Well i was driving on the Freeway in my camaro doing at the most 90 here and there but then i get of and about two miles later my eninge starts to knock its a 350 the car also ddnt start up after i shut it off i had to get a jump to start anyone know what might of happend and should i fix the motor
or buy a new ... plus where is the best place to get good motors?

 

well, how about giving us a bit more details? What kind of a 350 is it? From factory? aftermarket? tpi, tbi, carb? What year car? If efi, any codes being thrown?....

 

i bought the car in the summer from what i was told it was a 5.7 electric fuel injection i think stock but im not sure i have a few pic of it idk if they help

 

ok. 350's never came in TBI format in 3rd gens, so its probably from another car or aftermarket, (which I'm guessing since the block is blue, another thing that never occurred from the factory). Probably what they did is get a 350 block and keep the tbi stuff from the original 305. What is the engine doing now? Does it turn on only when jump started? or does it not run at all or crank?

 

it starts up fine wit a few pumps of the gas like normal . the engine is making a knocking sound . it still drives

 

is this feul injected?

 

Yes, thats TBI (Throttle body injection). Really hope that isn't a 305 hiding in there. Anyways, is it knocking under load or just while idling? If it's knocking while idling, it may be time to dismantle it and rebuild.

 

while idling but more wen in gear

 

sounds like its time to take it apart and rebuild it...
try not to run it since is could be a spun bearing you can still save the crank.. i would pull it apart and see what its insides look like and make sure its a 350 before you rebuild.

 

around what part of the engine is the knocking coming from? top (intake), bottom (block), or sides (heads)...?

 

yep, looks like a 305 to me you really should replace or rebiuld if you can.
i have a fully forged 383 stroker kit for sale, cheap! if your gonna do it, might as well do it right!!!!

 

like hcr13 said. where exectly is the noise coming from. heck man even a broken or cracked flywheel will make a knocking noise.

 

Flexplate? Check?

 

I thought I had a knocking coming form my car once. Knocked on idle, sped up as I gave it gas and everything. I thought I was screwed, took the car off the road and everything.

Turned out to be the plastic torque converter cover that had come loose and was hitting the torque converter and flexplate lol

 

what would i need to put this motor in mine?http://detroit.craigslist.org/mcb/cto/1558337024.html

 

A carb setup or a good bit of tuning. That will not play nicely with TBI

Id suggest a different motor. How you build a 383 with a stock 350 crank is beyond me

 

I have a stroked 385 that possibly for sale.its a 350 bored 40 over with a skat crank,dart heads roller rockers,keith black pistons,victor jr intake and everything else you want in a engine that makes 475 horses.please serious inquires only

this one sound any good?

 

0.060"-over 400 block.
