I recently bought a rebuilt lt1 shortblock and was under the impression that it was a stock 350, but when i got it home and took the plastic off...the pistons say .030
wouldn't this make it a 355???

 

hm....thats freekin wierd... all these years GM has been bluffing! haha Nice video though and NICE CAR!

 

So what you're trying to say is I don't have a 350 anymore? Now I'm all confused. J/K Just in case you didn't know, or had a brain fart usually when you do a full rebuild of a motor, you bore it .030 over making sure all the cyllinder walls are true

 

You got a better deal than you thought then. Rebuilt is better than re-ringed

 

well i guess that's pretty cool then. it's a good looking block, so i'm excited to do this. how much better would it be over the stock one? i'll be putting a cc305 in it and probably use stock heads(or maybe a very mild port...stupid sniffer test every year)

 

soooo...essentially it is a 355???

 

technically it is a 355, but it's still a 350 at heart

 

probably not much of a difference as far as hp/tq numbers is there?

 

not really anything measurable. But, basically you've got a new motor.

 

cool, now i just need to see how much i can port my heads, if I even can...lousy smog testing areas...

good thing it's "new"...too many miles on my current motor for a cam install...

 

Feel free to port those heads. That cam and ported heads with a GOOD tune will pass the sniffer no prob.
