I am considering changing my entire engine combo. I am looking to sell the top end, but would consider selling the engine complete. The entire package is and old Comp Eliminator setup from the early 2000's. It is dated, but makes good power and has been very reliable.
This top end just made 820hp at 8300rpm and 620 ft/lbs at 6200rpm on 414 cubic inch SBC last May on the Dyno at BTR Performance.
Engine has been 9.28 @146mph 1/4 and 5.83 @ 113mph 1/8 in 3240lb 72 Monte Carlo
The top end will include complete heads with titanium int and ex valves, titanium retainers, and PAC springs. Full set of Jesel rocker arms, with 2 spare int and ex rockers and various cups and adjusters. HRE sheet metal intake with dominator tepee top, as well as one for 4150 single and double 4150 top. Dart valve covers. Full set of Manton pushrods as well as almost a full extra set.
GM 615x 15 degree heads, rolled to 13.5 degrees. Ported by both Rons and Slawko on separate occasions. 41cc chambers.
Valves: Victory Titanium 5/16 stem intake and exhaust valves.
Valve Springs: PAC Racing 1248 Triple springs about 75 passes on this set. Have 3 other used sets for spares. Ferrera locks and titanium retainers.
Rocker Arms: Jesel 1.75 ratio intake and 1.65 Exhaust shaft rockers. Sent two seasons ago to Jesel for complete freshen with all new bearings, shafts and roller tips. As well as stress test on all rocker arms.
Intake: Custom HRE Sheet metal intake port matched to heads.
Push Rods: Manton 7/16-3/8 taper, at least 4 of each intake and exhaust extra, plus almost full set of extras from when I purchased top end.
Like I said above I would consider selling engine complete for the right price.
Block is Dart Little M with Billet Main Caps
Crankshaft is Bryant 3.800 stroke with Honda Rod Journals.
Rods are Custom GRP 5.85" Aluminum and Pistons are Custom CP with custom ring set. ALL NEW Bearings and Rings last May.
Crower Severe Duty 180 offset lifters
Moroso Oil Pan and Billet oil pump.
Engine is complete and can be heard running, just need to put rocker arms and Carb back on for serious buyer.
