is there a link to ls7 block/head speck similar to this ls3 one
this is very informative for stock stuff and newbys anyway

http://www.camarohomepage.com/ls3/index.htm

 

i gather you are limited to 4.155 bore for fi with ls2 re sleeve and 4.185 for N/A reliability wise
is this the end of THE line for the block no room for future cleanup honing rebuilding ect ?

WOULD you be better of with as big a bore as possable and keep the stroke as short possable (still 454)for hi milage
would that keep the skirt in the bore with the wright piston rod combo



is the GM PERFORMANCE PARTS 454 crate WITH LSX HEADS as seen on seama show vido avalble yet dont seam to be much on there site price ect
GM PARTS say 4.25 bore on the new lsx extrem block
is this a newer version or is there only 2 lsx blocks high and std is the casting problem that thay hade a thing of the past now

 

Lots of detail there on the LS3 mate

Some here on the LS7.
Try and get a hold of the presentation last year at PRI for the ATEC from one of the GM LS7 team. Some good info on the extra work that goes into the LS7's

 

Doesnt the LS9 head have a thicker deck that would allow it to stand up to FI (obviously) or nitrous?? To me, this solves one of the major drawback of the LS3/L92 head. Can the exhaust on the LS9 head be made to flow a bit better then the LS3/L92 one??

 

nice little lsx head vido from seama

what are your thoughts on thease ive never heard of them over here in the bush

Good rings we were using them before Wiseco offered their GFX rings for everything.

 

Total Seal has been around a long time and specialize in piston rings. We use them allot on our big boosted/ large displacement engine builds because they have every ring you could imagine and can put any combination together for you. They aren't cheap though but worth the money in some of these big builds of ours.
Just like 99blancoSS said the Wiseco GFX rings will do fine on most Street/Strip builds.

 

thanks for that info
do you use the gapless or just standard ones
cheers

 

One of the recent engine masters magazines had a review of rings, the gapless ones were about 10rwhp better than the usual gapped ones IIRC.
