This kit will add a solid 25HP Increase and the pistons will last MUCH longer than your OEM pistons (which are prone to collapse)

Reliability is our #1 concern and is not compromised in any way. in fact, this kit is MORE reliable than your OEM configuration.

A fuel control box is needed for the CFI Engines. We can supply the Box is you do not already have one.

We require your OEM head to be sent in for the conversion
