Ok this is the deal. I have a 88 305 lo3 TBI motor (original) with about 146k. I am thinking it's about time for a Motor swap. I have very limited funds and need to know what type of set-up I should go with. I have a new 350 block with less that 300 miles on it. Its just a block. The crank is not good cuz the #1 rod grounded the journal. This motor came from a 1 ton pick-up. It looks perfectly new. I want to build this motor and install it in my car. SHould I go with the TBI set-up or Carb or what?? I know I need a new crank, but should I replaced that rod with a new one? or all eight. Also the pistons look good, and I think they are aluminum, can't remember. What else would I need for this motor? I know i need a cam, head, and intake, and I would perfer getting all GM perfomance parts. This is for a daily driven car, but would like for the strip as well. WHats ya'll opinion?? What would make this thing kick out some power from GM performance parts??? Thanks

 

I would buy the goodwrench crate 350 and sell the block and other parts. Unless you are willing to spend a lot of time looking for the right deal on inexpensive parts, I think you will end up spending as much money.
ON the other hand, If you get the right deals
you might be able to do it cheaper. As Far as the rod and crank issue go, you will have to have the crank turned assuming it can be, and buy the correct size bearings to match.
Have the rods checked to see if they are ok, but I would probably replace them. It all depends on how much you have to spend and what performance level you hope to achieve.
GMPP are NOT cheap..................bob

I did the 305 to 350 swap, but used a 77 corvette 350 re-cammed instead of the GM crate motor. May have saved about 1000 total, after all expenses. But so far am happy with it. I also dont have smog problems here either.

 

The crank is a gone pecan. I know this and the rod looks good, but Should I keep this a TBI setup?? or what??? I can get gmpp parts
at a real good price I think, working for gm dealership.

 

There have been a number of posts regarding Keeping TBI VS converting to TPI VS Carb. I would check the archives. Personally, I wouldn't convert to TPI just cause I don't have the technical ability or time. For pure performance I think going to a carb is the best and cheapest route assuming no emissions checks. But you can certianly run the TBI and make a change later...........bob
