    Well I messed up the engine in my truck, I think I messed up a rod. It knocks when @ idle and how no power, everyone agree a rod is messed up and the engine is toast?

    I am thinking about getting a GM reman engine from the dealership for $1200. 350 c.i., 350 horses, 340 ft lbs of torque, 12 month, 12k mile warranty.

    While I have all the TBI stuff off, what do you guys think of adding a TBI spacer, yes or no? Why?

    I am also going to add some headers, any recommendations?

    I am going to add an intake too, any suggestions on which one to get? Thanks!

    No spacer, no good for torque.

    Get an Edelbrock TBI intake. I'd even suggest Vortec heads, but I don't know if you want to spend the money.

    I say get Dynomax Jet-Hot coated headers if you can't afford Doug Thorleys. Also get the header dual kit and your favorite mufflers.

    Leave the headers off until the motor's in.

    well that is a pretty sweet motor for that price if you ask me... what crate engine is that?

    I would stay away from the TB spacer... IMO they are a total waste of money and they tend to cause problems w/ the linkage... alot of times you have to kinda modify the brackets they give you to make it work... that motor sounds like it will give you more then enough power. I would recommend a Edelbrock performer intake

    ok, I will scratch the spacer. And check on an Edelbrock intake. Why should I keep the headers off until the engine is in? Easier to get the thing into the engine compartment or what? Also what would be some good things to replace while the engine is out? I'm obviously doing spark plugs and wires, distributor, getting radiator flushed, and I think a new water pump. Anything else? I am not sure on the exact engine, a guy I got my starter from is helping me out. I'll try to find out and post it.
    Also everyone agree by the things I said that the engine is toast? Thanks!

    Carefull, If it does have votec heads you may have a real problem finding a votec manifold for TBI, I did. I changed to carb for now. Full fuely later.

    Yeah, the Vortec heads are $400 =/- from GM.

    Edelbrock makes a Vortec TBI intake that will work just nicely if you like.

    Yes, I put my motor in and I imagine it'd be a PITA if the headers were installed before. I remove them before I removed the motor and installed the new one, then bolted up the headers again. Most people I see do it with the headers on already--I just can't imagine doing it that way.

    Engine install is very simple but time consuming and will take a little longer for the TBI as opposed to the carb setup I have.

    When you install your motor, remove distributer if it is in the rear. Remove all spark plugs. If you change out the oil before you run it remove the oil filter too. This is all stuff that can get in the way or break during your install. Good luck. And certainly put headers on after engine is installed. This is also a perfect time to replace those motor mounts.

    If you have any desire to clean up the firewall or the front of the frame, the time to do it is with the motor out. Probably couldn't hurt to wash and scuff-sand the firewall and rattle-can a coat or two of high-temp paint (not the 1600deg. stuff that cures with heat, just the 300-400deg. stuff) on it for some rust protection. I agree with replacing the motor mounts, and would recommend looking over the frame really close for any cracks or other damage. Easy to do with the motor out...

  10. Yeah, scrap the spacer idea. Just get the crate motor your talking about. If it is already rated at 350 HP and 340 torq, your dont need to do anything else to the motor. Thats plenty. You dont need to get caught up in all this HP hooooplaaahh with a 4x4. You needa good solid reliable evenly balanced HP/torq motor and with 350/340 you are already there.
    1200? Sounds offly cheap for 350/340.

    Dawson,

    Glad to hear you have another option other than a, "For Sale" sign. I agree with the previous posts about things to be done. I am really interested in that $1200. 350 HP, from the dealer, crate engine. I could be way wrong on this, but the price sounds more like a bone stock short block.

  12. Yeah, I thing the 1200 one is for the universal 350 crate motor, which would be stock just like the one that came in it. the 350/340 one I think runs for about 2400.

    The universal 350 crate can be upgraded with a cam, heads, intake, and exhaust to yield plenty of power.

    You guys are right--you don't need a special motor to go 4 wheeling, just enough to push your truck down the road. My truck has a 305 in it, but it's built, so it's got about as much power as a crate 350, if not a little more. It's also got about 5,000 miles on it so it's about brand new.

    if you go with vortec heads, GM also makes a intake for TBI engines that accepts vortec heads. Good luck! Jon
