Kracee 1

hey i just got this car in pieces and dont know if theres something i should improve to better suit my application. my friend and i just built the motor or put it together and there where flat top speed pro pistons and rings teflon coated with valve reliefs, forged rods and crank, holley systemax II kit ported heads and intake,bbk 70mm throttle body and spacer,73mm mas air c&L,24lb injectors with fmu,high flow water pump,double roller timing chain,new stock flywheel,new stock harmonic balancer,electric fans,tremec transmission,3.73 gears with rebuilt posi unit,powerdyne 9psi supercharger with power pipe, accel coil pack, subframe connectors bbk,upper and lowr control arms bbk, lowering springs, spec stage 2 clutch and think that is about it. it used to have a msd btm but they stole it and the guage pod from the car before i purchased it. what do i need to improve this or whats wrong with this combo? thanks

sounds like a nice setup. i hear holley intakes are good for blower apps. only thing id change is a bigger maf and injectors. get some 42lbers

hey do i keep the fmu or toss it. when i get the 42lb injectors and bigger mass should i get a fuel pressure regulator? this is where im stuck.

Suspect

some will tell u to keep it, but its up to u. u can do away with it. i hear kirban has a nice fpr. also might wanna run a 255 fp in tank.

you dont need an fmu with the 42# injectors, and def. get an adjustable fuel pressure
regulator you'll really need it w/o an fmu, and gap your plugs at about .35
you'll need a bigger intank pump and an inline pump also
that'll be a damn nice set up when you get it done

that engine was balanced right? Also i agree you need a 255 fuel pump since you have the SC on the car. Whats the CID?

Kracee 1

the engine was balanced buy a speed shop called dick heralls and i do have a 255lph fuel pump fogot to add that it a bbk the motor is a 306 cid.

The only thing I would have done different is the pistons flat tops are hurtin for supercharged engines, well I guess it depends on what CC the heads are as well but they say you don't want to go over 9:1 Comp Ratio I will be bang on at 9:1 with my 60 cc edels and -8cc edebrocks. I would recomend the JE -18cc forged pistons.... they are amazing

If it were me...

I'd switch to a dished piston for 8.5-9.0:1. I wouldn't waste money on forged crank or rods in a stock block. Holley heads aren't the best design (I'd switch to Trick Flow or AFR if you can afford it). I'd match the TB to the intake opening (75mm). I'd run a bigger meter and not a C&L (I'd buy a 80mm Pro-M). I'd run 42s and scrap the FMU. If buying new, I'd get a Novi 1k or Vortech SC before a Powerdyne. I'd run a Stage 3 Spec clutch.

...but that's just me.
