I think it is cast. As for performance, It really made more up top around 4500 or so. I went from a 4.3 to a 5.7 and put the tbi on when the engine went in. I decided i wanted more power(doesn't everyone), so the buildup of a 383 began. With a big cam and AFR heads i dont think this would cut it so i removed it to sell for money to fund a tpi/super ram swap. I also have a Holley TBi intake that has 2" bores and works great with the TBI. I haven't listed it yet because I have nothing to replace it with. If i dont sell the TBI soon, I will wait and sell the intake,Tbi, and a helix power tower w/ 2" bores as a combo deal for around $400-450 or so, haven't decided yet. I paid around $620 for it all 6 months ago!
