Can someone set me straight 305 to 350
I am going to buy a basic 350 crate maybe a 260hp to replace the original 305 in my 86 silverado shortbox.
I don't ever plan to add any performance mods to the motor I just want a reliable motor for my everyday driver with low end torque and similar economy to the 305. What I need to know is will the exhaust manifolds,ignition,quadrajet and inlet manifold.water pump ,fuel pump all swap over ? I am getting a shop to do the change over here in Australia and when getting quotes they all say different things concerning the the above. Way too lazy to do the change over myself. |

Re: Can someone set me straight 305 to 350
hold on a second. you said your new 350 will have a two piece main. if thats true. then your intake probably wont work, and neither will your valve covers.
the 2 piece main engines are older 85 and older and the one piece is 86 and up. I would not go to a 2 piece rear main unless I had two. Point is make sure your getting the the same generation engine your swaping to make sure all the stuff switches over |

Re: Can someone set me straight 305 to 350
Yes the flex plates are diff from one piece and two piece rear seal, new flex is about $125 or so but before ordering count the teeth on old one. I wouldnt reuse old water pump or distributer though
Can you post a link to the exact engine your thinking if getting? Posted via Mobile Device

Re: Can someone set me straight 305 to 350
http://www.cmp.com.au/crate-engines/...te-engine.html
From what I can understand from reading here and elsewhere The LE9 in my 86 is sort of an odd ball year with one piece rear seal but a mechanical fuel pump. Have looked into getting one shipped from the US but works out the same with shipping. They also have this motor http://www.cmp.com.au/crate-engines/...ylinder-h.html but then I need a electric fuel pump inlet manifold . Maybe I would be better buying a turn key motor from the US and get it shipped by the company that shipped the truck.That would take 6 weeks to get here. Would be in no hurry but the 305 is very tired and wants to quit pretty soon. As I said economy is more important than horse power for me but I suppose if I keep my foot out of the throttle there is no harm in having it? |

Re: Can someone set me straight 305 to 350
yes your engine in your 86 was right in the middle of the transition to newer engine and fuel injection. all of the newer engine should have the provision for mechanical fuel pump. your intake will not fit the vortex heads on the 330hp engine. you should have no problem with the other engines. Why dont you have your engine rebuilt. I would think it would be cheaper anyway?

Re: Can someone set me straight 305 to 350
This is Australia!The most expensive country in the world for everything. To rebuild my 305 here would cost more than a new crate motor and I would prefer the extra torque of a 350.

We actually use them in boats as it eliminates the leak issues in the rear main but the older intake and fuel pump work PN 12568759 $1600.00 in Canada |

Re: Can someone set me straight 305 to 350
when people buy those cheap crate mexican engines locally, most people get them rebuilt no one stands by them, not even those who sell them.
why not get a smashed up vt-vx grab the ls1 outta there, i seen rear end wrecked cars go for 2K with ls1 and 150K on the dial. that would be a mental swap and you have everything you need from the donor car. by the same token aussie 5 litre 304 v8 outta vt low comp for forced induction lots of choices |
