Oops sorry, I thought I read they were aluminum. Steel makes more sense.

Twin O/B Sonic

They came out w/one same/similar a yr ago but was a drag motor.

Same motor?

hogie roll

This is that motor. Not technically a drag motor. Low compression and medium cam lift.

Here’s a more race engine. Near max effort on the standard bbc 4.84 bore space.

the new trend in blown promod is 5.30 bore spacing allowing way oversquare big bore, shorter stroke. the engine is 2 inches longer i believe, it uses all special heads and can easily attain 1000ci with all cnc billet products. i dont think they will stop there

seriously wow had no idea. So they cant be tagged and registered for the street ? That sucks.

iliveonanisland

I figured it would be fairly easy to make 1.5hp per cubic in n/a. My 540 does that. But I guess when you get into larger displacement engines it gets more difficult

iliveonanisland

thats some seriously expensive hard parts
