    1997 L31 Vortec 5.7, 187K Miles Almost Complete

    Any chance you still have the heater hose retaining bracket next to the alternator?

    Oil Lines

    Not sure if I’m supposed to plug websites or whatever here, but google AN plumbing and go to the first website. You need a 40 inch -6an hose straight on one end to 90 degree swivel on the other end for the lower. And 50 inch -6an hose straight on one end to either 45 or 90 degree swivel on the...

    Is there something better than the OEM TBI carb for my '95

    The TBI, albeit unsexy, is an incredibly reliable fuel injection system. I suspect your issues are elsewhere. Are your plugs, wires all good? Any fouling?Have you triple checked your firing order and wire location? I’d also try an OEM coil, they’re cheap on eBay or Amazon. Those street fire...

    Alternator charging wire up grade

    Depending on configuration, e fans are liable to pull 50 or even more amps on high speed. Your stock alternator is rated to charge at 105 amps, and considerably less than that at idle and into the cruising RPM range. You can see how this would cause a problem. The big 3 would be a start, but you...

    in line 6

    You could do it with an Atlas I6 out of a Trailblazer. Not much different than an LS swap as far as electronics are concerned. Motor mounts would probably need to be custom. I hear they like boost as well, but have never actually dealt with one. I don’t see much benefit, you’ll have less power...

    Oil Lines

    To anyone else whose old lines are leaking (which is all of us if they’ve never been replaced), you can convert them to pre-made braided lines with AN fittings for the same cost of Delco replacements and never have to worry about them again. I wouldn’t recommend even wasting your time with the...

    Crate vortec 350, 390hp question

    I guess it’s a preference thing. The L31 is inherently better down low, but after years of working out of 6.0s, I’ve really grown to appreciate them for what they are. I’ve always been a BBC guy, so I’m all about the down low. But I’ve found that a 6.0 with 4.10s is more than adequate for my...

    Crate vortec 350, 390hp question

    Yes, I agree a 6.0 is going to be a much more expensive starting point because they’re all the craze right now. I was talking about the 4.8/5.3 platform. Sure they definitely like to rev, but he’s coming from a 305. You also took an already rev happy engine and moved the power curve up even more...

    Radiator Upgrade - Recommendations?

    I believe I’ve seen them on rock auto, but that was probably for a half ton. They may not make any for the 3/4 ton.

    Crate vortec 350, 390hp question

    I agree that if you take an L31 sitting in your truck and do cam/heads/intake/real injectors, you’ll come out ahead, especially in a towing application. But for a $3k sbc long block, my point was that at that price point you can invest the same money in an LS based iron block application and...

    Radiator Upgrade - Recommendations?

    Those Liland units are hit or miss. They’re cheaply made, but some have good luck with them. Denso makes great radiators for a fair price. I also have had very good luck with Napa and carquest ones. You can get a nice carquest radiator for 25% off at advance with the coupon code. I run one in my...

    P0507

    That’s definitely no bueno, but it isn’t a huge deal either- provided there is not a milkshake in your crankcase. You can get the steel fel pro gaskets and a BWD updated spider both for under $300 at advance with the 25% coupon code. The BWD is literally the same exact assembly as the...

    Crate vortec 350, 390hp question

    The glaring issue in a 96 is going to be your tuning. 0411 swap is relatively simple and will open up endless possibilities. The other thing to keep in mind is that it will be sitting in front of a 4l60e. If you do go that route, I’d be looking for a big external trans cooler. Dollar for...

    Vortec Reliability after MPFI conversion and intake gaskets

    Both engines are absolute dogs in the grand scheme of things, but I’ve always found the TBI to be painfully gutless. Vortecs (when running properly) are much smoother and do wake up a bit under throttle. Reliability wise, the TBI is much better. Vortecs have the infamous injector issues, leaky...
