5.7 with hilborn injection

Hilborn offers an efi version for 6.1 intake ports. Here is my forged 5.7 with hilborn:



I have not been on the dyno yet. I will be within the month.

FYI- most of the high rpm drag race guys are running the drag pak intake with great success. They are running 25x/26x cams.

Also, you mentioned 'refreshening' a 5.7- are you talking building a forged bottom end or using factory components? You can't run a very big cam with factory pistons (22x/22x). I don't know if anyone has fly cut the pistons and tried to run more- most build a forged motor if they want more.

And are you talking hilborn efi or hilborn- pump style?
