Start with a sorta special small block. Add the marine stuff. Add stronger parts. Invent stuff to fill in the gaps.

Get around 500 plus ft. lbs. of torque at 3,000 rpm. That is is big block number.

What defines a special small block?

Super Charged ?

Nope.

Chevy all aluminum small block.

It sounds good. But, if I were buying, I would have to 'feel' it first.

I would like to see the torque numbers from 0 to 5,000. What is 'special' about this base small block you're starting with?

And, what kind of stuff are you 'inventing' to fill the gaps?

Oops, sorry.

Think Corvette type. This one is 434 cubes.

I am not inveenting anything. The selling engine builder did.

The scale of the torque ban over all rpms has not been disclosed yet.

Peak Hp is 550 Hp at 5,500 rpms. Peak torque is 565 ft. lbs. at 4,400 rpm.

Just for D-Rod, the engine builder uses electronic variable valve timing in this engine. Adjusts via load and rpm. Said to broader the torque ban.

Sorry, I didn't mean you seabuddy. I meant that in a more generic sense. "You", as in whoever the builder is. What are they inventing to provide more torque from a small block?

434 C.I.D. is quite large for a "small" block. Do you heve the bore and stroke dimensions?

Special engine crank, so, no, I do not. Think about like the numbers from that 7 litre Corvette engine.
