Paul I have to agree with you. The TPI intake is designed for tq output. You will build a tq monster but be low on the HP side. The two biggest stepping stones are the heads and intake. That is where its limited the most. 400 fwhp is possible but you wwon't get 400 rwhp. And if you do somehow the t5 won't last through your dyno pull. I would seriously invest in a t56. Its basically a bolt in with the exception of a couple things. I would also punch it out and do a 355 or 383 and definitely go with a tpis mini ram or a stealth ram for your intake. I wouldn't go to radical on the can. Remember tpi is MPFI not SPFI meaning on a tpi the injectors fire left bank right bank. Not in the engine firing order. You may want to do some reasearch over TGO. There are a lot of guys making good power over on the board using tpi in one variation or another
