should be able to get 900 HP out of 632 pretty easy.

1.42hp per ci, without a supercharger, can be done, but don't think I'd call it "easy".

It's definitely not going to be a low lift, smooth idling, low rpm, low compression, long valve train life engine. Now, something like a 572-598 setup, with a good rod ratio, mild hydraulic roller cam, good cylinder heads, a 10-71, 14-71......can be very docile, have good valve train life, meet your power goal easily on low boost.

As long as your cool with running a big solid roller , big compression, tunnel ram set ups, Should make for some wicked sounding engines. How long would you like to get out of your valvetrains?

You can always try Sonny's for a top half kit. Use it with a Brodix 5" bore space block.

900 is easy with a 632. Gonna run about $16,000 for all the parts.

Don't forget to talk to your drive guy about all that torque a large motor will produce.. Spin it to the moon to help save the drive.

You should sell him your 11.625 block, would help with the rod to stroke ratio.

Now we're talking. Good for a 5 to 5.5 stroke

I would use a block taller than 10.2 to build the 632. That way you can put a decent length piston in it.

No problem, a 598 will work as well. You could do it with a 572 if you want to turn a bit more rpm. Talk to Bob Madara about the valve train and overall combo, he has several customers running similar power. I know Wet vette on here has been running probably closer to 1000hp NA for many years. I have helped a couple of Bob's customers convert to EFI which will really helps with the dock manners, idle, in and out of gear, etc. As long as your heads are up to the task, the rest is fairly basic. I wouldn't run any taller then 10.2, those foot long pushrods are a killer. Call Bob - Drink now ICDEDPPL

1000 HP N/A, that's a lot.
