Author Topic: Back-Pressure Question lky_3 ¯ Member # 1116 posted                                 I have a NA 306 running 10:1 compression with GT40P Heads lightly ported, with Long tubes and Off Road H and 2 Chamber flows dumped. Question is: Am I going to have enough backpressure for a good low end TQ? Remember...NO Cats. If not what are my options: Buy a High-Flow catted X/H. Put some High-Flows on the currnet (welded). Lose the LT's and go with shorties. opinions please. Thanks. -------------------- 89 GT Yes, Primer is a color!
