THOUGHTS?

 

Looking Good, 500bux looks like a steal. I'm in the process of doing a 6.0 or an LS1 swap. Good luck on the build....

 

thanks man I would love to do what ur doing but jus to much money

 

Great deal, car looks to be in awesome shape!

Thats some real engine damage, I'de be pretty mad if that happened in my motor.

 

I have a feeling the previous owner was being a real crazy man when that happen

 

Good job so far!

But holy **** that motor was wrecked wtf happened to it?

 

valve went through the piston with exreme force, im guessing he was probably reving the **** out of it and the valve said "i quit"

 

So Matt, what are you replacing it with? Stock used? Crate? Details!

 

I am replacing it with a used 350 5.7 out of a 91 gmc truck but I am using all of the TPI components off of the camaro. The engine has some miles on it but got it for 350 bucks so it was a good deal and couldnt pass it up, my only other choice was a 454 but I need to pass smog and am saving the 454 for my 69 camaro.

 

did you think to put the Camaro cam and stuff into the truck block? You should (have). Also, those truck heads flow nowhere near what the Camaro's originals did, so be on the lookout for a mate to the one that didn't drop a valve.

 

truck cam should have more low end torque and Im looking into alluminum heads if they have em for these, plus im not looking to haul *** jus guna be a cruiser

 

looks like a steal.... Yea he was floating some valves lol but hell you got a good deal beacuse he was stupid

 

yup

 

can I pass smog with a 160 degree thermostat?

 

Maybe, but you'd have a better chance with a stock thermostat, so why put in one that will keep the engine too cool?

 

was jus wondering since i already bought the 160 one i will buy a 185 one for the smog, I was looking at a chip for the car that said it required a 160 degree thermostat

 

Nice work in progress there. Glad to see you are adding detailed pics of before, during and after this install. The pic below post #3 show attention to detail. These pics also motivate me to go outside and tackle the intake manifold/ fuel rail assembly again. Thank you !

 

Thanks alot man


Well today we got alot done and the engine is now mounted in the car

love driving with those t-tops off

 

love drivin it but im ready for an LSX swap haha

 

You can't imagine the difference.

 

oh i can imagine the difference this is my buddies 3rd gen- http://www.streetfire.net/video/89ls...ey_2091961.htm

 

The next saga in this build thread is suspension, ordering some sportline eibachs for the Z should look good.

 

What a deal! For around $1000 total you have a car you could sell for about $3500. I'm sure you would rather enjoy it than sell it though. I also replaced my L98 with a truck engine and I didn't really notice a difference in power. The only way to really know is to race one with the original engine in it. Either way it's getting you down the road and puts another 3rd gen back on the streets Good job!

 

thanks man, its having an idling issue as of tuesday night surging and smelling like its running lean, its either the MAF or I could have possibly got some bad gas because before the gas station it was running fine, I filled up got about 2 miles down the road and the service engine light comes on mmmhhh. It is only at idle speeds as well when driving under power its totally normal. Any ideas?

 

Do the paperclip trick and get the codes, that will start you down the right road. Might just be the idle air controller from what you described. When you insert the key do you go to key on (engine off) and wait a couple seconds? If not give that a try, my Fiero throws a code for the IAC and when I twist past key on without waiting it'll run like crap. Aside from the codes check for vacuum leaks and put some octane booster in it, maybe it is just the gas. Let us know what the codes are, the're the biggest hint to whats wrong.

 

thanks, my buddies coming over to help me out this weekend on it I will keep yall updated.

 

yeah I do that wait for the fans to kick on then start it up

 

took a lil video of what its doing
http://www.streetfire.net/video/issues_2277524.htm

 

we scanned it and it is the MAF when we unplugged it the car ran fine then plug it in and it started that rough idle again, so I am pickin one up soon and puttin it in.

 

put the new MAF on and it runs great now, thanks sean for helping me detect it.
