I've been looking for a while and that's all I've found. New LS1 crate
engines are available for $6k here;
http://www.paceparts.com/product.asp?0=308&1=311&3=56139
$5895 here;
http://www.sallee-chevrolet.com/Ascripts/pricesdata.cgi
An LS6 will put out 405 hp for about $2k more.
The problem is finding a PSRU that will handle > 300 hp.

The LS1 is under 400 lbs. As I recall the LS6 is 396 lbs and the LS1
weighs less that that.

Did you talk to Duane at Warp Drive? Perhaps they either have the adapter
your looking for, or they can build one for you.

Well I found out belted air won't handle 400HP. They refered me to team38. I
think EPI is looking the best so far for PSRU. I did find one place on the web
that offers Chevy SB that is machined instead of cast. It's stronger and
lighter than the LS1. As you can imagine it's 6K just for the block and it still
needs to be bored, clearanced and some other prep just to start adding more
expensive parts too. It would be over 10K easy but still an option. It can be
bored/stroked to get over 400ci so probably more torque than the LS1. Can someone
explain to me the effect of torque as far as airplane motor? It seems we all
we talk about is HP but as far as street cars go torque is as important if not
more so than HP. The other thought is changing the cam in the LS1 for a
profile that is maximum performance about 4500rpm depending on your psru should
help quite a bit for a couple hundred bucks.
Thanks again, Brad

Did EPI say they had a PSRU to sell you? The last contact that I
had with them indicated that there was somne other project in front
of it.
Nortwest-Aero's chevy belted PSRU is rated at 350 hp. I asked if that
was continious and they replied "until the fuel runs out". They
are also are selling a gearded PSRU for the Subaru but it's not
near 350 hp.
Real World Soluitions is developing a gear reduction drive for
higher horsepower rotaries such as turbo charged 13Bs and 20B 3
rotor engines. Will these hit 350 hp?

You may want to contact the RAA in Ontario regarding the Seabee with a V 8
[I believe an LS1] with a silent chain PSRU.
Witness's say it "goes like a rocket"

Check the above site for a CAMDrive PSRU rated at 350-500 HP... hope this
helps,

The RD-1B & C drives will handle 350 HP but they are probably not the right
ratios for the LS-1 or other V8s. B is 2.176 : 1 and C is 2.85 : 1. They
are both in-line planetary drives which would probably put the valve covers
throught the top of the cowl unless you inverted the engine.

<<You can get high quality aftermarket aluminum engines based on the
tall-block version of the bb Chevy with up to about 680 cubic inches.
One of these engines with low compression and a normalizing supercharger
or turbo might make a really good high torque, low rpm engine.

Lots of good comments in reply to the original LS1 question. My overall
conclusion of the reason one would put a conversion in their airplane is the
same one that justifies building the airplane itself - "because you want
to." There is probably no reason; cost, reliability, or whatever that makes
it go one way or the other. Fuel consumption is a wash, except that I
believe the rotary will still burn more than either other alternative. I
think that up to 300+ hp the small block can be built in a direct-drive
turbocharged configuration lighter and cheaper than with a PSRU. For 400 hp
a big block would be my choice. Above 450 a turbine would make more sense.

Well I checked out the camdrive web site. 11K for the psru seems a little
excessive. It looks like a real nice unit but it's 78lbs and expensive also.
Thanks for the link though I am getting a good page of bookmarks for research.
