I picked up a engine from a 1995 ram for my 98. The engine I bought has a holley throttle body on it, but it looks exactly like the stock one except with the holley logo stamped on the top. I looked for the current holleys and they look nothing like mine. Did these trucks ever come with a holley from factory as a part of performance package or anything?

 

That is who makes the stock TB for our trucks.

 

They are not performance anything and, Holley has gone to the pot in recent years. They are one of the worst out there making TBs - fact. Fact is, you order a brand new TB from those guys and you'll end up with one that has issues.

Such issues are:
-holes are not drilled though thus, no vac is felt because it's not a through hole

- Issues with form, fit and function due to casting issues, material issues, dims out of tolerance, holes in the wrong place, linkages that don't work and more.

They charge top dollar based on the name but, you don't get what you pay for.

 

I'm curious, what do you plan to do with that engine? Swapping it for your '98 could be problematical since it is an OBDI engine and your '98 is OBDII.

 

reminds me of a friend i have

he has an 89 XJ, which had the Rennix motor (piece o' ****) it was on its last leg (oil pressure was in the can, he had a quart oil bottle to catch blowby, it made the most god awful noise when it was started, and just ran like ****)

he bought a 94 XJ that was well abused as a mud truck, but the motor ran like a top, now as we all know 94 is OBDI, we swapped out ALL the wiring in the jeep, that sucked, along with a whole ton of other **** (oil pump, water pump, plugs, dissy, all new gaskets and main seals) we also put the tranny and T-Case from the 94 in his 89, now it runs like a bat outta hell, idles nice and smooth too

but swapping the wiring, especially the big main harness that runs through the firewall, was a real bitch, i don't want to go through that again, but i may, if we decide to do the same on his bro's 88 MJ

im happy though, the motor on my Heep screams

 

i think he will be ok if he swaps intake manitfolds..98 no egr beside that,,that about all

 

the pcm is different, runs things differently...if anyone here knows about computers, its like trying to swap a single core for a dual core on the same motherboard (if that makes any sense).

 

It does make sense. There are other practical considerations, as well. In CA when you swap an engine the vehicle still has to meet emissions standards in place at time of the vehicle's original manufacture. Putting a '95 engine in a '98 truck means it will have to meet '98 specs for emissions not just at the tailpipe, but for a visual inspection for emissions devices. Making an OBDI engine meet OBDII standards could be a daunting task in that regard and I believe many other states are the same.

 

i know computer and you can swap single cores fore dual cores. i believe like someone else said that if you swapped intake manifolds you should be ok.

 

On the same motherboard? I don't think so. Chipsets are different. It may work, but you probably wouldn't be getting optimal use of both cores.

As for the manifold, it would take more than just that. The entire harness is different as is the PCM. This is definitely not a plug-and-play engine swap.
