Do the ERL blocks have the extra head bolt holes added?

The 6 bolt blocks are optional on the ERL blocks and work very well. I highly recomend The ERL blocks, they have been rock solid for me. I believe when you factor in the ERL comes ready to assemble you will find there true value. The other thing is ERL has a very high quality machining facility that specializes in producing the LS blocks, it's something that gives me a lot of comfort when dealing with them.

Can a ls crankshaft with the 8 counter weights from Dart fit in a regular oem block?

Yeah, but a little machining on the block is needed.

I heard the Dart block will have more fitment issues in an F-body and because of this the ERL or LSX is the way to go. The starter on the Dart is on the opposite side of the stock location of the LS1?
any truth to this? If so then; coupled with better strength and pricing wouldn't the aluminum 5.3L with ERL sleeves and machining be the best option for price quality and fitment for Gen 4 Camaro?
thanks in advance

anyone?

How much power you plan on making ?

LSX Iron Block has priority main oil system much more efficient
Than erl block but has a 135 lb weight penalty. Both will fit
Like stock compared to Dart. I went with LSX for oiling
Needs, most applications would prioritize weight savings VS
Oiling benefits.

Launch

I'm going with ERL when I move on from using stock bore sizes. I don't see an issue with the oiling.

As good as the LSX block are I can't justify the extra weight.

I do not like the dart blocks not being a proper cross bolted mains setup. I believe this is what gives the LS platform some of it's proven reliability.

650 rwhp is the goal
RHS LS7 307cc ported FRH
Crower rockers
FAST 102 ported FRH / NW 102 TB
Cam Motion LLSR
434 cu in (4.00 crank with 4.155 bore)
DP Nitrous Outlet 250 shot with dedicated fuel system (in addition to the N/A rwhp)

I have the entire top half of my engine and now looking to work on the bottom half; Hence, my question on the best block for my build

The oiling system is a nice advantage which is why I looked hard at this block. What keeps me going back to ERL is the machining, precision and reputation. My set up will be 98% street and some track for data more so anything else. ERL blocks really are a work of art...
my internals will be wiseco, callie ultra I CR and Callie DS crank
$$$ wise they're pretty close so i don't factor in the cost. I would rather work overtime for an extra month or two and get the quality over the here and now.

thanks for the input Tusk, Launch & Navy....
open to more ERL vs LSX opinions.

Dart is a great block but not for F-body so I'm looking to narrowing it down to ERL vs LSX
my 98 Z28, Dart block with 2" LT Kooks will pose some complicated problems in my engine bay compared to the slip in blocks of ERL and/or LSX

Thanks for the nice words... I would look into using a ERL block.... I'm going with racing engine development myself. Lsx blocks are just too heavy in my opinion. Look at this thread.... let me know what you think.

Dart Tech 1

With our blocks, you can mount the starter on either side. Our LS NEXT SHP Blocks are a direct replacement for the factory block. The only thing you have to do is convert to a Gen IV front cams sensor if you are running a Gen III rear cam sensor. This requires a Gen IV timing cover, 1x cam gear and an extension harness.

We are glad to help you.

ALL LS Next blocks have priority main oiling. The LSNext SHP block is a direct bolt in replacement and only needs finish cylinder hone. This will save you $$$ over the LSX block which needs additional machine work at extra cost and hassle. Also, our latest version oil pan adapter spacer allows your to run production style LS oil pans and is has provisions for A/C and power steering bolts. So, you can have iron or aluminum with Dart's LSNext block.

You will find no better or stronger block than the Dart LSNext. It is engineered from the ground up to be stronger and better than any other LS block you can buy.

Unreal

Interested in any updates to this. Looking at doing a new motor. have a 427 LSX now, but stepping it up a bit.

Another LSX block, or Dart Pro SHP. I see the dart guy said direct replacement, but I'm not sure if I'm seeing all the mounting holes for knock sensors, grounds, etc. I don't want to mess with that.

Thinking dart SHP pro block, dark CCW 4" long snount crank, some mast or all pros with big solid roller.

I have the aluminum Dart LS Next block and it was almost identical to my old LS7 block except for the mains are old school splayed. I guess more strength is needed and lifter windows in the valley were the difference though!

DART!! we can be twins..

can sort you out.

Also the new version of the LS Next SHP Pro is out cast in the better grade iron...

when i win the lottery, im going to build tall deck 440 with an RHS block, All Pro heads and a LLSR by cam motion and daily drive that **** on corn juice!
