Tall Deck LSX
Tall Deck LSX If i run a tall deck LSX block in my 2000 T/a, what kinds of fitment issues will i be looking at? and will LS7 headers work even theo the block is about .25" taller, and .25" wider?
Thank you!
Thank you!
I know this isnt your question, but for Vette owners that may be interested, I've been told that the alternator may need to be trimmed a little bit to clear the now taller valve covers
I doubt regular headers are gunna fit the bill. Why would you run a LS7 header in a 00' TA anyway? That's a Vette header. You can get 454 ci easier than going tall deck. See sig.
Sorry, "LS7 headers" i ment by LS7 style headers, and if i put 454ci in the short deck i will need 1" pistons(skirt), and thats pushing it w/ the skirt on it, and the piston to rod ratio would be off also.

100% all motor, but i might spray a 150 wet shot when i go to the track, but probley not. Also if you have a 4.200" x 4.100" thats 444ci, to have a 454ci you would need 4.250" x 4.250". But i still am considering the Short deck with 438ci... if all else fails.

You are looking at way more than 15k for a lsx style big block.

So if i were to get a 482ci built all motor, with a sheet metal intake, 105mm tb, and warhawk LS7 heads, what kind of crank power might i be looking at, and same thing for the 454? Or is there more info needed?

At the top of that page there is a "tach" and it says "products and performance" underneath. Click on it. The whole first box is LSX heads. Click the one you want to look at and it will give you the info.

Seeings as how most LSX headers are very close to the fenderwell, and tuck up tight on the bottom of the car, I'd say they would hit in both places. As for the cubes, I'm not sure what borexstroke your considering, but mine is a 4.155"x4.185". The sleeves in my block are longer than stock to support the added stroke. As long as the builder and the piston manufacturer know what's going on, it isn't a problem. You could run a 4.200" x 4.100" in a LSX short deck for 454 cubes as well. It has a good ratio, although it isn't that important is you have a good builder. Are you planning on all out No2/forced induction or N/A?

You have no need for a tall deck. I'm on a list with a builder waiting for a tall deck LSX iron (9.7), but thats not for an N/A build
The best way to 454ci short deck, especially for a 100% N/A engine, is 4.185 bore by 4.125 stroke. Piston support at BDC is PLENTY.
If you want to spray it use a 4.155 bore, 447ci. The 8 cubes difference is meaningless in power.
Beast96Z,
When will that BITCH be running???????????????? Dying to see what the Harrop is gonna do.
