OK guys, now that I know the block can be bored to 4.00" with it pour filled has anyone done a 4.00" bore on a Chevy L6 250 block with the water passages in the block still open.
I really would like to keep the cooling system for the whole motor if I can and pour filling an L6 motor is not as easy as a SBC V8. The cost of sleeving the motor is out of my bracket.
This motor will replace my existing 194" L6 with a 266" L6 in my vintage dragster.

It is gambling, but many people has opened the L6 (250") to 4.000" and still kept the water galleries. It's also a factor where the block was cast (US, Mexico or Brazil) and how old (corroded) it is.
Lots of L6 info here:

I know where your coming from on this big of bore. Know anyone that has done this with the water jackets that I can contact?
It looks like a lot bigger job to pour fill a 250 L6 than it is to do a SBC V8. What say?

There are many different prohormones and anabolic steroids on the market today, so it can be tough to decide which one is right for you <a href=https://fastpriligy.top/>dapoxetine priligy uk</a> Bennett JM, et al
