408 or 402 Question A few questions, the search isn't working for me, and I've went through three pages hoping to find a few answers but I didn't.
I've done all the supporting mod, 12 bolt, built t56, sphoon suspension, etc. Now it's time for the most expensive part, the motor.
Few questions:
If I was wanting to build a NA 408 where I have a limited budget, but not too limited. I was looking at spending under 10k on the whole motor. Who would I look into for building a shortblock? I've seen a few NA 408 guys see 600 plus hp, is that possible on my budget?
What heads would I be looking into? What cam?
It's going to be a street/strip car, driven maybe once a week.
My goals are definately 600 horsepower NA, but if i can't reach that I wouldnt mind hooking my N20 kit back up.
Any other things you can inform me of would be greaT!
Sorry if this has been asked a million times, still in the learning stage here

Well 600rwhp will be very hard with N/A but if you really planning to spend 10k on the motor alone here is what I would do Call TSP (or any company you want) they have awesome price and great service I'm overseas and get a great service from them.
here is what suggest:
427ci LS7 Block with LS7 heads,intake and an aggrassive cam with High 11 CR You can get close to 560-580rwhp maybe more with good tune through an M6 Then spray the hell of it 200shot you will be close to 800rwhp and 800rwtq with this setup.
Good luck and Hope that helped.
