Re: Another way to skin the cat; the High Torque 292 LS swap
Haha, I always second guess myself when I take a perfectly good running vehicle apart too! Looks killer though, the stance is right on!

Ummm, Yeah, we definitely need a lot more info on that sweet little 68!

Re: Another way to skin the cat; the High Torque 292 LS swap
And a few more of engine mods, like that sweet oil fill tube!

Re: Another way to skin the cat; the High Torque 292 LS swap
I just stumbled across this build, awesome work on the LS!
The throttle body/air cleaner has given me ideas on my next future build. Keep up the great work! |
Re: Another way to skin the cat; the High Torque 292 LS swap
I'm very impressed with the truck, great job.
I have a few questions though. How is the throttle set up? Throttle by wire or cable? I am wanting the same swap but with a manual trans in my '65, since I'm going with a manual trans I won't need any speed sensors Etcettera so I'm thinking of going with a standalone ECU. Is that something you would recommend? I think a standalone ECU would make it a lot easier to wire. |

Re: Gauges
I just stumbled across this build! Awesome build! I have a 69 Stepside Im trying to fix up when I have free time.
I was wondering how you did the lights on your gauges ? Looks like washer and some light socket .. Could you explain a little more on what you are doing ? Thanks!! Allen Quote:

You pretty much nailed what I did. The existing holes in the housing are made for the twist in sockets. You can get pigtails that fit, but they're about $3 each. Sockets like I used are $7 for 10 but they're just a bit to small to fit in the holes. So I used small machine screws to hold down some washers over the existing holes. |

Dayj1, my hero, the smartest guy I know, I have a few questions. This pic looks shorter than your first set up. i want the sbc look. can you explain the reason why? I'm in the middle of this swap, on a 1980 gmc c15. i have a 4.8/4l60e, stock harness, and i have two options, the 4150 throttle body, or the thingy, figamabob, you created. my figamabob is an 1 inch thick, to compensate, for the tall fuel injectors. help me out and explain the madness. thanks in advance, Clark.

There are some other possibilities out there. Search for "194 pigtail" and you'll see sockets with various mounting arrangements. Maybe there is something that will work better. |

I'll probably end up using a taller element in the air cleaner (4" instead of 3") to provide enough room to squeeze a MAF in there like the setup on the '72. However, I do like the look of the shorter air cleaner and might just ditch the MAF and go with a speed density tune. Also, the adapter that goes from the 4150 flange on the intake to the 3 bolt factory 5.3 TB is 1/2" tall in my case. That allows the plug on the TB to just barely clear the fuel rail with factory truck injectors (standard injectors and not taller flex fuel injectors). This would be a non issue if had the foresight to make the adapter in such a way that the TB was turned 90 degrees and the electrical connector pointed toward the rear of the engine. Hindsight is always 20/20 :) The TB that you pictured is by far the easiest way to do this if you can absorb the cost. A cheaper way would be to buy one of the readily available adapters for a GM TBI throttle body to 4150 flange and use a TBI unit with the injector pod removed. It won't flow as much air as the Holley unit, but that shouldn't be an issue with a stock 4.8/5.3/6.0. I hope that helps to answer your questions. |

Re: Another way to skin the cat; the High Torque 292 LS swap
DayJ1, I'm in the process of a similar build. Trying to figure out how to run the pcv system. How did you run yours?

The dirty side went from a vacuum fitting (the brass fitting in the intake just below and behind the carb mounting flange in photo 4) to a PCV valve in the driver's valve cover (photo 5). The PCV valve is the revised "fixed orifice" style for the early trucks and isn't really a valve. I have a vacuum tee fitting on it, because I ran the vacuum line over to the brake booster as well. |
