Story by Liz Miles
The small-block Chevy has been an immensely popular engine since its 1955 release. While many consider this V8 to be a big, fat iron anchor when compared to today’s imported, all-aluminum inline fours, it was a revolutionary engine for its time.
The original Chevy V…
quiero hacerle un swap a mi pontiac fiero gt 1986 y deseo saber sobre los motores y accesorios que tengan disponibles
Bienvenido a bordo!
Si desea mantener todo GM, un motor 3800 sobrealimentado requeriría algo de trabajo pero encajaría.
Pero tu pregunta es para otro hilo. Este hilo es para hablar sobre diferentes motores GM v8.

sloppy mechanics would argue against avoid the 4800 series.
For the folks who have really done it - how bad is the 1998 LS1 to swap? I see there are kits out there to convert to later PCM for relatively cheap, but it sounds like the remainder of the electrical has other cocnerns too if you were to swap to a later year engine.
I have a 1998 LS1/T56 that would love to swap into something else, and i have access to an LQ9. I would need car accessories regardless.. Would be great to swap the LS1 in, and swap it out for the LQ9 down the road - but hesitant to start if it would require a complete rewire down the road anyway.
Thanks!

Well I don't know - maybe you can swap an LS into a Fiero. In the day they made a kit from V8 Archie to fit an old-school SBC. So why not?

So would Richard Holdener.

The computer can't control a 4L80 and you can't get the forced induction operating systems from HP Tuners. The computer is also not pin-compatible with the '99-up one so you will be either doing a lot of repinning, possibly replacing the shells, if you swap to a newer computer. (I forget if the shells are compatible, pinouts are definitely way different)
If you just want to swap an engine, and don't care about swapping in a 4L80 or using one of the custom OSs available from HPT, go for it.
The engine side is 100% compatible with any other 24x engine, which an LQ9 should be. That is the high comp iron block 6.0 from the Escalades, right? Done that swap with the LQ9 harness and a blue/red computer from something or other, which was a 24x setup. The blue/red computer can be swapped into a (blue/green?) harness by trimming the uniquifier tabs off of the different connector. I *think* they are pin compatible but the O2 sensors needed to be rewired because they grounded the sensors differently. Been a while. But I found all the info online at lt1swap.com when I did it. EXTEMELY good resource, there!
Good article.
Why avoid the 4800? It's an over square design, which means it can rev crazy high. It may not have the torque of it's bigger counterparts, but it seems like a really nice option for a sports car.
What am I missing?

I think the double negative in the statement is saying "don't discount the 4.8L; it's still a good engine."
The sloppy guys don't seem to care what you stuff in. Buy the stankiest unit, boost it, hazers.
Holdener got 1200 Big Bang horsepower out of what they thought was a 5.3, but turned out ot be a 4.8L.

The engines are not bottom end limited, the valvetrain is the main limitation, so unless you want to spend crazy money, it does make sense to just go for the larger engines if possible. The 6 liters rev as high as the 4.8s.
I knew someone who wanted a 9000rpm LS2 and something like 75% of the expense was in keeping the valvetrain together, so he scrapped the idea. IIRC he was looking at $9k just for that.
