Kicking around the idea of "building" a motor. I would like to start with an assembled short block and turn it into about 650HP wet sump so that it could be used in a modified or late model. Slightly underpowered I know but plenty of motor for tracks it will see. Also just trying to dodge the cost of a dry sump system at least for now.
I'm looking at the following short block assembly:

I figured with the H-beam rods and 4130 crank it should be a pretty reliable piece. As you can tell, I'm more concerned with reliability than I am performance. I'd rather have 650HP last me 1000 laps than 800HP last me 500. If this build is a success we might try something more aggressive.
Then not sure on what heads but would like to stay 23 degree to keep it simple as far as matching other stuff. For sure aluminum heads for weight savings and then REALLY not sure on cam but realize that will depend on head selection. Leaning toward AFR heads for business reasons I won't get into. Suffice to say I would have to get some REALLY compelling reasons not to go with AFRs for the price I can get them.
I'd like max HP in the 650 neighborhood and would like to spin it close to 8000 RMP if necessary.
Am I on the right track with this?
Initial budget for the whole project is going to be about $12,000.
If things go right and the motor holds up, I would be open to going through it and putting 18 or 13 degree heads on it to see what it will really do but want to start basic if possible.
How much compression do I really need to make 650HP?
