    Anyone customized there skid plate?

    The skid plate will look AWESOME when jumping the truck and getting some air. I will say that I never gave it much thought other than it makes it harder to work on anything underneath. But since you have the time why not do some Upgrades.

    L31R Install And Fired 98 Chevrolet K1500

    Been awhile since I have posted and I thought I would get some feedback on a couple of questions. So the engine is in, fired up and break in done, and have done the required doughnuts on the Highway. Minor upgrades done, empty converters, two and a half in out Flowmaster super 44 mufflers, 4...

    Exhuast pipe routing and headers

    Very good useful information with Links added. I was doing almost the same thing with the O2 censor on my header equipped MCSS back in the mid to later 80s, although computers were much different back then. Thanks kennythewelder!

    98 Chevrolet Throttle Body Plate

    Thanks for the replies. What I was looking at was WOT, that the "lip" is reducing airflow. Now if removing the lip causes a lean condition or was an air deflector at WOT, so that the front four runners in the intake are seeing the same air as the rear four because of the offset of the throttle...

    98 Chevrolet Throttle Body Plate

    Hello, what is the purpose of the air deflector on the front of the throttle bore plate? Anyone know if it can be removed for better, or worse airflow?

    98 Chevrolet Throttle Body Plate

    Hello, I was looking at the front underside of the throttle plate and noticed a flush riveted wide piece of sheet metal on the plate. The other side nothing, what is purpose and should it stay? Thanks

    EGR

    I am going to block off Exhaust manifold port for now until my headers show up, and block off intake manifold hole, leave EGR in place with it plugged in and see what happens. I still have the good exhaust to intake tube in case off off idle pinging. What the heck didn't cost anything so why...

    Starting my Tahoe engine swap.

    Sounds like Fun and my main thought is how long will the B82 converter last and that you may be giving up all the low end grunt if you can get the tires to plant? Just thinking, do you ever tow any trailers?

    98 K1500 Thermostat

    The cooler the air and fuel entering the combustion chamber the more horsepower attained. A Givin. Higher coolant temps, thinner oils, are better for fuel mileage but are actually cooking everything under the hood. Now there is truth in the at speed the air entering is cooler than at idle, but...

    98 K1500 Thermostat

    EGR

    Hmm, well let me ask this df2x4, I blocked stock exhaust manifold with simple brass nat. gas cap on the double male steel fitting. Then plugged intake port towards egr leaving egr in place which at some point will get heat as location close to thermostat. Lean condition by computer at idle will...

    L31R Porting Intake

    Thanks for the information. I keep looking at the exhaust ports on the heads and cant see any big power anyway even with cam, and money put into thin casting heads, larger valves, guide clearance, and porting room. Torque numbers are great for a light duty commuter truck. 400 HP is impressive...

    98 K1500 Thermostat

    What is a good temp for L31R crate engine, egr delete, minor port work on intake, and Hookers. Empty cats, duals out back or under bed, no tail pipes? My "friend" has a very heavy foot. 160?

    EGR

    EGR block off being done, 98K1500 L31R crate engine. Question is the hole in the bottom of intake in the center, can it be blocked off? What to use? Do they make freeze plugs that big? Plumbing, or just leave alone? Thanks

    L31R Porting Intake

    New crate engine, just doing some simple mods since I have to get engine in my commuter truck, 98 K1500. I am doing some simple blending on factory lower intake just for grins since it is already off. Mostly all I can see is to take off either casting lines at runners, a little blending going...

    Thanks a lot, can not wait to get a better Grip on my 98. I think that after some, a lot of learning the ropes from owners who have forged way ahead of the learning curve than I will help me to help understand the new reality that is "modern" automotive technology. I can build carb tech, feel...
