As much as I can!
Realistically will not be anywhere near 700 HP, I’m adding a set of PowerPort 240s to my engine because it needs valve guides. Cam is a 254@.050 SFT, only .520 lift. I just don’t want to give up any power with a sub par intake. Stock stroke 440 @ 10.5:1. I’m guessing this should be in the upper 500 range. I care more about how much I pick up over the Sealths I have on there now, wishing and hoping and thinking and praying it should be a 50-75 HP gain.
You should be fine with an ootb TF intake. If you want a little extra power for a little extra money then order the intake from Hughes Engines and have them deep port the intake. The Hughes deep intake porting is a good value for the buck. I assume you're using a Holley carb of some type? If so, then a merge spacer under the carb will also help make some more power as long as you have the room.
