    C4 383 - 100 Horses Sleeping at Rear Wheels

    The stock '85 conver can flash up to around 2600 rpms or so....for now i'de just stick with the stock converter and go from there.

    Throttle body differences

    The superram packages all rec. 58mm throttle bodys. I have one of LPE catalogs that confirms this from the late 90's. Even their 350 LT1 package rec. a 58mm throttle body. http://lingenfelter.com/pac350cidlt1y.asp

    ProCharger Supercharger

    Its pretty much what it is.....58mm throttle body, super ram intake, procharger, hooker headers, and a chip ( i forget from who....i'll ask) and a 3.07 gear. Everything else is stock....im not sure on boost levels..i'll ask about that too.

    C4 383 - 100 Horses Sleeping at Rear Wheels

    Thanks for the compliment. Beach Bum has one of the quickest sr/383/afr combo's around and I think he was running the stock '85 computer. With your DFI, heads, and higher compression I dont see a problem hitting 370rwhp. The torque is gonna be killer though. You'll definetly run 11's w/o a problem.

    Throttle body differences

    Its not going to kill throttle response with a 58mm throttle body. LPE rec. that all of their super ram upgrades, even on a stock motor, use the 58mm throttle body. I can only imagine so because the plenum is so large. With that being said, i'de look at the Holley 58 mm throttle body over the...

    well look at the bright side...at least you will be driving one very powerful 383 very soon. I've seen similar 383 s/r,74219/afr combo's put out ~360rwhp. You should install that 74219 cam -2 degrees and it should make peak hp around 5600 rpms. Im going to say with your heads and higher...

    160 Thermostat Where You need a heater

    you can always put a piece of cardboard or such under the car where the air enters the radiator area too keep the motor running warmer in the winter if you use a 160 stat. I personally like to see my coolant temp around 180 to 200 in the winter time and between 170 to 190 in the summer.

    C4 383 - 100 Horses Sleeping at Rear Wheels

    my 357 made 353 rwhp with a somewhat restrictive exhaust (2.5" non mandrel bent and bad cat's) now I have a 3" system with new cat's on the car. Hopefully i'll pick up another 10 hp or so. My gear is way too high for my setup which is a 3.07 dana 36. I've never had the car at the 1/4 mile but...

    ProCharger Supercharger

    One of my neighbors has a '88 vette auto with a superram and a procharger (believe the P600) with the air to air intercooler and a set of hooker headers. That is one fast f'n car.

    stock crank.

    8388 I could not agree more. My engine builder told me that if and when I run the 175hp shot of n2o my tune better be on the money because if it starts knocking then its gonna blow.

    Headlight will not rotate.

    My driver side headlight will not rotate. The light does come on though. What should I do to troubleshoot this?

    stock crank.

    Sure will. I spin to 6300 rpms and make about 450hp (gotta get back on the dyno with the new exhaust to confirm it) without a problem. Plus my motor was built for n2o @ 175hp shot max. So that equals about 625 flywheel hp. But I have never used n2o.....

    C4 383 - 100 Horses Sleeping at Rear Wheels

    Welcome to the "i've been screwed over by somebody who is allegedly reputable" club. It happens to the best of us. Glad you found out what is wrong with the car. Personally i'de ask your mechanic for a local engine builder who is reputable and go from there. Good luck.

    Dynoed Sweet Sin

    Did you buy the car used? Maybe the previous owner did some work on it. Reason I say is that I dont see the mod's in your sig. adding almost 60hp.

    Hood prop conversion...scissor to gas strut installation question????

    well I got the gas strut in. For the record I ordered a gas hood strut with the brackets from http://www.vette2vette.com for a great price. It was only $55 shipped to my house!!! This is a used gas strut from a LT1 Corvette. It took some minor drilling on the mounting bracket but it works great...
