Who is currently building a 427 longblock (could be either ls2 or ls7) that is the best bang for the buck? I see so many options available that any opinions would be greatly appreciated. I would like a package that is capable of 550-600rwhp.

 

I am in the process of doing the same thing and have been researching the heck out of this (427 LS7) and all of the following folks are in my top 5 and not necessarily in this order:

Scoggin Dickey Perf (SDPC)
LME
Canadian Performance
Erik of HK Enterprises

They all build a great 427 LS7/2 for a great value and call them and go with the one who gives you the best feel and pricing and customer service, etc., etc.

 

What price range have you been getting for the long blocks (ls2 & ls7)?

 

Here is a recent post i started and I would say you will be hard pressed to beat these prices for a bang for the buck LS2/92/7 shortblock:

HERE YOU GO BRO:

Just got my newest edition of GM High Tech Performance today and see that Scoggin Dickey has released their new LS2/L92/LS7 "Big Bull" short blocks.

Man these bad boys look tempting at these prices and what do you guys think about this which I will quote from the magazine all utilzing the new SDPC/CALLIES 4.1 crank. It is my preference to use a 4.00 crank in a big cubes LS series motor but I would think these bad boys would be reliable in a full max effort N/A application that I am looking to build with Trick Flow 225 heads and a nice aggressive street/strip cam making around 11:5 to 1 compression.

HERE YOU GO and let's get your feedback as this is exciting ****:

LS2 block, 4.005 bore, 4.1 stroke crank, 413 cid for $4,569.00

L92 block, 4.068 bore, 4.1 stroke crank, 427 cid for $4,929.00

LS7block, 4.125, 4.1 stroke crank, 440 cid for $6,289.00

"All of the above big bull LS engine short block by SDPC features the new SDPC/CALLIES 4.100 stroke crank, manley forged pistons, scat H-Beam Rods, and a new GM alum Block.

Man this **** is tempting but a new 4.1 crank makes me a little leary as I have had a new Callies 4.125 crank several years ago fail on me and have SWORN I would never go with an ls series motor that was not a simple 4.00 fast reving, battle tested crank, but I am sure that could be offered at these same type of prices (and probably lower) by SDPC, but of course that will not the cubes set forth above down a bit.

What do you guys think? Man, this **** is getting really exciting!

At thes prices one could almost afford to put on a ported LS7 intake and CNC LS7 heads onto this 440 LS7 "big bull" LS7 motor, which should make close to around 575 to 590 rwhp!
