There's an aftermarket (or is it GMPP?) block called the LSX or LS-X or something like that... Don's using a production block, so it isn't one of those.

The engine was an L92 from an Escalade and then was stroked with a 4.100 Callies crank,cnc'd heads,diamond pistons,Comstar connecting rods,Mast Motorsports custom cam,L76 intake manifold and all that made it a 427 with 621hp and 555 pd's of torque at the engine.I used the Ls4 waterpump,pan and harmonic balancer.
Thats what makes my LSX.

Not really necessary for threads in the Construction Zone, as they don't get dropped into the Archives, but instead stay alive. So unless one has a specific question or comment on the thread, there's no need to 'bump' them in here.

ON Sept 23, 2012, I disregarded my Dr's advice not to do anything that pulled G's because of bonespurs on my spine pointed at and right by the Aorta AND TOOK MY IMSA 427 to the strip today.I tried to take it as easy off the line as I thought I could get away with and still have good times.I also had the transaxle short shift at 6500 rpm rather than 7000rpm from first to second to keep G's down.But second to third it did shift at 7000rpm.So I know the car has faster times in it than it ran today.
!st run, I was just checking it out and did a 1.975 60 ft,at 11.520 and 115.63 mph.
2nd run,I did a 1.649 60 ft at 10.597 and 130.28 mph.
3rd run,I did a 1.555 60 ft at 10.519 and 129.92 mph.
Most people know what I'm running,but for those that don't this is what it is:
The car was built as a street car and has working air conditioning and nothing was cut to get the engine in.The interior is stock except for a 6 point roll bar,gate shifter 5point seat belts and Auto-Meter gauges.
It has an all aluminum 427 LSx engine mated to a built 2007 Impala 4T65E HD transaxle with 3:29 gears and a 10 1/2 inch 3000 rpm stall torque converter.It has a IMSA wide body with a painted Goodwrench logo design and white pearl paint.It has coilovers in the back.
The engine dynoed at 621hp and 555 pounds of torque.The engine was a L92 and was stroked a half an inch with a 4.100 Callies crank to get to 427 cu. inches.It also has CNC,d heads with a L76 intake.
I hope this helps you V8 guys out,now I know it CAN run the 9's,I just have to see if I have the guts to do it with my spine.
