ok i have an 89 rs with a 305 tbi and there is a 88 tbi 350 out of a chevy silverado okk now my question is can i put that in my car and if so how do i do it if i cant what will fit in my car please anyone help thank you

 

The block will be the same everything up top accesiroies etc will be diffrent are i would think they would be. if u wanted too build a 350 from the block that would work. Not positive on the fitment stuff someone will know for sure

 

It is absolutely identical in every way on the outside. It will drop right in and fit with no detectable difference.

Use the WHOLE truck motor; TB, sensors, EVERYTHING. The only thing you'll have to change is the PROM in the computer.

 

I prefer a slightly different approach...

I would do as suggested above and keep the WHOLE truck engine. Then I would take all of the front accessories off of it. The A/C, alternator, power steering, and all that. Then I would use all of the Camaro accessories on the truck engine. That way you know that all of your hoses and wires line up.

Everything is re-useable between the 305 and 350 accessories. Sometimes the alternator and bracket is on the right, sometimes the left, etc...,

If you use your Camaro accessories only, and the entire truck engine, you will be fine.

 

i looked at the engine ok mine is a one belt set up and that one isnt is that still ok ?

 

Well, that's what I meant about accessories.

I think you should take all of the front stuff (accessories like the A/C, alternator and power steering) and run your old 305 parts, including the water pump, on the front. Your truck stuff will probably work but may cause problems later. You will need to use the water pump for your 305 because it turns backwards from the water pumps that use separate belts instead of one, serpentine belt. If you re-use your original accessories, you can buy replacements from the store for your car and not worry whether or not they will fit.

 

what is a prom in the computer

 

PROGRAMMABLE READ ONLY MEMORY chip

It is the replaceable chip inside your computer. It tells the computer specifically what to do while your engine is running.

You really should do a lot of searching before doing this swap so that you get it right.

what else am i going to have to do for engine swap? am i going to need any sencer's, wireing harness, umm is the temp. senc. going to be the sameand the oil press going to be the same umm any help will be nice first time changing a motor like this i changed a motor in my mazda mx6 before but it was with the same for the help motor i got out of another mazda mx6. am i going to need diff motor mounts.

 

I don't know how it can be said any more clearly. Is there any part of that statement that is unclear, that I can help you with?

Accessories, like power steering and AC and such, are part of the car, not part of the motor. Use what came with your car; unbolt them from the existing motor before you pull it, and re-bolt them to the other one.

 

this is my first time doing this so i want to make sure i get everything rite the first time and evrything i have another question i just bought brand new msd wires for my 305 will they fit the 350 and also i bought plugs will they aslo fit ???

 

yes they will. almost everything on a 305 will fit on a 350 except for some internals

 

so is it a pretty easy job to do this engine swap???? like i said im a first timer and i cant wait to do it

 

One man's "easy" is another man's "Mt. Everest".

It's easier than solving world hunger.

 

so has anyone done this before. i cant wait till it goes in i hope its pretty easy to in. it has some cam work done to it already im just not to sure on one thing. now the whole wiring harness thing will i need one or what.

 

Check the TBI forum. Discussed often there.

It's even been linked for you above.
