Chevy 305 TBI

[Mike Paraskoulakis]

Gentlemen

I have a 93' C1500 with what I believe has a 305. The VIN tells me it had the 4.3 from factory and I reckon someone swapped it before I bought the truck. So until I pull it out where can I find casting numbers? Considering it is a 305, an economical tbi headache, is there anything I can replace with after market parts? Nothing crazy. Is it worth a rebuild? It is currently bolted to an NV3500 5 speed. Any ideas will help.

thanks

Casting numbers are located on the part of the block that bolts to the transmission. I can't remember which side, but are facing up on the rear of the block.

Theyre on the drivers side

Is the 305 worth a small rebuild or just find something else? Perhaps a 350?

That's a tough question to answer. Factors like budget, intended use, expected life, expected performance all play into this kind of decision.

I had a 90 305 TBI it had over 500 000km and was stupid good on gas but was very tired and gutless I'd swap it to the 5.7TBI.

My 305 has been through hell
With neglect and half ass repairs over the years .... come on it's a 305

But I'd only swap if replacement was a built LS
And that's what I'm building now!

Id just run it till ya have problems with it. Then yank it and see what you can do at the time.

You don't even know if it's a 305 at this point. Find out what it is first and then make plans.
