im going to just build the engine. i have a nice tax refund plus some $$$$ saved up to do so. heres a list of what i want to do.

stroke to 383
port intake
port heads
5 angle valve job
ferra valves oversized
doubble valve springs
forged rods
forged pistons
forged crank
bigger injectors
arp head studs
arp main studs
arp rod bolts
melling oil pump
csi waterpump
deltec ignition system
msd 8.5mm plug wires
58mm tb
high flow maf
bbk underdrive pullys
aluminum radiator
adj fuel pressure reg.
holly fuel pump.
vortec super charger
gm high performance timing chain kit

what i need to know is what cam to use and what headers to run as i have dual dynomax bullets already.

 

why? from what i have seen on here and a few other lt1 boards the 383 guys are cutting the better times in the 1/4

 

also what would be a good compression ratio to use the guy i talked to here at a local machine shop said 9.5:1 would be best but i dont think so

 

For a supercharged application, I certainly wouldn't go any higher than 9.5:1, I'm right at 9.0:1 for my setup below.

Be ready to get your wallet out, I hope you realize that's about $11k (conservatively!) worth of stuff by the time you're done...assuming there is such a thing.

 

there is a engine builder here called carolina machine engines that will do all the internls and head work for 2200 bucks thats including machineing,balencing, parts and labor. it may help to know the owner. my estimate form what i priced on every thing is around 7 grand and i have that saved up. and before i get bashed and told the stuff is junk there gonna put into my engine here are a list of the parts and manufacture.

forged rods eagle
forged pistons je
forged crank eagle
bigger injectors rc
head studs arp
main studs arp
rod bolts arp
oil pump melling
waterpump csi
main berings clevite 77
rod berings clevite
cam berings clevite
timing set gm

 

Go 9.0 :1 compression. Get a custom ground cam since its gonna be blown. It would be stupid to spend all that money and get a off-the-shelfer when you could gain so much more power and drivability spending the extra money for a custom grind.

How many lbs of boost do you wanna run it at?

 

And go with a set of coated longtubes for it. Pacesetter's are awesome for the price, mine fit perfect and the install is alot easier than Jet-Hots. With Jet-Hots and Hookers you have to cut part of the K member. Pacesetters have better ground clearance then any other long tubes too ... Except maybe TPiS or Kooks ???

 

What performance numbers are you looking to achieve? Do you already own the Vortech? Is your car a M6 or A4?

 

well that was gonna be my next question how do i tell if it is an a4 or a m6 i dont know what these denote? and im looking to be in the 450-500 hp range but if 550 is achieveable with these mods then i would like to get there.

 

a4= automatic 4 speed
m6= manual 6 speed

 

thats what i thoiught but i didnt wanna say it and be wrong
