LT1 block and Heads

I have an 95 LT1 block w/heads. It's been bored to .30 over stock, but not honed. I don't want a stroker. So could I just get larger pistons to match the bore to rebuild the bottom end? Also I'm looking for 400-425 rwhp. Is this possible by doing a head/cam package? One last thing this will be my daily driver. Any thoughts appreciated thanks.

1st it need finished honed have it honed to fit the new pistons
2nd head/cam package will easily make 350-400 rwhp and be very streetable.

there no need to stroke it if you dont want us the stock crank and rods get some arp rod bolts though

.030 overbore with the stock crank and matching internals for the setup puts you at about 355ci. Dont worry about driving on a head and cammed car every day. I drove my friend's 93 Mustang GT with AFR 165s and custom cam running 12.14@111mph around and it was perfectly fine with the T-5 and 4.10s. His friend from school drives a 2000 SS making 454 rwhp on a 414ci stroker that he drives everyday including now.

Making 400rwhp should be very much conceivable. Its getting more and more common, plus it helps having a fresh bottom end. All you need is the right combo and theres plenty of sponsors on the board who can help you out.

Hey sorry for the late reply but thanks. Does anyone have any suggestions as far as What type of pistons, i.e. flat, dimpled etc? Also what would be a good brand to go with?

Thanks. As always any recommendations are welcomed.
