with those mods, you'll need 10psi of boost to achieve 350whp

Yep, you might be close to around 250 rwhp with those mods.

what other mods can I get, but still keep my car reliable and a daily......Forced induction and nitrous is not an option......if i cannot acheive that then what can I realisticly acheive?

I also have been told to get a bigger throttle body such as 65 or 75mm and i was thinking of getting a venom chip which claims to add 50hp or so....and possibly a an e303 cam --let me know what other performance options I have.....

I have heard that the intake manifold will give me about 15ish hp and anywhere from 40-60hp from cobra cylinder heads and 10-15hp from headers and exhaust...is any of this true?

Thanks

you need a better H/C/I to hit the 300 rwhp mark along with a dyno tune

Expect to easily spend a few thousand in parts alone if you want to reach those goals. You won't make those numbers without some serious work - and even with these parts, I doubt you'll reach that number. You might as well sell all the parts you've accumulated and start from scratch if you're serious about that mark, because it's going to take ALOT to get a stock block 5.0 into that territory.

If i cannot reach that goal then that is fine for now.....I do not think that I am off to a bad start with
--cobra gt40 cylinder heads
-gt40p intake manifold
- flowmaster EXhaust
-K&n intake
-BBK headers
-3:73 (even though these don't add to hp)

I hope to soon have a bigger throttle body, and performance chip.....i am unsure of what those mods will put me at..... i might possibly buy a cam...what would be a good cam for low to midrange power??? I want something that will accelerate quickly and instantly..i don't need somehting that will add to top speed or top end performance....any help would be great......thanks
