    I am going to be using the stock fuel pump to get it running and then switch out to a ractronix fuel pump kit and reuse a stock fuel pressure regulator. I have a 383 bottom end with LE2 heads. The less stuff you change at the same time you do a head and cam or entire engine swap, the less you have to question. They can tune it for NOS but I would do that down the road on a dyno tune after you break it in and sort out all the bugs but thats just me.

    I have 30lb injectors on my car with LE2 heads. You don't need a new fuel pressure regulator. Your tuner will dial in the fuel pressure, but the pump really needs to be changed. Run your engine lean one time and you can say goodbye to it.

    Some good and not so good in there but what bottom end are you going to be running? Stock bottom end with the LE2 and one of his custom cams will get you very close but the compression has to be some what high.
    I looked at the Trickflow 185's with the 54 or 56 cc chambers and they made right around 350 or so at the wheels but that was thier cam grind and I don't remember what it was.
    Edelbrock: People say don't bother.
    LT4 you can do it but having the lt1 heads worked by Lloyd or advanced is going to make them flow better than a stock lt4 head or edelbrock lt4 head. not to mention you have to buy the lt4 intake.
    Advanced induction can do any head you want and make power out of them cuz they flow them like what Lloyd does, BUT be ready to spend a bit more with them. I got a quote from them for a set of trick flows and the entire top end was going to be just under 5K smackaroos. It would be realy nice and done right but I just did not have that kind of a motor in mind.
    Trickflow heads you better see if you can find them right now. Summit ran out of the 185's and said they have no clue when trickflow would be running that head in production again. the 195's are really ment for blower and NOS apps unless you are going to have a piston in it that will boost the compession back up. you need to stay at 10.5 to 11.5 for N/A , only way to make the power on a 350 unless you add a blower or nos.
    Another head you may look at is the AFR's or Air flow reaserch heads. They make a nice head as well and they flow great numbers. I guess what I should have said is you need heads that are flowed or flow very good. Thats were the power comes in. but you have to know what bottom end you are going to have so you can get the chamber volume right as well as the clearance you need for the valves depending on what lift cam you are going to be using.

    Put LT headers on it and call it day untill he can do it right. If it is high millage no sense. If low call Advanced induction or Lloyd Elliot, or buy an out of the box kit like the trickflow system, or air flow reasearch heads.
