Jesse,
have you built a serious gen 3's in the 800-850 hp range? N/A of course. a couple of guys in my racing circle over here are wondering about them.
My upcoming build for my D150 5spd/Shorty:
New 6.2L Hellkitty Block Bore @ 4.125"
New 6.4L Steel Crank Offset Ground/Nitrited 3.800" x 1.850" Rod Journal Dia
Pankl 6.200" Rods/ .708" Pin
Custom Mahle or Diamond Pistons (Turnaround time will dictate whom @ time of order)
11.8-12.0 comp target
New Apache Cyl Heads with a little bowl work only and the just released Melling Spring Kit for G3's (Wow is this spring kit nice and comprehensive)
Summit BigGun 5743 Camshaft 244/251 .625"/.625" 116 LSA ( I want this driveable)
Comp Short Travel HR Lifters
Manton Rocker Shafts/New Stock Rockers although PRW has the new Hemi rockers available (I liked what I saw @ PRI)
Ritter DrapPack Intake modified W/4500>4150 HVH Adapter
Holley 950 Dominator GB Carburetion / Modified (Why a Dominator? 'Cuz I've always wanted one and this should be enough motor to warrant one)
Projected power should be well north of 600HP @ 7300-7500RPM Maybe 700ish if the planets align. Hemis aren't really known for great torque production and I'm just fine with that in this case. Probably make 550lbs. This will be coupled with a Tremec TKX so not interested in the stoplight drag scene. I live on a great, newly paved twisty hwy along the St.Lawrence river and it is populated in the summertime with all kinds of exotics and muscle (Porsches/Merc AMG/BMW's/Vipers/Pro-Touring Muscle/and disproportionate amount of VW Golf R's < which I find weird) J.Rob
