400hp 350TBI advice
 
I have a 89 k5 with the LO5 350TBI and wanting to do some major mods to get as close to or more than 400hp with a somewhat high compression ratio around 10:1 give or take. This is what im thinking so far of course this isnt everything just the major things. What kind of output could i get with this combo or would it even work together or is there something better?

From what I've been told 400hp is pretty tough with a TBI, but possible. The cam will be very important as well. Other things to keep in mind will be possibly higher fuel pressure and computer tuning upgrades.

I was all ready planning to have a very extensive tune done but as far as the cam goes I have one in mind but what would be recommended for this setup to get the output I'm wanting
