    Haha! Yep, we been together about a decade now. This is her truck, she likes this kind of shit too. She also has a fleet of other vehicles including 2 Trans Ams. If your into cars on this level, ya better have a woman that's also into it. Only way a gearhead can stay married. Her family was into cars too, so she grew up around the shit. We have more than 15 vehicles.

    Never understood people that marry people that want to change them. Just means your incompatible. But I know the power of pussy is strong, after ya get it everyday for years, then ya can focus on other shit, like engines.

    Well I've been married a few years longer...36 years this October to be exact & she has no problem with me buying toys either. For years there was always one or two collectable motorcycles in the rec room. I also have a gun/parts room. I only have 4 vehicles right now & looking for a fifth as a project. I'm building a 30 over 454 right now & want something to put it in. Otherwise it might go in my original reg cab 2wd 1/2ton OBS 6.5 diesel pickup. Enjoy your videos...keep em coming! 👍

    This is the second time around for me. First one didn't go over too well. Incapable as hell. I'm low on cars now. When I lived in the country, id have 25-30 vehicle's at any given time. Used to buy and sell alot. Wished I would have kept alot of them now. Had old GTOs and Trans Ams and many GM bigblock musclecars. Can't afford them now. Every parts car worth $10,000 grand these days. Used to buy G-bodys for $50 to $200 bucks for good body's. Miss them days. I only paid $50 bucks for my 79 Cutlass I have now. Bought it 30 years ago tho, and it had a 260 with a blown head gasket. Had about 30,000 miles on it.

    Second time was the charm! Sounds like you were with cars like I was with motorcycles. I had 15 bikes of my own that I collected & 57 for sale one spring. Had lots of cool hot rods years ago. 69 Mustang Mach 1, 68 Mustang Fastback, 68 Dart GTS 340 4-speed, 71 Corvette 454 4-speed 71 Roadrunner 383, 73 Duster 340 4-speed & I don't know how many fox body Mustangs. Just too mention a few. When I met my wife I had my 71 Vette, my 71 Roadrunner & I was in the middle of restoring my second 79 Bronco...so she knew what she was getting into. I met her through a couple friends, she asked if I would take her for a ride in the Vette...I proposed to her in that car! Went on our Honeymoon in a Lifted 71 Chevy Blazer with a 396. Not sure if it was me or the car but she said yes & almost 36 years later were still together! Just getting back into the car thing now after being into bikes for many many years. I bought a C5 Corvette Convertible LS1 6-speed last summer to replace the motorcycle, she was starting feel uncomfortable on a bike. Now I'm looking for another truck or possibly a G-body of some sort to build another hot rod. Nice shooting the shit with ya! Keep the videos coming! Cheers

    I love your content and watch all your vids . I also have a '92 OBS single cab step side 5.7 TBI 700r4 . I've put 4.10s and a Detroit Locker in the rear along with a built 700r4 and have Vortec heads and a chinese high rise dual plane with Demon 750 vacuum secondary and Comp cam 280 roller cam . Would love to see a test drive the way it is now . Thank you Mister Reluctant .

    Sounds like a cool ride. Pretty good trucks to build. I've built a few into drag trucks back years ago. Had a 90 model short bed with a 454 that ran like hell. Thanks for watching man.

    Looks good man, I used to have a 93 with a Q-jet but I had to mount a tps for the 4L60e. Luckily Holley now makes a carb with a tps which would make this easier for those of you out there with a 93-95 electronically controlled transmission. If I didn't live in such a cold part of the country I would do this to my Yukon.

    Yep, this one's a 92. It's all manual. ECM been deleted. Heat and everything still works fine. Gets cold here too. Fires right up on the coldest days. Really if I didn't tell someone it was done, they wouldn't even notice other than its faster than it was.

    For most carb conversions keeping the factory in tank pump with a good return regulator seems to be the most reliable and usually the easiest way, also helps prevent vapor lock which is a really common problem these days.

    Yep, that was how I done it at first, but the pump went out about a month later. So I just rigged it up old school style with a Mr Gasket Holley style electric pump & regulator. Believe it's a 110gph unit. Still going a few years later. It's pretty dependable.

    If your truck is 2wd, a long tail 350 T literaly bolts right in, Gotta move the crossmember forward a couple inches, even use the same driveshaft and shift linkage. Lose the OD, but not everybody needs it.

    Those trucks are so easy to carb swap because the level of technology in these trucks new there practically an EFI swap, there not very far removed from the 86 and older trucks. My 92 has an old school carbureted sbc and it was effortless, I have a fuel cell in the front of the bed so cigarette but can fly out the slider and land on it to make room for conventional 3" dual exhaust which fuel cell location was "temporary" the ah fuck it I'll just put it here and relocate it in the spring....10+ years later still there..... Does anyone know of a 88-98 factory tank that located in the rear spare tire area of the frame that will fit a 92 long bed? I found one once that's a factory auxiliary for pickup or suburban or something but wasn't sure enough to buy it, I've done research but have never found one that I thought that's it the direct factory bolt in! But It's not a huge deal Im a fab/welder in a well equipped good sized shop and I've built a few big fuel tanks for boats so worst case scenario I'll do a custom tank, I'd really like to get that 12g jaz poly cell out of the bed, it looks like shit ta boot the sun made the top all warped and wavy I finally replaced the aircraft style cap leaked bad I had water in my fuel constantly and when that stupid cap got covered in ice and snow what a nightmare, I replaced it with a 3" tall angled neck with a cap style and way better. Someone should have made a super long runner carb intake for those tbi motors like the old 60s Chryslers because those heads make killer low end TQ, people shit on that head but it does what it was designed to do well but that very effective swirl ramp that makes it run strong down low shrouds and shrinks the port so bad it can't flow upstairs worth a shit so it falls off pretty bad up top but they do run stronger than you would think after looking at the design of that intake runner. GM just figured out to get swirl from the chamber shape vs the port and the mighty vortec was born and it's such a a groundbreaking chamber design EVERYBODY OEM and aftermarket copied it! and it's the technology almost all 2v ohv performance heads are based on today. GMs engineers really were killing it in the late 90s early 2000s with the vortec head which flowed over to the LT1/4, the C5 Corvette, then making automotive history with the LS platform, you can't really kick more ass in 5 year span, what about the coyote? BFD Ford built a V8 using the technology imports have used for decades... GM could have but they chose to take the 2v pushrod configuration to it's full potential and it worked unlike ford who chose to design a small displacement engine that's HUGE with SOHC that didn't perform any better or as good than the old outgoing Windsor but it takes up way more room more expensive to build or modify only trumped in physical size and expense of the gargantuan dohc 4v 4.6L I actually was thinking a cool project would be find a late model Ford superduty pickup with a blown up engine cheap, not hard to find late model truck with blown up engine and swap in a complete engine trans transfer combo from a 88-91 ford 3/4/ or 1 ton truck with an EFI 460, that would be epic. I don't see where it would be that difficult...Maybe I'm wrong? I wish I had the time and resources to try it, maybe some day.

    92 suburban has a center mounted tank in the rear. Could probably be made to work. I drive a 84 C-10 daily, it has a 15 gallon fuel cell in the bed. Been there for years.
