i blew my head gasket and putting a used 305tbi motor in my trans am, which was a 305tbi. the only motors at most of the junkyards have came out of chevy caprices, vans, and trucks. i just want to know what mods or changes do i need to do, in order to get the motor to work correctly if anyone can help?

 

If you are swapping a 305 for a 305, wouldn't it be easier to just change the Head Gasket?

 

yeah but i ws told that i was gone have to get my heads checked for cracks at a machine shop and plus laborwise it was going be more expensive. and i can get a used motor for cheaper with installation.

 

As long as you didn't run the car for an extended period of time while over-heating, you shouldn't have a problem. I don't believe your motor had aluminum heads, but I could be wrong. Someone correct me if so.

You can basically visually inspect it for cracks, I've blown plenty of head gaskets, checked for cracks, put it back together and ran fine. You need to worry about warping more than cracking, and even still it's unlikely unless you ran the engine while it was over-heating.

 

i cut back since then on driving it. i just need know whats the best way to go. i was just told by a couple shops that i'm gone have to send my heads to a machine shop for cracks and warping which i forgot to mention.

i just know that the labor was gone get in my pockets

 

If your head gasket is blown, you shouldn't be driving it at all... not just cutting back. You're talking long-term damage down the road.

 

Did coolant leak out of the engine, or into the engine?

If it went in and your oil looks like a milkshake, and you've driven it, the life expectancy of your engine has been greatly reduced. So a used engine might be a better idea, but could also be worse.

 

Well I dont know about machine shops in Ohio but having the heads checked and all that stuff would be $50-100 and here if they turn out bad 9 times out of 10 they won't charge you nothing. If you need a 305 pm me I have a 305 tbi in a 92 camaro.

 

get a used 350 from a truck, put a new cam in it and drive it stock will be faster than what you have now. and will still work with the TBI just run your tbi rich and it should make ok power with the 350
