How much power do yall think this setup will give u?

 

Ignorance is the ONLY reason to go with that combo today.

You can have your stock heads ported, get a matching cam and make as much at the wheels as the LT4 HOT package makes at the flywheel.

You only have 6 posts so obviously you are new, long as you asked before buying you are off to a good start.

The LT4 HOT package made 425 FLYWHEEL hp under ideal conditions.

Here is an example of making MORE power at the wheels with just heads and cam.

yeah go with a LE package you will be more then happy.

 

LE or AI packages. As both companies have proven themselves on the LT1 platform. Do a seach you will find TONS of stuff on both.
