    High compression heads on a TBI 454

    Hello, I have put together a build list for my 1993 c2500 with a TBI 454. I figure the abysmal compression ratio could be boosted to make more power and improve economy. The list includes: less wimpy cam, hydraulic roller lifters, Edelbrock high compression heads, Edelbrock TBI intake, injector...

    454 marine engine into a vortex 454 truck?

    Ok, so long story short, can’t find a vortex 454 (96+) straight out of a truck to swap into mine (2000 K2500 454). However, lots of older boats, and marine 454’s. If I can find a Gen 6 marine 454, I believe all I would need to swap over is: front accessories, intake, fueling, exhaust manifolds...

    Gen 6 454 Questions

    Ok, so my 2000 K2500 454 has spun a main and or rod bearing. Don’t have the tools to do a rebuild. Found lots of Gen 5 454 motors for 600-1200 but can’t find any Gen 6 around me. So main question, can I used a G5 engine in place of my G6? What’s the difference between the two? I’ve heard cam’s...

    2000 454 rough idle and acceleration while cold

    I’m stumped and hope someone can help. 2000 454 k2500, hard starting, will crank forever unless you give it some gas and it’ll stumble to start, but once it does it idles at 750-850 rpm (normal?) but seems to have a misfire and you can smell gas out the exhaust. While it’s still cold (100-120 on...

    L29 timing gear

    Does anyone run an adjustable timing set with the stock crank sensor and timing cover? I've read a lot of threads were guys had one and when putting the cover back on it won't spin. I know a double roller is out. I'm sure anything from rock auto would fit, but no adjustable sets I've seen...

    I was driving the 92 k2500 doing a dump run going down hill with a load in the back of bed (no trailer) and the truck did not want to stop when I wanted it to. I plan on doing some towing with this truck (dump trailer and possibly short runs with a compact skid steer). So where should I start...

    Questionable epoxy/weld job

    This is an ALLEGEDLY low-mileage 4-bolt main Gen iv 454. I’ve been told it’s been damaged by a fire, I can’t wether this is what caused to block warp & tear. The bore measures stock and the cross-hatching is intact, the interior also showed little wear coinciding with the low mileage. There is...

    1999 K2500 Suburban 7.4L

My pops lives in NC and I'm in CO, so we met 'half-way' in Omaha, NE to exchange. It was a wild ride heading back home between the heavy winds and sloppy rag joint, but it...
