Hey guys just wondering if anyone knows much on these motors. I was told they are 1000hp.

Motors are 604CID Nor-Tech 1000's GM Tool room bow tie blocks crower cranks 4.625 crower rods 6.535 Je coated Pistons bullet hydraulic roller cams morel hydraulic roller lifters Brodix heads t&d shaft rockers billet oil pump Keith black gear drives fluid damp balancers the blowershop 14-71 billet case blowers & intercoolers everything used was the best money could buy.

I'm wondering if I could pull the blowers and run single plane intakes and dominators and still make decent reliable hp/tq. I don't really want to get into tearing them down and changing things. Any input would be appreciated.

Ron probably built them. Maybe call him at Innovation and talk to him.

If they are nortech like the boat maybe check with HRE. Daryl harmeetman. He used to do/still does nortech big power stuff

That's correct as well, Ron Potter did a lot of their stuff in the past.
