90 mercruiser 7.4 mags
 

What kinda hp would l expect. Stock. Ported. Heads. Airgap. 10.5.1
600" hyd roller. And. Headers ?
Also. Would. There be. Any. Benefeit. To. Balancing?

This is the for sale thread? I think your looking to post in the technical section.

I'd guess 475-500hp. If you are changing anything in the rotating assem then your rebalance. If not, it won't hurt to balance but if you arent doing a complete teardown I would not be concerned not balancing. You should make sure you can get away running that compression with iron heads and 93oct. It seems a little close to the edge.

Sounds like the stockers. Can. Breath. A. Little. Or. Don't. Waste. The. Time

10.5 10 try and run alot. Of. Advance

Probably run. Octane. Booster. A. Little
I guess Arp bolts. And. Go.
What. Would. You. Say. Would. Be. Safe. Max. Hp. For those. ( stock. Bottom. Ends

500 550 aside. Should. Move. A. 30'er. Pretty. Good

Need. Iron eagles. And. Some. Lightened. Balanced. Pistons. And. A.
Hone

Off topic but is there a reason for a period after every single word? Just wondering.

I don't know dude ? It. Just. Starts. Doing. It. Like. Now
