if i build a 393 stroker with all scat parts and keep it fuel injection what kinda of power can i exspect going to have aluminum heads and all probly going with the trick flow type r intake probly 75 mm tb unless i need bigger and idk about the cam tho this motor is going to be n/a any guess on hp and any ideas on this build

 

Well power levels are engine specific and more than that combo specific!

What H/C/I compression etc......

The box r would suit your induction needs better on that cuin than the r pending everything else, you can use a regular r and 75mm tb n/a and prolly break 375rwhp just depends!

 

looking for probly 10:5:1 compersion heads idk yet but they will be aluminum thats why i was asking for ideas id like to make over 400 whp on a na and i thought the box r is for boosted cars not na?

 

There is no app specific printing anywhere on it its says ideal for boosted and nitrous apps i do believe!

393 with 10.5c/r you will be there with around a 61cc chamber and flat-tops!

Use atleast a 185cc head and you will be on your way! Just get the correct vlv sizing or close to it and the right cam and intake and you will be where you want to be!

I know with a set of vic jrs an xfi custom ground on a 110 lobe sep will be quite the n/a beast using either the vic efi or the r series with a 75mm tb, use the box r if you plan on anything bigger than a 75mm tb!

I have witnessed this combo and it was quite a monster.
