OK Guys I decided I am going to build a 350 to replace my old worn out 305. I would like to know what should I be looking for. Truck engine, car engine? Make model year or casting numbers. Basically i am just looking for a 350 motor that will drop right in place of the 305 and hook up to the 86 TPI intake and stuff. Please help I need to do this quick.

At the very least, pull off the heads and oil pan in the junkyard. look for fragged pistons and bottom end. Also try to turn the engine over with a big breaker bar before disassembling it, if it turns over, chances are it is good. as far as the efi stuff, it is my understanding you can put that on any small block, i could be wrong.

i only give the advice about pulling the motor apart because it happened to my when i was young and stupid.

i got an 84 camaro, shes got a 89 mustang. which do i have to work on more?

 

if you just wanna drop it in get a car motor

if you are willing to do a cam swap get a truck or van motor because they are more likely to have 4bolt mains

ya take the pan off if they'll let you and most definately check the compression

as far as I know the EFI should bolt up no prob

If you can't take off the pan or do a compression check pick one from a car that looks stock(no big ram air hood scoops and such), and has clean oil.
you don't want to buy a motor that has been run to death I'm guessing

good luck and have fun
I just did the same hunt and just finished building a 320hp 355 for a total cost of $400 canadian(the fact that I work at a high performance shop does help cut costs)

they changed the center intake screw angle somewhere around 86, also went to one piece rear seal

 

Stay away from four bolt mains. GFM did it wrong. If you want four bolt mains, get a two bolt, and have a machine shop drill it for splayed four bolt mains.

 

look for something with 8-cylinders.
j/k

ask the place. around here they have motors they knew were good and already removed them. I hope you are going to rebuild it right? It is hard to check a block without it being on a stand. At least check the lifter valley and make sure there is no cracks there.
