273 commando Build

The LD340 wont match the ports of the 920 and will hurt the power you are trying to make.
Yes , I know what you mean . But that is what the engine cam with. I do have a stock 4 barrel intake that I could modify if need be. At least it would have the same ports.
DOES ANYONE WHAT TO DO A TRADE/SWAP FOR A LD4B INTAKE ??

I remember reading an article about a 273 running the stock intake and it was making some good HP.
