    They said on instagram its rated for 800hp at the crank. That’s about 680 to the tires for 10k. My stock lmm short block made it 500ish passes in the 500-660whp range until it cracked a piston. Is that 10k worth spending?

    Their ratings are at the crank. So 800ish at the tires

    I could have sworn they said mahle Motorsports. They’re claiming it’s an 800hp motor to the crank. I’d rather roll the dice with a factory lly short block.

    S&S street fighter engine dynoed

    What’s everyone think about this? They seem pretty happy according to their instagram posts. Made 1250hp 18xx torque on an engine dyno after 78 runs they cracked a piston. How long is an engine dyno pull 10/20 seconds. So their motor lasted 13-26 minutes at power, very few of those being over...

    4.3 V6 Turbo????

    The syclone my dad has bent the rods at 22psi and never had head gasket issue. I do think it bent the rod from detonation though. Not sure what trans was in it but it was stock and ran 12.9
