Coming from a LS1 racing background, I can tell you that the motors are extremely reliable and MAST has been in the LS engine game long enough to know what they're doing. One motor I ran was a stock long block with boltons and a 150hp shot that had been raced every week for 70k miles. When the engine got a heads/cam swap, the cylinder bores still had the factory cross hatching marks with 105k miles on it and the motor has yet to die or make a noise.
The one thing I can say is to STAY AWAY from a aluminum LS1 block that has been big bore sleeved! MTI and ARE were doing this in the early days of the big cubic inch wars and alot of them ended up dropping sleeves. Go for a 6.0L iron block stroker or LSX block setup if you want bigger cubes.

I emailed this outfit to see what the pricing was. They replied very promptly. Here is what they had to say:
Final pricing has not been established, but we are targeting a complete engine with headers and accessories should be in the neighborhood of $30,000.00 retail. The engine will be rated for 6200 RPM max with 600hp and 570 Ft/lbs.
We should know much more in the upcoming months as we prepare for a late 2011 release date.
I will keep you on our contact list to send info as we get it.
Thank you for contacting Mast Motorsports,

Finaly on the dyno ,having lot of problems whit the calibaration but have now 540hp and 535 ft/lbs tq from 4000 to 5500 rpm but will find a little more after the fine tuning .
I think the cmi's take some hp because there 's no murch collector in what the ls engine likes .

Yes it comes in the phantom (uk) attach to a Blackhawk drive ,
the boat is normally outboard but I have it converted to inboard as well as the complete inside construction ,new stringers,transom and a bulkhead in the front,because that was very bad wood and mounted ,so basicly build a new boat .

Might help a few people here on OSO if you would convert the numbers to HP and same for torque numbers shown in NM so they could relate to the outputs better here in the US.
thanks,
