LA 340 Intake Manifold

When setting up your engine, do the math and find a calculator to keep a pump gas friendly ratio that suites your local octane limits. IDK if 93 is available to you. The small TF changers can raise the compression up real quick.

The above can be done in a Magnum 5.9 for quicker results in a pump gas friendly ratio. As the Magnums are a 9.0-1 to start with.

If you don’t mind throwing bags of money at a stroker, that’s your call and I’d run right to a 4.00 crank and not look back. You could increase the cam duration by 6*’s without batting an eye & have no ill effects. Though if you you change your gear to a 4.10, then a cam can jump in duration like crazy, but be reminded the bigger the cam the higher the operating rpm is.
