Hey id like to know your Setup. What style carbs, size of blower, Compression ratio, style cam, and what octane fuel. and id really like to know how you got that surging sound idle and if thats healthy for the motor. i heard someone say that only a blower motor running a fuel injected system can idle like that.. ? email, msyates436711@hotmail.com
what all is needed to build this motor? if you can give a parts list that would be awesome..i will greatly appreciate it im just getting into drag racing and would love with engine Thanks a Lot
well a 383 is a 350 block strokered into the 383. so get the 350 motor and get a stroker kit. everything should come with the kit. then get the manifold and carb and blower. probablly get flat top pistons too as well if your racing. and a smaller cc head if you can. i have camelback heads on my 383 and they are the best for the 350 block. so thats about it. cost a shit ton but worth it... bore the motor over 30 or 40. and get a good port and polish on the heads. i did my own for mine.
get a 350 block, take it to the machine shop have new frost plugs cam bearings installed, bore and hone .030 over, have the cam side of the cylinders and the outside of the cylinders machined to clear a 3.75 stroke (sometimes the oil tray surface too) get some low compression like 26cc inv dome forged pistons, assemble, throw some good heads on it (like afr 195cc which is good for what you want to do up to 6500 or so) get a blower cam with 230/236 dur. .522/.544 lift assemble with 2 650dp's n go
it is a 680 overall lift custom cam.... im running around 12lbs of boost... and the blower makes it idle like that, if you listen to it in person you can hear 3 revolutions of the blower between each surge of the idle
the only engines that I've ever heard idle that way have been blown and usualy on alcohol. so, it's probably a combo of the supercharger and the cam huh?
i would say that it is from the blower creating boost from the last surge/ the carburetors compensate with the pressurized bowls with fuel, the delay in all this causes surging as the engine idles. when the fuel that was slightly delayed reaches the engine bang, there goes the blower pulley= more boost= more compensation= continuing surging right? ( i believe the supercharger carburetors have a special pressurized circuit that compensate boost with fuel?
possible yes, most likely though its the cams in the motor. the cam is what gives the motor its pulse weather it be an extreme like this or a simple idle you hear on the road... this is probably a custom built cam the cylinders fire close together so you get a pulse then a dead spot, but at higher RPM is where it is much more efficient. look up some vids of drag cars, you will hear it more.
No, you are looking at the front of the engine. They put the headers on backwards because the dyno/control panel is at the rear and you dont want the exhaust blowing at you!
one more thing to add, there is NOTHING that sounds better than the right blower/cam set up at idle, for a car guy, nothing compares....well...maybe...you know...lol
yeah, honestly, 383 is probly the best way to roll. the 400 was a great power motor, unreliable as hell, so, you are combining the reliabilty of the 350, the stroke (torque) of the 400, good affordable, reliable street combo. i've three small block cars, one big block truck. big block...good for towing..lol.
hmm. pretty good. i just had a 489 BB Chevy built and it is not blown or 'done to the tits' and pulled 602 Horsepower and 592 FT Lbs of torque.. i dont know what i will make at the rear wheels, but a BB Chev would definetly fit in a Trans Am.. click on 454440 and you will see the video... :)

it might be that the blower is overdriven. Just a guess though.

right on, I never was clear what made them idle that way. I love it... goosebumps in person. lol
