Ok Guys,

This engine makes 719 HP on LME engine dyno. It was specifically set up to be used in a corvette for road racing.

I think it might work even better in a CAMARO using an A10 Tranny behind it. Figuring a 12% loss, this should make 630-640 to the wheels.

C8 Z06 eat your heart out

That is a bad ass motor... but id still rather have the instant torque of a blown motor... although I think id need to drive the car that beast goes into for a few days to be sure

Wow, had no idea those LME NA were that high in ponies. Amazing. Are you utilizing a different fuel system?

Dumb question, given the compression is so high, does this mean this particular set up will not be made adjustable for FI in the future?

Well I get you!! I had a ZL1 1LE as you are probably aware but I much prefer my NA engine and the way it is set up now for road racing. That instant SC torque isnt necessarily a good thing when you are trying to negotiate a series of corners trying to keep the car balanced and hooked up.

That makes sense... not that my car is making a ton of power, but i can relate that even 777rwtq is straight line power only... can be tough to modulate around corners.

Well my specific engine is roughly 14:1 and is uses much larger injectors and ZL1 fuel pump. You dont need as much fuel with a non-supercharged application. I do however run E85 which requires more fuel delivery than a pump gas set up by about 30%.

As far as forced injection goes, most people stay in area of 10-10.5 to 1 compression. I would imagine though it would be easy enough to LOWER the compression on the LME engine by using heads with bigger combustion chambers or by using a thicker head gasket or BOTH.

It is a common misconception though that BIG Power NA engines are LESS expennsive than a FI set up. They DEFINITEY are NOT.

Big power NA engines are definitely not cheaper lol. 427 over here. So youre running 14:1 compression with CID heads? IG vid said 12:1 CR so im just confirming. Will you be limited to E85 with that CR? What Intake will you be running? Can only imagine what cam is in there to make that ~720 peak.

I can run on 93 YES, but the timing is reduced progressively anytime the E content is less than E70. I would NEVER run 93 on the track though as I take plenty of E85 to the track with me in my tire trailer when I go. I would NEVER drive the car aggresively on 93.

I run GM heads but they have an AMP CNC port on them. The IG video says 12:1 compression on the LME engine NOT MINE> The compression calculations put my engine between 13.5 and 14:1 compression. I am running a ported MSD intake with NW 103MM TB and BIG MOUTH air intake. I CURRENTLY run the Gwatney Performance NFC cam but the cam I WILL be running is quite a bit larger. I am not too concerned about that because the compression and larger CI engine tames the cam somewhat at idle. The CURRENT cam idles fine in 105 temps in heavy traffic with the STOCK converter (A10).

I would love to get the specs on the cam LME used on that build.

[s346k]

to be fair, btr was posting 730 crank hp numbers a couple years ago using a stock LT1 shortblock and their 230 camshaft with cid heads & trinity manifold.

i highly doubt it would offer the rpm range & hold up to a road course like that lme motor should, though.

Yeah I know for a fact the camshaft that LME used is more in the 240 250 duration range I will try and get specs. You need alot of compression and a stroker motor to make it really streetable for a DD if you use that LME cam. The BTR set up was more for a drag racing application and it made alot of peak power but sacrificed low to mid range numbers.

The beauty of my application on the track is that it rarely sees less than 4500-5000 RPM with my A10 in track mode so if the LME CAM sacrifices some BELOW that RPM level then it doesnt really matter.
