horsepower question Hello everyone I own a 93lt-1 with some mod's already in, for example: milled and ported heads, cai, lt4 hot cam, 1.6rr's, march underdrive pulley,air foil,msd ign. 6al, msd 8.5 wires, ngk plugs, adjustable fuel pressure reg.,and finally a 3" exhaust flow masters which I am not to crazy about. computer tuned by next level performance. I had the car dyno'd at 305h.p./317.6torq. my question, I would like to reach at least 375 h.p. and up as well as my torq. what other mod's can I get?, in order to achieve my goal, 
anyones tips would be appreciated. p.s. my next mod's will be a set of long tubes headers how many horses do you think I can achieve with this.

well when you get the LT's you will need another tune and you should gain anywhere from 25-40 rwhp but im guessing since your heads are ported you may see another 40 rwhp, get a bigger throttle body, try to find a LT4 intake manifold(will be hard to find and vary expensive) that should be close to the gains your looking for.

i wouldnt go for a throttle body, probably just a waste of money. and i know exactly where to find an LT4 intake... have you looked in the summit book lately? edelbrock is making them now for 460 dollars, red and all. i think they are a little different than the original LT4 intakes but probably better

first off get the long tubes. secondly dont even consider an lt4 intake. youre not going to benefit from the lt4 intake unless you have a better set of heads. the only advantage of the lt4 stuff is the runner design. your best option after the headers is to spray it.

Horsepower GENTLEMAN thank you all for your advices as for right now I am just gonna get me the long tubes with some borla exhaust, and a set of 3.73 gears. And a good tune, to see where this throws me at. I will keep you guys informed of the results again thanks.
