Thats true .. felpro won't do any custom gaskets for me anymore. I had problems with the cometic .. felpro was the way to go.

LSX Power Tuning

I havent seen the aluminum one yet but have seen several of the cast ones and tuned a couple. The block is super nice IMO and Im switching to it for my new motor. One of the shops I do tuning for has built a good number of 440-460cu motors with the dart block. They really like the block and prefer iron over aluminum so I dont think I'll see to many of the aluminum ones.

How much does the 1/2 " studs upgrade cost for this block ?

I don't think it is necessary unless you're going to make over 1500rwhp. Threads are at the rop of the block plus 6bolt heads. Is it really worth the extra money ?

Point taken but you never can tell....what would start in one direction a lot of times ends up going in a different direction....and besides ain't nothing wrong with over building it imo.

Hi does any body know how much machining is required ie do the crank tunnels come finished would you just need to hone the bore to suit your pistons and zero the deck height

HAHA now that is funny! I have one of these blocks running in my car with about 70 miles on it. I used all LS specific parts except for the oil pan.

To answer your question : You will run a 24x or 58x reluctor wheel depending on your wiring harness of course.

Yeah, I heard that same crap about it running early SBC stuff. But, not true!! It runs all LS stuff. I reapeat...ALL LS stuff....water pump, crank, oil pump, etc. Spoke to DART personally. As stated earlier, you will need oil pan adapter rails if you are going to run a stock LS oil pan. Otherwise, with Canton, Stef's or Olsen oil pan you won't need an adapter. Thos aftermarket brands I just named bolts right up. Something tells me this block is better and stronger than the RHS.

The Guy in MY 99TA

there was somebody that was casting or in the process of casting a block that is/was to use SBC rotating assemblies w/ LS top end stuff. I dunno who it was or if it ever hit the market.

THIS BLOCK IS NOT THAT PRODUCT.
