Think i blew the motor in my 97 tahoe....

[Biggwaukegan]

Im pretty sure I blew the vortec motor in my tahoe. Makin a crazy rod like noise. Or lifter noise. Unreal. So what are my options as far as rebuilding or replacing this motor. Honestly if its not too much work Id like something different. Then again If its not too much money Id consider fixing what I got. Help me out here. What motors go in without too much modding? I still have to pass emissions too. thanks

383 Stroker w/vortec heads won't be too much of a challenge and you will be able to keep almost all the parts from your 350. It'd give you a performance gain for sure and would probably be cheaper than sourcing the parts for a 6.0l swap.

Agree with the 383, specifically the HT383E from GMPP. Completely legal swap (well, not in California apparently) and a pretty large boost in performance. Its pretty straight forward, and it is pretty much the same Vortec engine, of course stroked to 383ci with some other performance enhancements giving you 435 lb-ft of torque and 340hp.

GM Performance makes a 383 replacement for the late model 5.7. When mine goes thats what Im going with.

383 ftmfw!

Ummm a rod like noise and a lifter noise are a bit different. If you don't have much mechanical experience you might wanna get it looked at, for all you know it's an exhaust leak.

 

[Biggwaukegan]

its no exhaust leak or anything of the sort. I no a little about cars and can put my ear up to the motor and no somethings not right. Not to mention Ive owned over 20 cars in my life so I do have that too. I got my mechanic coming thru tomorrow to help me figure it out. is that 383 alot of $?

 

[Biggwaukegan]

Heres the deal....Im not spending 4 or 5 grand on a motor. Not at this stage of my life at least. No way. So the bigbad 383 is a no go i guess. U mfs win the lottery or something were you got 5 mf grand for a motor? unreal. ANY LOGICAL SUGGESTIONS WOULD BE GREAT

The HT383E is a high performance direct replacement for the stock L31. Its not exactly cheap, especially if you have a budget. I'm not rich, I can't afford one either, but you asked what is easy and/or different. I mean, if you're looking for the cheapest route possible, then you would probably want to rebuild what you have if you can, especially if you can do it yourself. Or look for a low mileage used L31. Another option is a remanufactured engine; You get a brand new engine essentially, still much cheaper than the HT383E, and in some cases, cheaper than a rebuild (assuming you had your engine rebuilt by a shop)

You can either rebuild it yourself and come out a couple hundred bucks ahead of buying a reman motor, or get a reman motor from someone in your area. I know there are a couple places around here that have the Vortecs for about $1500-$1800...all you have to do is swap over your old parts to the new motor...ie intake and whatnot.

Do a search for "Location rebuilt engines" and sub your city in. I found this in my area on the very first link.


5.7 350 Pickup Roller 1996-2001 R 1195 500

That's $1195 for the long block and $500 core.
