I am putting a turbo on a carborated 13b it is a holly 390 4.b. and i'm tring to find the best way to plum it.

 

Paxton makes a blower for carbs that uses a pressurized box. You might want to call them and see if you can buy the box by itself.

 

i have built many holley 4150 series carbed turbo/supercharger set-up's... all v8's but, the same theories apply. this is a very exclusive field for high boost applications. under 8-10 psi the carb does not require many mods but, over 12 psi fuel delivery through the metering plates and boosters as well as proper signal stregnth at the boosters become a huge issue for the novice carb tuner. pm me for more info. thanks, ron.

 

I have made 615 rwhp blowing through a holley 750 DP with very good results. The pressure plenum hat is available from Turbonetics and also K&N.
