Lighter BMR Kmember Do or Dont
Lighter BMR Kmember Do or Dont I will be replacing my 346 with a 6.0 iron block for my turbo setup. Is it worth buying the lighter BMR Kmember to offset some weight?
It seems as though the 6.0 iron block is close to 120lbs heavier than the LS1, do you happen to know how much wieght is saved with the BMR K member? I to am going this route, and considered also using the manual rack and brakes, for room and wieght savings.
I think the difference is closer to 80lbs. I think you save about 20 lbs with the tubular Ks.
I heard 80 lbs. heavier between the motors, and I don't know how much lighter the BMR is
i think what he meant was "why not use an LS2 instead of an iron block and K member" The aluminum will block will be lighter (and potentially cheaper after figuring in price of the K member) than the heavier iron block.

Texas speed and perfromance has a great sale going on now. If you are set on 6.0l displacement then don't bother stroking it but In my opinion I would get the aluminum block and then you can eventually lighten it up some more with the crossmember.

Verdad Gallardo It's funny you say that, because that is what I recall hearing as well. Then I had seen written somewhere recently that the iron block was something like 213 and the aluminum block was 93. Though, I don't know through experience. It would be awesome if it was only 80.

6.0 iron /LS2 aluminium I have a 6.0 iron block with a BMR K member. I bought it for clearance issues though as it really opens up alot of space underthere (FOR EVERTHING) LOL As for the LS2 compared to the LQ9 6.0 iron block? LOL Ide rather have alittle more weight with the iron knowing that if i ever hurt the engine,,,, i can just have it punched out alittle, verses spending the major cash having it resleeved and all the added bullshit that goes with that,is half of why i bought an iron over the aluminium LS2 The other half is strenth !

ACTUALLY ,,,If looking for even alittle more room up front on that BMR K member part #KM-013? ,,,,BMR just made me one,,,actually the very first one , which is this same part # ,but they installed the curved front turbo tubes in it from there turbo K member and it gave me a (whole lotta) more room then the regular LS1 K member and is stronger then the turbo K member IMO because its braced straight in the back were their turbo K member is curved front and back and heres some pics of it if intrested .I guess us APS guys are calling it the BMR APS K member (unofficially) LOLTalk to Lee at BMR if intrested in it

What was the additional cost for the "APS" k-member?
Also I am more into road racing than 1/4, what is the difference between the drag, turbo and road K-member?

btw, most forged cranks are lighter too right? same with forged rods and pistons? im starting to wonder if you cant break even with an iron block relatively easily???
i wish i could weight my complete new motor, but i dont have a scale to put it on
