Weight of the TA alum block is about the same as a stock 109 block.:smile:

I just weighed one and it was 104.5 lbs with the mains and fasteners bolted up and un-touched sleeves. If it were bored to 4.020-4.060 it would be considerably lighter. 109's are 115-120 lbs the same way with a 3.8 bore. An S2 is around 140 lbs depending on bore size and main configuration.

How far can they be bored? I have heard through the grapevine that you can't even go to 4.00 in.

I KNOW you can go 4" in a TA block!

Are you saying you only have .050 steel sleeve left ?

Don Wang should chime in here - he resleeved his last year and knows exactly how thick the ta sleeves are. Might do some searches for his postings to see if he has already shared the info.

And so I shall. If you like changing sleeves in an aluminum block at rebuild time, then go to 4.00". Personally, I found changing the sleeves to be the one of the most nerve racking experiences I've ever had to go through with a machine. I wouldn't recommend it on the first build up of a fresh block. Leave yourself some meat for the next freshen up.

That's what I'm saying, Lee. GB

Mine is a 3.913 bore (LS1 overbore).

The TA block is lighter than a 109.

I would have expected them to be quite a bit lighter than an iron block.

You can cut the block and re-sleeve on go to 4.060. I think the current sleeve is only good to 4".
