    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...

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

    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...

    Engine died doing 70

    Sounds like a bad coolant sensor to me.

    Need some advice on a 454 vortec top end rebuild

    It's never had a rebuilt trans. The stock one blew out the front seal and the 2nd came from a donor truck, which has since burned up

    Need some advice on a 454 vortec top end rebuild

    Yea i've already drenched it in WD40. Supposedly it's protective properties still apply after it evaporates. Do you guys have any recommendations for how to get massive torque out of these motors? I figure mud pits are a full throttle event so I need strong mid to high end. Comp cams has a few...

    Need some advice on a 454 vortec top end rebuild

    I fully agree with you guys that credit is bad. As such, I decided to finish pulling the block so the internals don't rust and let it sit for a while. It's the sole reason I'm broke right now. It will be cheaper to finish working on my blazer and will also clear space in my garage. In the...

    Need some advice on a 454 vortec top end rebuild

    I really don't have money, but I have available credit. I'm headed out of town tonight for a week, so I got some time to sort things out. Gonna wait a few weeks to get some cash built up then I can proceed pulling the block and doing it right. I have another engine that I was going to rebuild...

    Need some advice on a 454 vortec top end rebuild

    Well there were a couple more setbacks today. I'm missing one of the cylinder head dowel pins, so I stuck a magnet down the water jacket in the block to see if it fell in there. What I found was chocolate pudding. The previous owner said it had a new radiator, now I know why. It was also...

    Need some advice on a 454 vortec top end rebuild

    I didn't get a chance to look at the cam in detail yet, but the old lifters were not pitted or anything. The wear patterns looked normal. I suspect the intake gasket had been leaking long enough to start affecting the needle bearings in them. I've never cleaned or installed lifters before so...

    Need some advice on a 454 vortec top end rebuild

    That's pretty much the conclusion I came to. I made a mistake buying this truck, but it is what it is and I'm not prepared to walk away from it. The frame and cab are solid, and it's never been off road despite having a 3 inch body lift and oversize tires. It was just never maintained, which...

    Engine died doing 70

    I have had a few different vehicles with similar symptoms to yours. My 1994 Blazer had the same symptoms for two very different reasons. The first was a bad engine wiring harness. Didn't figure that out until someone riding with me accidentally kicked the computer which was dangling out of...

    Need some advice on a 454 vortec top end rebuild

    I recently bought a 98 K3500 with the 454. Overall the truck is in really bad shape but I thought the motor was ok. It just appeared to need a tune up and valve cover gaskets. As it turns out I found coolant mixed with the oil under the driver side valve cover, so I assumed it had a blown...
