Engine is shot - Built 3.5 or V8 Swap

[Hal993]

I say "GT" build. I would say coyote build - as they are the most common V8 swap, but... none of those builds will be more reliable (in practice) or require less attention per mile than a built 3.5.

I have a weird fascination with the 3.5 being a GT derivative. Money no option I'd try to build it as close to GT spec as I could.

It would be too fragile. Couldn't handle the weight if the rig.

Put a Coyote. My buddy did the swap. His Gen 2 is a BEAST!

I think the path of least resistance is going to be the RMB long block, big hair dryers, etc. You will not have as much drama making this work with the truck as stuffing a completely different powertrain in it.

Would a built 7.3 work? Sure, but at what cost as opposed to the built 3.5tt.

If you were rocking a Jen Juan, 7.3 all day long. Twice on Sundays.

I’ve been toying with the v8 swap but I hear none of them make it out without having issues.

Yep, 3.5 BUILT engine is path of least resistance.

Even if you 4.1 or 4.2 it still just engine tuning to get it to live with the rest of the electronics/truck.

Otherwise you are building something that has no OEM electronic foundation, having went down that road with a vehicle once, I am out.

GEN 2 - COBB Accessport - Tuned by GooseTuned

So, unmarried accessport verified by COBB (ECU AND TCM V3) but how do I know if a previous owner put a tune on the truck and never removed it? Saw caution about only overwriting a stock or other COBB tune. Can the accessport first load a stock tune? Need this sorted before I begin a real 91...

Not necessarily, 3.5 is plenty stout enough to handle big power and the weight of the truck. Point taken though, getting it to be as free revving and the drivability of it would be a challenge.

RMB 4.2 all day every day. No electronics to deal with. Install and tune. 750 WHP without even trying. 1000whp with minimal effort.

I have RMB forged 3.5, Garretts, other accessories, and @GooseTuned E85. I haven't been on a dyno but my bish jams.
Would I have liked the sound of a v8... yes but no complaints on my current setup now that she is dialed in.
