Dart LS next block or GM LSX block?
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




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.
The Best V8 Stories One Small Block at Time
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.
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
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.
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

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.
