I was told it will need the same machining as if you purchased a dart block. Will come bored to a 4.120 I’m going to have it set up as a 434. 4.155x4.00
going to try and get about 750hp to the crank out of it. Shafiroff seems to have little problems turning out 750hp from their 434 long blocks. Figured with 13.5:1 with another LLSR cam shouldn’t be too difficult.
MAAAAAN!! That sounds like a KILLER setup!! Keep us posted!! Just reading this makes me wanna get one and I JUST finished a 383 smh..
Currently I’m running a LS7 MAF, FTP104mm lid to a Chris1313 non a/c air box and it’s a restriction with the 383. I need to do this as well so I have room to put a nitrous nozzle behind the maf. Right now it’s a little too close.
I won’t change the exhaust for now. I have 1 3/4-7/8 stepped kooks to kooks true dual 3” exhaust. If the headers create a large restriction I will most likely get some 2” made. Really I would be happy with 7 at the crank or 600+ at the tire. Basically would like the car to run like a healthy heads/cam C6 ZO6.
Nice car! What does it put down to the wheels currently with the 383? And is it an A4 or M6?
