allright i can get a 350 out a my brothers truck for free and replace my 305 wiht it and i was just wondering if its all gonna be worth it or would there be a alot of work for me to really get it running. i guess what im trying to say is there any differnce from a truck engine to a cars (sorry if sound stupid) so im just kinda new to all this but so try not to get to hard on me

 

overall exterior dimentions are the same....

 

Most likely there will be an improvement unless the 350 is worn out. What year 350 is this? Depending on year you may need a new flexplate and do some minor modifications to get the intake manifold to bolt on.

 

its out of a 1991 chevey

 

Fbody891,

What's wrong with your 305? If you're 305 is running good, and not causing you any mechanical problems, swapping in the truck 350 to get some perceived performance gain is probably not going to net a gain equal to the amount of effort you have to put into the project.

In other words... IMPO - If the 305 is running good and you just want to transplant a stock 350 truck engine to gain some cubic inches [IMPO] don't waste your time.

On the other hand... if the 305 is near failure and getting ready to meet it's maker at the JunkYard in the sky..... You're bother's truck engine would be the perfect price and the perfect building block to BUILD UPON to replace a tired or faulty 305. Most guys around here wouldn't spend the time rebuilding a 305 when a 350 would be the same $$.

Sincerely,
Kurt

 

i see what our saying, but yes it is starting to show signs of wear, but with this 350 im not gonna gonna do this right away im gonna wait till the 305 is on the verge of dieing adn throw it in there. but i was also wondering heads could use for it that i can find in the junk yard that i can restore. i can do all of this at school

also do i need to move this to a section?
