93 octane might be a problem, I would hit up Reher Morrison in Tx for some wicked heads. They are very reasonable on the prices considering their fabulous outting in pro stock this year.
Anybody know what Heads and Camshaft it takes to make over 1000 Hp with a 547 ci chevy on 93 octane? Already have a 1071,superchiller, and 2 1050 dominators. Currently using Merlin steel heads,(early design), and a Clay Smith flat tappet,.640 lift cam.

You will need to go to an aluminum head to make that kind of power on pump gas.
Yes...Aluminum heads for sure and most likely a solid roller cam to spin that cid to around 6200-6500rpm.
That will get you to 1000hp.

BACK 4 MORE,
I figured it would take Aluminum heads and a solid roller,but there are so many different makes and sizes. Got any specific suggestions like make, intake runner size, cam lift,duration,and lobe centers. I turn the motor 6200 rpm now so 6200 to 6500 sounds about right. We run 8 to 11 pounds of boost depending on what kind of gas we are using. Not many people in my area to answer these questions. Thanks for the reply.
I like these heads...Canfield's standard 24.5-degree 350 c.c head. http://www.canfieldheads.com

I have a set of 345cc iron merlin/jenkins heads that have been cnc ported and will make the big power numbers in my 572.I hope to have it dynoed this spring.You can call goodwinn performance at 920 685 3000 and ask for todd.He has worked with canfield in R&D on there big block head.He has also worked with jim butler pontiac on cnc'd edelbrock heads.Good Luck!
VD Cruiser,
Instead of heads and camshaft, why don't you change the blowers? There's probably 100 or so hp left on the table when using that 1071. Cost would be a bit more for our quad rotor, but I guarantee, more power.
Thanks
Dustin
