Speaking of LS rectangle ports, the LS7 heads aren't as-cast. Factory CNC'd.
Worth noting the valve sizes, 2.2 and 1.6. Titanium valves. They also sit atop a 4.125 bore and 4.00 stroke, why does that sound so familiar? Also worth noting that the 5.3 (325 CID) has a bore of just 3.780 inches. And they LOVE sticking turbos on them. Our tree fiddy is 3.875. |

Mini me heads.
The AFR LS3 260 heads would be interesting dyno comparison on the engine in post 1. The AFR's have a substantially better intake flow curve, a sliver less exhaust flow. Image of Trick Flow GenX 245 , cathedral ports. Last edited by pastry_chef; 12-01-2021 at 02:41 AM. |

with anything and it'll fail. If someone's going to spend money on a 350P, I'd rather see some moderate boost than a 4.25 stroke. 7 PSI. No intercooler. Low RPM. Slap a 8-71 on an LS4 and let me know how it works out? |

..... and sometimes have the balancer fly off and go through folks skulls causing lifetime injuries and sometimes death. Please figure that cost into the purchase of the $500 5.3 and report back. |

Mast.. Rolls Royce of the LS world.
If I was looking for 700 to 800 HP on pump gas.. I'd probably look to the Dart 280 LS3. Many great options. https://www.lingenfelter.com/product...l#.YaeRXlBOmUk |

I personally know of SEVERAL harmonic balancers that failed and took out the Hood, fender, radiator or all 3. They were Traditional Pontiac parts, not the LS parts you posted about. Bill Klausing, again a die hard Pontiac Guy, who is about 6'11" tall would not be happy if you implied he was lying, Paul. His balancer was one of the failures. Tom V.

Engineering says you include ALL of the Data, not just data that you want to use to support YOUR position.
Never said YOU were Lying. By not admitting that Pontiacs had the same issues is basically the same though. You Are just stirring the Chit here Paul. I expected you to be more of a Neutral Person. Willing to hear data from both sides. But now you are turning the discussion into a urination contest like all of the other ones on this board. I am done here on this thread. HAHA the car was out of balance due to Bills weight and obviously that caused the part to fail, NOT. TV
