? 87 350 fi engine
 

can i take a 87 chevy truck 350 with FI. and pull that intake off and put a 4 bbl. intake on it. will it work

Re: ? 87 350 fi engin
 

Pretty sure it will, I believe you have electric fuel pumps in the tank, not sure if that will interfere somehow.

Re: ? 87 350 fi engin
 

yes you can iv done it. edelbrock make the intake it 209.oo with out the egr setup. here a picture of it on the block. http://home.comcast.net/~furrsam/engine_right.jpg

Re: ? 87 350 fi engin
 

yes you can, but you need a vacuum advance distributor, and you'll have issues with the electric fuel pump (or pumps) that are in the tank because they run higher pressure that a mechanical pump....i just got rid of a truck that the p.o. had done that too....

Hey guys i dont think he talking about doing it to an '87 truck i think he wants to put a '87 engine into an older truck but convert it from FI to a CARB.

If so you can do it but ya may want to change to cam and run something that will match up closer to the carb and intake combo cuz the FI cam is not gonna produce alot of vacuum.

And you can run a electronic distributor as well or any other type you want.

Yes like i did i have a 1989 gmc jimmy motor that was tbi in to my 1986 which was cabarated.

I didnt change the cam and the truck runs great. i change the distributor ofcourse but thats all.

Like i stated before the main thing is the special intake. because of the catty cornered bolt aroung the carb area you need that intake. I got mine from edelbrock and the cost is 209.00.

hope this all helped Also i put v belt on theengine wish i had a serpintine setup.

Not trying to be an @ss, but why would you want to?

Re: ? 87 350 fi engine
 

If you are going to put an aluminum intake on, an earlier intake can be used by slotting the 4 center holes. It would work for an iron intake too, but would take forever to slot the holes.

Re: ? 87 350 fi engine
 

thats right, been there! four middle holes have to be drilled,

i bought a 87 short bed and i am going to use the bed on my 79 bb truck and thought about the 350 in my 79 dd to replace the weak 305 so i need to change cam and intake thanks

Re: ? 87 350 fi engine
 

why would you have to change the cam?

Re: ? 87 350 fi engine
 

change the cam for a little better sound

Re: ? 87 350 fi engine
 

I will agree with gas prices going up after my conversion i wish i still had the stock tbi setup. but i dont and dont really know whats all involved in make a non tbi truck a tbi.

Fuel pump?
The TBI engine won't have a provision for the mechanical pump.

Re: ? 87 350 fi engine
 

Do you still have the parts truck? The whole parts truck? Why not use the wiring harness and the computer and run the TBI? You might be able to use the tank with the internal fuel pump.

I have an 88 with a rotted frame and I'm considering doing the same converson.

Re: ? 87 350 fi engine
 

i got a 79 that i want to put it in and though of doing it that why how hard would that be

Re: ? 87 350 fi engine
 

Actually that would be the best and easiest way to do it!

If you still have the complete donor truck then it's just a matter of removing the complete wiring harnass and engine and fuel lines and tank and installing it all in your '79.

It's alot of work but not that hard.

Plus you have a low maintenance & high reliability of a modern FI system in your truck.

Re: ? 87 350 fi engine
 

Its not even the complete harness as the ECM(PCM?) is on a stand alone harness I THINK.
Where's Russell when you need him...

Re: ? 87 350 fi engine
 

thanks the 87 does have 2 tanks and the 79 only has one could i do it and keep the one tank

Re: ? 87 350 fi engine
 

They are "slightly" integrated for ground and power I think, but it wouldn't be too hard to pull it.

You can run the single tank directly to the TBI and bypass the fuel selector to use just one tank.

Re: ? 87 350 fi engine
 

i took the engine harness off a 90 burban and plugged it in to my 86. i did have to splice into some of the wires. i have dual tanks, and since i did not have the factory dual tank selector harness. i had to run wires from my fuel pumps and use a toggle switch to turn left or right pump on, to switch the tanks i used my factory switch. if you can get it done tbi is a great running set up.

Re: ? 87 350 fi engine
 

thanks i might have to try it

Re: ? 87 350 fi engine
 

No provision = blanking plate in place of.

Re: ? 87 350 fi engine
 

it got a block off plate on it

Re: ? 87 350 fi engine

He asked if it could be done, I was just pointing out that the engine will have no way to run the mechanical pump; you will need to come up with an alternative (electric) fuel pump.
