Here is one of two that we have built out testing last weekend.

What size ls is it?

Care to share what size turbos those are? Looks similar in size to mine(62mm)

Does the 900 stand for 900hp?

27 Daytona

Yes, the 900 stands for 900HP.

The turbos are a custom hybrid built to match the engine.

I can not see how anybody can compare BBC to a LS motor

BBC if setup right is 632 ci
A LS engine is 496 ci
Can the ls be made bigger and still work reliably?
I dont know what the engineering improvements of what makes the ls better but a well made, balanced bulletproof big block with the best stuff should be as efficient and more powerful
I prefer raw CI instead of some engineering improvements

im not sure where youre getting your info from. but there are plenty of well set up BBC's not 632 Cu In and LS engines generally are not 496cu in either. most LS engines are withing the 360-427 range

I know the bbc does not have to be 632 that is the largest option and I know almost nothing about the ls engine I am now just studying it

I know for 600 hp builds the ls can be good but what about for a 1200 each side build.Can these engines be built to 1200 hp with pump gas either twin turbo or procharger and they last long.It seems like the ls engines is more fuel efficient than a bbc
Steve Smith engines makes a 2000 hp ls engine but that is for a car and for short runs of power I think
