Another noobs here...got some swap questions...

[Jurmeh]

First off, hello and 'grats on an awesome and informative site. Now for the good stuff...

I have an 84 s-10 with a carb'ed 2.8 that, for whatever reason, decided that it no longer wants to run. In my search for a new motor, I came across a 95 Camaro with the 3.4/auto thats been whacked in the back, but will only cost me the tow bill from the guys place to mine. Score. Ive never done a swap such as this, so I have a few questions before I go ahead and adopt the car:

1: what, if any mods will have to be done to the motor/tranny mounts to get everything bolted in?

2:are there any resources for correctly wiring the computer into the truck? I know jack about wiring, but can follow instructions quite well. I'd rather not do this if I dont have to, which leads me to my next question...

3. From what I gather, the top end from my 2.8 won't bolt onto the 3.4. Are aftermarket carbureted intakes for the 3.4 relatively easy to acquire?

4. If running a carbed 3.4 is possible, where would I look to find a standalone tranny controller? I'm assuming its a 700-r4.

thank you for looking, and I'm sure I'll have more questions in the not so distant future. Feel free to give any pointers as well.

4. If its a 700R4, I'm pretty sure you will not need a tranny controller. Its not until you get to the 4L60E (700R4 = 4L60 for the most part) that you would need a tranny controller. The 700R4 should just be vacuum controlled.

I don't know where your info came from but a Camaro 3.4L will take ALL the 2.8L bolt on parts. You can even use the stock carb if you want. I would suggest cleaning up the stock manifold and removing any casting flash with a die grinder and then installing a weber conversion kit. Obviously the EFI system from the Camaro is nice but it does complicate the swap.

Read through the whole swap guide that bszopi posted and then ask us any additional questions you have. Print the swap guide as well for reference during your swap.

Thanks so much guys. I found the swap guide....have read it 5 times so far. lol. HUGE help. Again, thanks so much. I'm sure some more "nit picky" questions will arise once I've got parts in hand and I can see exactly what's goin on with everything.

After driving 8 years in my 3.4L SFI conversion (1982 S10 longbox) I am so glad that I went with the SFI system. Better fuel economy, more power, no issues to deal with at all. Biggest issue I delt with was a bad wire on the external fuel pump. Its been a Fantastic truck!!! I advise against carb, but its up to you in the end.

I figure the FI setup will be the best way to go....eventually. I'm sortof in a pinch right now. Stuck driving my hotrod until I fix the truck. 6 mpg isn't fun at all. lol. I'm gonna use the carb for the time being until I have time to mess with the harness and get everything ready to put in. Go ahead n rig up a new gas tank, get the harness ready, etc etc, so it'll be as close to a weekend project as I can get it. Can anyone point me to some good refernce material partaining to what circuits I'll need, which ones I can eliminate, etc?

"Camaro flywheels are thicker than S-10 flywheels so you can't use a Camaro flywheel in the 2.8L bell housing because there is no room for the fork. 82 thru 87 truck owners with manual transmissions need to obtain a neutral balance flywheel from an 88-93 2.8L S-10. Or have a machine shop remove the weights and neutral balance the flywheel with a flywheel resurface, this would be as good as buying a new flywheel."

Dense as this may be, is this only for manual trannies, or does it apply to autos as well?

[geoffinbc]

The balance applies to both. The thicker flywheel only applies to manuals.

Your 84 will require a new flywheel or machining of your old one. When you look on the back of your flywheel you will notice a large cast in lump on the back. This needs to be removed by a machine shop and then the entire thing needs to be neutrally balanced.

Welp, I got it in and runing. Everything's great except for the carb. MAN that thing is a dog. I'll be lookin to replace the carb n intake over time.........most likely after i repaint the truck. I ended up using the Camar flexplate with no problems. No vibrations, nothin. Thanks for all the help folks!

Now you get the poor fuel economy and about 15 more BHP then you had previously. I figure about 125 over the stock 110 of the 2.8L and 160 BHP that the stock 3.4L fuel injection produces with the stock cam. You can get the power back to 160+ BHP by simply placing a 4 barrel carb on it with a high rise manifold and add a better cam then stock OR install the fuel injection that came with it. Its about the same cost either way. If you install the 4 bbl carb and cam, expect no better fuel economy then what you are currently getting. If you add the SFI, expect Better fuel economy. Sure, you got it done quick, but its no wheres close to the power it could potentially have.

I have had both SFI and stock carb pickups and there is a Huge difference. We even installed a crate motor 3.4L into a Jeep that had the 2.8L. Hardly an improvement. No power down low or anywhere. From Everything I see, the fuel injection really makes a big difference.

BTW: The automatic is not exactly a speedy thing. It could probably use a bit of tweeking as well.
