    Do tell more. I do like the idea of the TPI...but I'm still unsure exactly which direction I want to go with this ....

    So here is what I have ...





    Does anyone know if this intake can be redrilled to work with the early cylinder heads? I've heard of some places redrilling intakes to work w/vortec heads, but I know absolutely nothing about this thing ...

    If you are going junkyard, then a single turbo is going to be tough. A junkyard turbo from a 3000 rpm, 7.3L diesel only pushes enough cfm to feed 4400 rpm on 5.0L gas engine.
    A pair of turbos from a 2.3L Ford or a 2.2L Chrysler would be a better match. Less common, by also a good start would be a pair of the turbos from a 280ZX or the single turbo 300ZX.

    The image upload has never worked. Gotta to the photobucket deal.

    The upgrade we're eventually going to do (I PROMISE) will allow direct uploads.

    Back on topic....

    And you guys are sounding a lot like my going 10's for $2500 bucks idea.

    My idea is getting a 78-80 Monte Carlo/Malibu, stipping the car down to its basics and dropping in a Vortec 350(hydraulic roller motor) lowend from a junkyard, drop a set of good aftermarket heads on it and using one of these turbo kits off ebay and a blow-thru carb.

    He means "Speed Density" - they actually came with a closed loop setup if you wanted to use it... I'm thinking there's no MAF but instead a MAP sensor.

    Dude, if you have a ramjet intake lying around - case closed. Let's get it on!

    You sound scarily similar to my 283 build. I'm leaning towards a single too, but it depends. I think a single is just as easy to plumb exhaust to, but some people say not. The advantage to twins is that I can get smaller turbos and stock BOV and wastegate stuff because it is only controlling one of the small turbos, not some big one. We'll see.

    Well it just happens that I realized that I have a complete Ramjet 350 intake up at the shop ... manifold, injectors, fuel rails and MAF (?). I'm thinking this may be the answer ...

    One question: do I need different heads or can the ramjet intake be redrilled to match the early heads?

    On the turbo ... anything more expensive than almost free is too much. I'm leaning towards just a single as it will be cheaper. And one more rule, it can't be a kit ... this is low buck, make/build it in the garage.

    I would just go with a single Masterpower 70 turbo. Twins are cool but just remember that you have to buy two turbos and twins create alot more heat. My friend has a Grand National street car with twin 88s on it and the underhood temps are crazy.
    As far as power? Ill bet that your 307 with a single 70 on it will make well over 300 to the tire and get real good MPG. Just think about a Buick 3.8 V6 NA makes about 140HP and I have seen them make well over 500 without touching the motor and take a look at those motors. There nothing special a. My T type went 12.0 and it was dead stock with just a couple little bolt ons.

    as the boost make the small c.i.d. act bigger than it is.. and that requires more fuel..
    so, I'd think sizing will require knowing what rpm it will run at, at hyway cruise(mph)
    to have a balance of power and mpg.. untill you drop hammer.. then mpg goes out the window..
    Being the motor is a 307and he wants it to be a street car, I think a pair of T3/T4 hybrids would work real good.

    Look on Ebay there are TONS of turbo kits for SBC's. Prices range from 1000-1500 bucks.

    And took through the different kits, some have more pieces than the others and some come with an intercooler and some don't.
