    Holley Sniper and Gas Tank Swap

    ok... This was yesterday.. Bed went back on today.. Found out that 2 of the 8 bed bolts are kinda boxed in by the new gas tank. Gonna take some narrow forearms and some coaxing to get the nuts on those bolts. Still have a small leak on the distribution block for the brakes. Have to tighten the...

    Holley Sniper and Gas Tank Swap

    It started. First fire up when fast and easy (after re-seating the SD card in the brain box). The next two were chuggy on the starter.. Haven't sorted that out yet. Still have to set idle once up to temp, which it got to, but the skies opened and it was time to call it. No fuel leaks to see...

    Holley Sniper and Gas Tank Swap

    I'm thinking the 3-5" fall over a 3' run from stock filler location to the new tank inlet should be enough. Tank has provision for the 1/2"(?) breather hose that went to the stock filler location. Technically I'll be running a big hose and a small one all the way to the stock location if I can...

    Holley Sniper and Gas Tank Swap

    That was a hard decision to make, not replacing the wiring harness. In the end, I essentially said that if the truck had a better body on it (it doesn't), I'd go that route. I've focused on mechanical resilience for now. If the time comes to shine the turd's body and/or replace panels, it'd...

    Holley Sniper and Gas Tank Swap

    That "filler in the wheel well" is an ignorantly brilliant idea and will be hard not to consider if I can't route to the stock placement. Thinking standard hole with a cheap filler cap interface (read: generic) and then a flap of 1/4" rubber floor mat/mud flap to hide it. As of now, my filler...

    Holley Sniper and Gas Tank Swap

    I've got some of the messiest wiring I've ever seen in this thing.. Pulling clean 12v from the battery via a relay is a cheap/easy insurance against the previous 40 years worth of owners and their strangely colored wires.

    That'll make the bump stop search all the more interesting.

    Holley Sniper and Gas Tank Swap

    Yes. Send and return lines for fuel. I unfortunately will need to use a couple of zip ties in addition to the appropriate, insulated fuel line clamps due to limited access around the shock mount area of the inner frame near the headers. I'll survive though. Finished up all but the...

    Holley Sniper and Gas Tank Swap

    I went with the 32 gallon and didn't make any modifications to the existing hitch mount or rear crossmember. Moving/removing the rear crossmember and/or shifting back the hitch mount would alleviate any issue. I'm not even sure the contact is an issue to worry about. The axle should travel...

    Holley Sniper and Gas Tank Swap

    Yup.. just came to the realization yesterday that I need a relay to run the sniper.. So now I'm waiting on that and some fatter wire to come in.. only had 18g.. Also need a new rear-diff cover.. figured since I had the new tank out of the way to paint and run rubber I'd do the rear gear oil...

    Holley Sniper and Gas Tank Swap

    Nice. I'll probably kick myself later for not just doing the hyperspark now. I'm kicking myself now for not getting the blueprint block prepped for fuel injection and just doing this whole thing when I did the motor swap. Hindsight... I can conceive of doing the project in a weekend, but I'm...

    Holley Sniper and Gas Tank Swap

    Aside from the fun of doing this during a Florida summer under a carport, yes. Gave me an excuse to pull my cheap welder out for the first time in a decade. The less fun part is coming though. I hate wiring. Add to that, this thing has been gone through a number of times by different hands and...

    Holley Sniper and Gas Tank Swap

    Ended up replacing all hard fuel lines with PTFE/steel braid from Hot Rod Fuel Hose. Kits were decently priced and the hardware appears to be good quality. Haven't run anything wet through them yet.

    Holley Sniper and Gas Tank Swap

    I'm actually just finishing up getting the new hard brake lines in, temp installed the new braided PTFE fuel lines, and am starting in on the wiring (my least favorite part). The next step is to drop the tank one last time, spray bedliner on most of the underside, and stick some 1/16" rubber...

    Holley Sniper and Gas Tank Swap

    Making some progress. Waiting on some paint to dry on the frame supports that have been moved and some rain to stop so I can get underneath it and drill up through to bolt down the angle steel for the straps. Started looking into the fuel line options and have decided to go with ss hardline and...

    Holley Sniper and Gas Tank Swap

    More information is always appreciated, so thank you. Ended up with the 31gal TBI tank from the blazer which apparently fits in the frame.. I know others have done it, but was still expecting the worst. Holley sniper and their sniper retrofit in-tank pump for the blazer tank are coming.. Still...

    Holley Sniper and Gas Tank Swap

    Thank you. Is the difference in the 87+ tanks just that they're factory EFI tanks or does the 82-91 tanks still work for my needs? I just have a 360hp Blueprint crate, so no extravagant HP needs.

    Holley Sniper and Gas Tank Swap

    Old, dirty saddle tanks are coming out and I'm leaning towards the 31 gallon Blazer tank to go with a Sniper EFI swap. This is also going to coincide with new brake lines Two tank options I'm looking at currently: https://www.classicindustries.com/product/1983/chevrolet/truck/parts/ft5018a.html...

    Metal Treasures in the Oil Pan...

    False alarm. I did check the floats, but then noticed that the hose clamp employed to hold the fuel line inlet had given up on the back side. The front looked tight, but the back was completely broken. It was spraying up onto the underside of the air cleaner giving the appearance of a beautiful...

    Metal Treasures in the Oil Pan...

    Got everything back together. Swapped out the starter for a mini high-torque for it's clock-ability. Took out my fuel pressure gauge as it was the cause of my minor fuel leak. I plugged everything back in and it fired right up. That's when I noticed the water fall of fuel coming out of all...

    What have you done to your square lately??

    Where/what is that? Cab, bulkhead, or somewhere between there and the starter?

    Metal Treasures in the Oil Pan...

    Well thanks for the warm welcome everyone.. The rest of the old motor appeared to have seen its best days already. I picked up a Blueprint crate 350 and a champion 3-row with electric fans. I got everything installed and even managed to get the new motor turned over for break in. That lasted...

    What have you done to your square lately??

    Swapped in a crate motor and a new radiator with electric fans a few weeks ago. I got it to run for 15 minutes of break in. Noticed a loose fuel hose was weeping so I turned it off, fixed the leak along with a cable going to the starter that had melted to a header during this break in. Now the...

    Tampa Area 1983 K10 44/10-bolt combo with some form of "pre-installed" locker in the rear. 350 goodwrench crate motor 700 trans Acquired a stumble that stuck around through a carb swap. Pulled the oil pan and found a dented bolt and a mini freeze plug from the intake manifold(?). Now the top...
