How would you make a TBI 454 as analog as possible?

In addition to the old-school truck, make this your home for the low, low price of $380,000.


Check out all the pictures on the MLS listing.


"Built on 11 acres of land, this property is home to a decommissioned Atlas F missile silo complex. The underground complex was designed to withstand a nuclear strike and has water, electricity and a forced sewage system to the ground surface"

I'd buy that for a dollar!

If you have your heart set on it, it's not that hard. I'd start with an older manual trans TBI truck though. I retrofitted my 89 small block truck and it was easy. You'll need an HEI, intake and carb, return style regulator, and some planning. BTW, I'm running a carbed TBI 454 in my 69 Chevelle. These engines don't care how you feed them. I believe there are stand alone trans controllers available, but if you want to build a completely old school mechanical truck, It kind of defeats the purpose.

My 89 has a ZZ4 350, Holley 4BBL, HEI, manual trans, manual windows, bench seat, cable operated heater controls, no AC, and is as basic as it gets. The only thing I did retain was the electric fuel pump. I did the swap a decade ago and never looked back. It starts, runs, and drives better than it did with EFI, no cold cranking, fires right off. Mileage is about the same, crappy.

https://www.summitracing.com/parts/sum-850001-1 - This is the hei that I was going to order. Not sure if the one that you had picked would work/or is better or worse if so.

https://www.summitracing.com/parts/wpp-187-1 - This is the shifter that I was going to use. It says it is for the 4l80e, but they also make them for the 4l60e if you get a 1/2 ton.

https://shop.jakesperformance.com/shop/ols/products/4l80e-manual-control-box - This is what you can install to make your 4l80e manual shift without adding the manual valve body, if you'd like.

Please keep us posted. I think that what you are doing is awesome, and would love to follow along.

Thanks so much and will do if I can get this off the ground soon. Cart updated! That shifter is perfect. I want to stick with a 4L80E and 3/4 ton if at all possible. 4x4 is a must so really only looking at K2500s.
As far as the carb fitting on a holley manifold - you have square and spread bore carb and intakes. If they don't match, maybe you can get an adapter? I really don't know on that one.

Yeah. I'm thinking I may call into Summit support to ask a few questions like that which are up in the air. I'll post back if I can get these answers.

Great and encouraging read, thank you. Starting with a manual Burb would really be ideal but they seem to be unobtanium. Would be interested in a swap on a 4L80E if that's possible.

If you're trying to completely analog your truck, the HEI is a fail. It won't run without that transistorized ignition control module. You'll need either a points distributor or a magneto.

Keep a spare module in a Faraday cage then. ;)

Exactly- another spare ignition control module or two into the cage. The HEI would be a vacuum advance model, not electronic advance, FWIW. Not against a points distributor either, but not wanting to go back in time any farther than necessary.

Now we're starting to really get somewhere! Thank you, guys. Summit cart total plus that manual control module puts my crazy project mods total at about $2600 for the record. Big money but not terrible especially when most of it appears to be DIY wrenchable. And, arguably a legit tune-up of sorts that the candidate truck could probably use or need anyway.

In the past several days I've shifted to the realization that a 1995 is actually the sweet spot. Looks like the small block went to EFI this year but the 454 still has TBI for this one last year. I think. Looking for round air filters and verifying it doesn't say EFI on the Carfax reports I'm looking at to roughly be sure. Someone please confirm if that's correct. Keeps me on the K2500 path as intended anyway if so, but mainly because going from a 1994 to a 1995 gains the upgraded interior and exterior for a tad bit more modernization (still assuming things like most of the dashboard would cease to function worst case scenario, but hey, CD player until then). The 1995s still have the floor shift lever for 4WD. There's a few out there but I haven't called in on them yet. I think it's going to be a waiting game for the right one to come around now. Maybe it'll have a manual. I miss having one of those.

So candidates A and B linked before are out. This one below is out of budget, but just to give you a better flavor of what I'm after... leveled and modest lift, though OE wheels and 33" tires FWIW...
