Not with the right engine builder, now internet jockies it is actually quite routine. I just posted a couple examples where real builders can get it easily.

What's your point, what does this have to do with anything?

Years ago, I build a 383 for my C4, and it dynoed 330rwhp. It was quite an eye opener.

So basically, you took internet advice and built a crappy combination and it didn't run worth a shit. GM crate engines with a crappy little cam and fast burn heads put down 400 CHP. I now see your problem. You get your advice from the interweb.Quote:

Remember the LS7 427 makes about 490-520 chp stock. One of the biggest reasons why it's so efficient and can pass emmisions with flying colours is because it has a very small cam with heads that flow 335cfm plus.

Where do you get this stuff? Are you sober when you write it? Are you from Canada? Just wondering...

You went the other way, bigger cam, with much weaker flowing heads. Very much looking forward to seeing how the car performs. Last big stroker I saw was a 434 with a solid roller with 235cc heads, and stout compression. It made 515 rwhp which was a tad over 600chp.

Oh I see, you're one of those. Do us all a favor, don't give anyone advice here..

Let me get this straight, you SAW a 434 with heads...interesting. Nothing about the cam, tune, etc...it was all about head flow got it. That was a shitty combination if only put 600 HP. More evidence that internet advice is worth the paper is written on. Ask Pr0zac.
