10 second 406 engine for sale! - fresh!!

GrandSportC3 · 06-24-2007, 11:15 PM

406 engine, just freshened up

400 block, bored .030 over, 3.75 inch stroke Eagle 4340 forged crank, Forged Eagle H-beam rods, Clevite 77 bearings, Probe flat top pistons

Pro Topline 235 cc aluminum heads, fully race ported and flat milled to 56 cc chambers with 2.08/1.60 valves and > .700 lift springs

Solid roller cam with 261/270 degrees .050 duration and .625 lift (about .660 with the 1.6 ratio rocker arms)

Edelbrock Super Victor 2825 CNC ported intake (that's a $550+ intake)

1.6 ratio roller rockers, stud girdles

Balancer is a light weight Romac SFI 18.1 balancer

approx. 13.5 : 1 compression

Engine was just broken in on the dyno and was dyno tested and dynoed in at 590 HP and over 600 ft/lbs of torque with 1 5/8 headers.. The engine will make over 600 HP with large tube headers.

Machine work, engine break in and dyno testing was performed by a very reputable local shop (NELSON BROTHERS). (I can provide phone and address of the shop to verify what work was done by them)

This engine should be able to take a 100 shot of nitrous.

Before the rebuild, I ran 10.35 @ 127.59 with this engine in my 3000 lbs '68 Corvette (on engine without nitrous).

This engine is complete from intake to oil pan. The carburetor used for the dyno runs is a 80514 Holley HP series 1000 cfm carb (annular boosters). A 1 inch HVH spacer was also used for the dyno pulls. The ignition used for the dyno pull was a 65000 Volt HEI ignition.

The carb and ignition are NOT included. The carb (which was tweaked especially for that engine) is available for additional $450 (that was a $770 carb when new and it's like new) and the ignition with the bronze gear is available for an additional $100. (brand new, only used for dyno pulls)

I'm selling this engine as I went with a 434 engine with a big shot of nitrous.

Asking $5499

I'm only trying to get a fraction out of the engine what I have in it...

here are 2 runs with that engine: (before I freshened it up)

10.35 @ 127.59 mph on engine

10.07 @ 131.82 mph (spun a rod bearing on that run - would've been easily in the 9's without the spun bearing). The spun #1 rod bearing was also the reason for the rebuild..

car is 3000 lbs with gas and driver..

Mackey should be all over this.......

Joe, when are you gonna run that poor engine? Just have Oliver deliver the 406 that Monday

_twisted_ · 06-25-2007, 03:27 PM

it might be fired this week

I made sure I don't have any juice laying around so I don't go crazy for a few miles.

After it's running it still needs the exhaust and an alignment.
