Im looking at the one for sale on the board. would the intake be to large and hurt performance on a 3.8. my engine combo is all forged lower end,stage1,alumn heads,45a or 70 turbo, around 214 or 218 roller,not sure on the cam. Would a fast TSM engine gain from the intake if the rules allowed it???? I think the HP will be 650-750. Would a ported lower and PTE upper be better. Im starting from scratch and have no upper end parts.
