    If I put a stroker kit in my 454 will it run without a tune?

    It's a 98 vortec. I might try to find one of the supercharger kits for it too. Depends how much power it makes with all the upgrades.

    I'd rather have the reliability of fuel injection for off roading. this will be a mud truck.

    If I put a stroker kit in my 454 will it run without a tune?

    Let me reiterate I do not intend to drive the truck on the road without a tune. I just want to see if it starts after getting everything back together, then I can tow it to a shop. Not sure how easy it would be to tune a truck that doesn't run...

    If I put a stroker kit in my 454 will it run without a tune?

    Thanks for the help guys. The cam is the only one available from Comp Cams for the computer controlled fuel injected 454. I can pull up specs if you really want to see. Shouldn't be too aggressive. I bought all new bosch fuel injectors from ebay quite a while ago, so it'll suck if I have to...

    If I put a stroker kit in my 454 will it run without a tune?

    The intention is not to drive it without a tune, I merely need to know if it will start and stay running well enough to know it works. If I can drive it to a tuner then all the merrier. I could go straight to a 411 pcm and coil near plug, but that seems like too many changes at once to be able...

    Reviving this question because I'm getting closer to rebuilding the engine. I have almost everything needed except the bottom end. I've asked a few manufacturers and no one seems to know.

    If I put a stroker kit in my 454 will it run without a tune?

    I'm getting started on rebuilding my 454 Vortec and really want to put a stroker kit in it. Do any of you know if it will start and run without a computer tune? I'm also putting a comp cams complete valvetrain kit in it which is compatible with the computer.

    Want to build a 496 Stroker, looking for guidance

    I appreciate the suggestions but I really want to stick with what I have and build something unique. The parts to do what I want are readily available and not prohibitively expensive.

    MSD 6AL....will it work on 1999 k2500 5.7 Vortec

    I put a 6A on my 4.3l Vortec Blazer. It's the older CPI Vortec. It didn't make any difference off the line, but there was a very noticeable improvement in the top end. It should easily connect up to the 5.7. There was an adapter harness I used which didn't require any splicing or cutting of...

    Want to build a 496 Stroker, looking for guidance

    I am slowly getting this project off the ground. I finished pulling the motor yesterday, now I just have to get some parts ordered and take it to a machine shop. During the pull I discovered all three motor mount to block bolts on the passenger side were broken. The engine was just resting on...

    Want to build a 496 Stroker, looking for guidance

    I'm still thinking I want to stroke the 454. I also learned it's pretty easy to convert to a coil near plug setup, so I want to do that also. Comp cams recommended a different cam kit that costs around a grand, so I'm estimating the project will cost around $5000 and produce pretty close to 600...

    Want to build a 496 Stroker, looking for guidance

    I've looked a few times for crate motors, but I haven't found any geared for what I want. The prices are also more than I want to spend. I can get the stroker kit for around $1500, cam kit for $400, and all that's left is block machining and a tune.

    Want to build a 496 Stroker, looking for guidance

    If you've been following my top end rebuild thread you know the 454 in my K3500 is ruined from neglect. I've been thinking about what I'm gonna do about it, and I think stroking it is the answer. The truck is gonna be a mud bogger, so I need as much torque as I can get. I've already got the...

    Oill pressure wiring diagram (1998 k2500 5.7L)

    I should be able to get this for you. I have the shop manuals for a 98

    Engine died doing 70

    Sounds like a bad coolant sensor to me.
