How much HP is too much??? The key is stock bottom end...

[Piston]

Right now I got 325rwhp and about 385hp at the fly wheel. I belive more can be tuned out of the sob but that's all that there is for now. Currently this thing ran the best of a 13.2 with my 18inch wheel and tires that do not grip for **** . However, I have been thinking I want to hit 450rwhp and I'm thinking about putting a blower on the damn car. The only thing holding me back is I'm worried about losing everything when a piston or rod comes flying out. How many of you guys out there are running on stock blocks with insanse horse power numbers???

I'm curiours because some of the things that crossed my mind was a 393 DSS stroker. Howerver that would be too expensive for what I want out of the car. The block itself is cheap but to put it in my 94 with all acessories it would be a pain and costly. I have considered a 351 option but I just don't think that would be all that much horse. The best and cheapest option for great numbers is a blower. Let me know what you guys think.

Thanks.
