Saber-1

Not sure if this is the appropriate thread but I'll give it a try. I'm a 67-year-old retired soldier living alone with my four pups. I'm a muscle car enthusiast, and I'm in a position where I can afford what's affectionally referred to as a 'bucket list build. I grew up in the late 60-70s. At the time I couldn't afford a 1963 Impala, so I relied on my 1974 Dodge Coronet with the 440 Magnum in my patrol car. I drove a few other big blocks and they were a blast.

I now drive a late model Chevy SS sedan, aka Holden Commodore, with an anemic LS3 w/6L80. It's a 4100-pound 4-door. I want to install a straight-up NA 427 or 440 on an RHS or Dart Next II alloy block. It will be my daily driver, and I don't care to win any HP contest; I simply prefer the sound and behavior of lager cubes that will be reasonably street-friendly.

Any advice on configuration is appreciated.

Hey Saber. First off thanks for your service. Second, what's your power goal and how deep are your pockets?

I have, as well as others on here, a full Mamo spec build that consists of AFR heads, Atomic intake, and 440 cubic inches of LS goodness. Mine, however, is in a 99 SS with full interior and the car looks stock still rolling on the factory chrome 5 spoke SS wheels. It's loud, it's fast, it's fun.

Are you planning to do the work yourself or outsource the build and install?

Thanks for the response. While I'm flexible on some of the specs, this is my basic config snd plan...

Power Goal: 675-685
Budget: $40-$42k
Desired Config: 440 NA / RHS 9.250 Deck

Do you plan to sell your current engine? If so, there are lots who would be in line for it and it would help offset some cost.

I did a pretty standard build. New Gen IV aluminum block, sleeved and bored to 4.185 and a 4" stroke and 11.9:1 compression. Bottom end is all forged with Callie's crank and rods and Wiseco pistons. Top end is MMS 265 LS7 heads with the Mamo ported Atomic intake and a 102 TB. It surpasses your expectations in power, is 100% brand new in every aspect, and is matched very well and Tony stands behind his work. Feel free to PM if you like.

650/650 built on a lightened 5.3 Texas Speed block, AFR, TS cam, Forged Racetech pistons and connecting rods, CNC'd + balanced and blueprinted stroked to a 383. Hot Rod Company - Turn Key Crate Engines For Sale (nwhotrodcompany.com)
Torque at 2100 rpm is over 500 ft lbs. and slowly climbs to 650 until 6300
At 6300 rpm the torque falls off FAST but by then it doesn't matter. This is with cast iron exhaust manifolds and a full OEM exhaust.
I can not exaggerate how great it is.
