on a Mustang Dyno. Your intake may hurt it, mine has a LS6 and it's a big number helper.

    My 76 has a 04 GTO LS1 with LS6 heads, LS6 intake, small cam, long tube headers and a 350 turbo without lock-up.
