    Mercruiser 454 exhaust manifolds

    can mercruiser exhaust manifolds be used on a regular 454? I’m trying to figure out how to plumb a turbo and came across these. Would they work on a street driven truck?

    Missing/bad engine ground

    so a few a month after I changed my head gaskets I realized I didn’t put the head grounds back on the motor, is there any serious damage that can occur? I’m going to put them back on soon but I’m in the middle of moving and don’t have time right now. Could this also be the cause of the truck...

    Weird deceleration problem

    When on the highway cruising and I let off the gas, after about 5 seconds, the trucks fuel trims and timing goes to zero and my rpms start dropping and speed start dropping fast, almost as if the truck is engine braking.

    Boosted 454, Procharger or turbo?

    I have a 1999 K2500 with a 454 and I wanna boost it. The truck will be mostly a street truck with some strip time. I wanna hit at least 1000 whp minimum. Would a turbo or a Procharger work better? Tre performance sells a kit specifically for my truck, or I could go with a turbo but have to fab...

    4l80e problems

    So the issue just happened this morning. The truck won’t shift out of park. I tore the dash apart because I broke the shift lever bracket and while I was in there I can’t even pull on the cable to get it out of park. If I get underneath the truck I can put it in gears and have it roll but it...

    454 turbo size

    Okay, so I’ve been looking around everywhere for turbo sizing on a 454. I’ve heard as low as a 72mm and as big as a 95mm but nobody talks about what they’re good for. I’m looking for a good midrange single turbo size for a 454 that’ll perform well and not be out of its efficiency range. Anyone...

    Turbo build

    Okay so bare with me here. I have a k2500 with a mpfi 454 and I'm wanting to Turbo it. I've been really obsessed with a sequential setup where there's a small and a bug turbo and the small turbo turns off when the big turbo comes on. The whole engine will be getting rebuilt with forged internals...

    Lowered sas

    I have a 1999 ccsb 2500 4x4 454 that I plan on building up and i want to solid axle swap it but I don't want to lift it, I actually want it to sit lower than stock so I can run some 295/45r18 and not make it look funny.
