Just so I got you right, your motor went out and you have another one coming from a buddy, right? Your post was a little confusing.

[87 chevy silverado]

yes thats correct. sorry for the confusion i tor down the 305 mostly by my self with help of another buddy and pulled the block and bottom end with my dad.

[nbpro]

good

[87 chevy silverado]

yea the 350 is carb so i have to change intakes and all new gaskets, get a flywheel, oil pump scence were going to be right there and change the oil filter adapter cuz my radiator don have a oil cooler spot for it. and i may swap my cam and lifters

[spudz]

cool, just be sure to use a mild cam . because your tbi will NOT like it haha. How bad was the 305? you can use your intake from your old motor on the new one.. I think you will want to get injectors for a 350 and a ecm or atleast the prom from a 350 ecm so it will run at its best.

[87 chevy silverado]

and i going to try to repaint the hole engine bay and put in the passenger inner finder(new one)

[87 chevy silverado]

no i have a 2 year old rv cam in the 305 now that we put it in when we rebuilt it. all the bearings and rings are shot. lifters seem to be great so i still deciding if i want to swap what yall think?

RJ, you can use the factory TBI from the 305 on the 350 without a chip change...you should be able to install the whole TBI top end including the heads on the 350...just fyi

[87 chevy silverado]

[87 chevy silverado]

i know for a fact...that the injectors, knock sensor, and chip is different for 350s and 305 trucks.. whether you can run the 305 stuff on a 350 without it running lean or rich I dunno..... tbi is the same an all tho.

im not sure what ur say in the last part.

Was years ago a used to be friend of mine replaced the rod knocking 305 to 350 and no other changes. It ran fine in the low end but if you kicked it when it got to 4000 RPM it fell flat on it`s face and went into a bog. We did a plug chop and found it was going dead lean. He later swapped the injectors over and this helped a great deal but it didn`t entirely cure it. Next came a 350 ECM and a knock sensor and that cured it. I`m not saying knock sensors can`t be interchanged but it was my understanding they work off frequencey and if that`s the case there is different frequencey`s created by different bore sizes. With the 350`s bore being considerably larger and since knock sensors are cheap, I`d swap it.

yea i was clogged up bad supposedly. the iac was stuck all the way open and cousin my weird ideals at times. and wile we are the were going to pick up what we need to make the 350 run its best

[spudz]

yeah the pcv port is usually always clogged up too. easy fix tho. get you a tbi rebuild kit and go through it. Not too hard.

[87 chevy silverado]

well i need to git somethings any way so im not going to argue with a trip to p-a-p
