This summer, I am planning on rebuilding my TBI 350. I've been doing some research, and have come across a few rebuild kits online. My question is, is there a difference in any of these kits, or are they all essentially the same? I know that the cams in the TBI trucks are a little finicky, and was just wondering if the rebuild is even worth it or should i try to find a complete running engine. Here's what I have found so far...

I know that with some of these kits, I am going to need more than what they come with- I am trying to do this on a budget, and am just looking for some guidance. Thanks in advance.
 
IMO none of the kits you listed will work on the stock TBI chip. The SDPC kit looks like it is for carbed 350 with 2 piece main seal.
The kits all have flat top pistons. With the 64cc heads on your Blazer. They will give you a compression ratio close to 10 to one. You cant go over 9.5 on a stock chip.
This is a better kit for a TBI budget stock/mild build. It is designed for the later one piece rear main seal TBI 350s

It comes with computer compatible cam and dished pistons which will keep the compression ratio under 9.5. It will run fine on the stock chip.
So you wont have to pay an extra 250 or more for a custom chip burn(s).
You can also add upgrades to it like better pistons, cam, ect,ect, by checking boxes on the bottom of the parts list.

Alright, thanks a lot thats the feedback I was looking for. Would you suggest doing anything else while the engine is disassembled? Heads? Intake? Just looking to get the best bang for my buck and do it right the first time while everything is easy to get at...
 
as far as i am concerned, it's not the price of the engine rebuild kit that's gonna be the issue, it's the machine work it's gonna take to get the new parts to work and fit correctly in the rebuilt block.

I am in the process of rebuilding a motor right now, i just opted for the machine shop to go ahead and do the whole thing, as piecing everything seperately like honing/boring, cleaning, piston removal and reinstallation to rods, resurfacing the crank, cam bearing installation, rebuilding the heads, was all going to be alot higher, priced seperately, than if i just let them do it all at once.

as it is i am getting my motor totally rebuilt, with upgraded pistons, moly rings, and even opted to have them install the roller cam and lifter setup in this motor for me, also rebuilding the heads with new springs and they are going to completely assemble the motor from intake to oil pan, for $1278.

Someone said flattop pistons are going to push compression ratio to near 10:1, interesting, because that's what is stock in these, at least in mine, it had flattops with valve reliefs and i read somewhere on the Summit site it would put it at about 9.35:1 compression.

the kit i found on the Summit site also was about a $359 rebuild kit too.

Personally, i would waste time on rebuilding a motor, unless you are going to do all the neccessary machine work for it to be assembled and close to factory specs for piston/ring and bearing clearences.
 
Hmmm yeah. I'm trying to gather some info so when the time comes, I'll be set and already have what I need and everything so I don't get held up without a truck for TOO long... I know this takes time and it is my DD so hopefully I can get it done without any issues

I agree....you can get cheap parts, but it may cost more in labor to make them work as good as buying the better parts to begin with. My machinist is getting me the better parts (SRP piston set, Engine Pro bearing set, etc.) at not much more than the kit prices, and he's happier using those, than the high production parts.
If your just replacing parts, go with the kits I guess, but if your building an engine to RUN....it would like the better parts.
