1995 v8 swap

so hi everybody as you can all tell im new here, my truck is a 1995 s10, 4.3L TBI 4L60E trans, ac and 4x4. so i am planning on doing my swap some time soon. what i have is an engine from a 1994 chevrolet van it is a 350 4 bolt tbi bone stock. so what i know is i will have to do some oil pan work, i plan on cutting mine and adding an extention to it using my stock oil pick up tube from my 4.3. all my stock wiring and everything will all plug right in.

so what i am wanting to know is whare to get a prom that will function correctally with my setup. i plan onm keeping my ac and heat as well and as for my exhaust i am thinking of using the manifolds from the van as the full size truck manifolds will drop the driver side right on top of the frame rail. so any input is apreciated.

Re: 1995 v8 swap

Hey Steve:
What is this prom that you mention?? are you trying to stay away from headers??? And why not just use the van manifolds? do they drop in?? clear shot for the pipes?? What kind of van is it?? will the "pipes from the van hooked up to the manifold" with the crossover and O2 sensors and bolt up under the S??? Can you Do you Weld?? Hummmm.......Lot's of questions LOL!!!

Let me know about the prom and we can talk more on the rest. Most of my build's were done back in the late 70's with LUV trucks and 80's with gen 1's and a few Vegas back in the mid 70's. So I'm full of answers but maybe not for your questions, but I'll try.

Miloh.

Re: 1995 v8 swap

well prom is short for Programable Read Only Memory it is a chip that is inside the ecm that controls fuel delivery and spark control , i am trying to keep my truck EFI (electronic fuel injection), the van that the engine came out of was a 1994 full size chevrolet van, not really trying to stay away headders, i just have theese manifolds and they look as they should fit in with minimal problems, i will how ever have to get a custom pipe bent up for the driver side to connect to the y pipe but pass side should line up realitvly good, yes i do and can weld

I don't know about the ECM having any control over the 4x4, I wouldn't think it matters to the ECM about that. Oh well I have not helped you any at all. I'd start with salvage yards I guess if it were me, most of the part's stores can test the ECM for ya if you find one. A new one will cost more than the truck probably. You might check around the web for the chip. Other than that Sorry I didn't help and Good Luck.

Re: 1995 v8 swap

ya a salvage yard is likely my best bet, but what i am really wanting to know is which ecm will work with my stock wiring and gauges. or if i will have to change the entire ecm or if i can just change out the prom chip

Re: 1995 v8 swap

Where is your PCM on you 95 located? if it is the one that is in the right kick panel then I would advise getting your hands on the OE for the 94. If it is the one on top of the coolant bottle, I really have no answer (other than IMHO ditch the fuel injection, save yourself some major headaches, and make your own custom gauge panel)

Re: 1995 v8 swap

I was referring to the OE for the V8 motor (So long as they both have the red and blue connector).

Just be ready for some headaches and alot of time. The 95 S10 is known as the queer year and it is just going to multiply the electronic challenge.

Re: 1995 v8 swap

ahhh ok i got ya. i have noticed that my truck is diffrent than alot of other 95's ive seen a couple like mine but i have also seen some MPI engines. so if i get an ecm from a truck with a 350 aslong as it has the same plugs it should work? what about my factory gauges? transmission controls? ect...?

Re: 1995 v8 swap

well i think i have got my problem solved, i have received alot of help from brian at www.tbichips.com he has told me all of the info i need to gather for him and he will be able to make me a custom calibrated prom chip to work with my truck. so now i just have to get one more peice of info off the stock prom. then the only thing that will be left is to actually do the swap

Re: 1995 v8 swap

it should bolt up the 4.3 and the 350 are basically the same engine minus 2 cylinders, your front accessories should even bolt on the same im doen a v8 swap on a 95 2wd but havent decided whether or not to keep it tbi. i have heard of guys running the stock ecm and prom and it ran but it always ran lean.

Re: 1995 v8 swap

ya i knew about the 4.3 accesories fitting without problems. i just wanted to make sure that the oil filter bases were the same also . if you check out www.tbichips.com brian can set you up with a custom tuned prom chip to correct the lean issue, he can even do tuning for custom cams, intake ect.. it may be worth you looking up

Re: 1995 v8 swap

i will be keeping my ac and power steering power brakes all of the neat stuff that i can i actually custom built my own engine mounts. they will be using all of the factory mounting holes and they will be keeping the rear of the block in the stock location (trans wont have to move) they were actually pritty simple to make just some plate steel and some reinforcements. dont have any pics of them at the moment could get some if you like thoe, just let me know

Re: 1995 v8 swap

so i have been reading that a bunch of you guys use fans out of a dodge intrepid. so my question is how well dose it fit. lots of mods or basically just bolt in? and the other question is what year of intrepid would be the best. the later model intrepids 98 and on use a fan that is 30.7" wide out side and 15.9 high whare as the earlier ones are 29.3 outside and 15.8 high. so which one should i get?

Re: 1995 v8 swap

been thinking more about my exhaust. i want to know if the "slick fit" headders are actually worth the 250-300$ they look like they will fit well but the price seems to be extreamly hi for what they are

Cool, I read the info on them and saw no mention of S10 v8 anywhere and they don't look to have any clearance provisions bent or built in so I just wondered.
Let us all know how they fit, I'm actually interested to hear how they fit and most importantly how they flow. They look dam good and shiny.

Whay??? MY PIPES!!! LOL!!!! if that's what your talking about I know but that's what was on it when I got it. I need a ...just a little bit to get something done, I'm asking around abt replacements now. But they do work ok other than a little leak. I've even thought about wrapping them to kill two birds so to speak and work on the under hood heat. Anyway thank's for your comment that was very helpful

Re: 1995 v8 swap

well its in, its running, its driving. tad bit slugish (probably due to the 4.3 computer) but it has a nasty oil leak on the pass side someplace. hoping that its just the valve cover. if its not the cover dose anybody have any ideas whare the oil could be comming from on the pass side? dosent look to be the oil pan thankfully. thatll be a task for the week ahead.

Re: 1995 v8 swap

have you thought of mounting the rad in the "forward" position.

BTW, I like your swap. a quick look under your hood and you wouldn't realize its been swapped.

Re: 1995 v8 swap

I use 2 fans, one setup as a pusher, and the other as a puller. On the "puller" side I also have my trans cooler. It is very snug....

Re: 1995 v8 swap

ya i did think about sliding the rad ahead but then i started thinking that seems like alot of work. right now i have a 13.5" pusher fan jammed infront of the condenser its helping for now, i should have a set of 12" pushers sometime next week that i will fit behind the grill and see how thatll do for me hopefully all will be well

Re: 1995 v8 swap

I don't think two 12's wont fit side by side. I believe mine are 10's, and they dont fit side by side.

Re: 1995 v8 swap

2, 12's should fit fine the opening measures 26"x 15" right now i have a 14" jammed in thare (and i mean it is actually holding its self type of jammed) and i still have room for a 10" beside it so i think i should be fine if not well then ill probably have to slide the rad ahead and then put them inside as pullers

Re: 1995 v8 swap

they will probably be more efficient as pullers. I am not of the mindset that "PUSHERS=BAD", like some guys on here, but I do think the more unobstructed air that travels across the radiators fins makes more effective cooling.

I just double checked and mine are 10"'s IDK why they wouldnt work next to each other for me...
