I have the opportunity to pick up a 455 cu in small block Ford shortblock. It has top dollar billet parts in it. I also can get a set of pro comp Cleveland heads the castings are supposivly really strong. I can send to Dr j's for porting. He claims around 400 cfm. I will put top dollar parts in them. It also comes with a heavly ported svo intake. I was thinking of going with two 4788s. Would this be a good choice for turbos for this setup? How much power can something like this make? There's no limitations for class racing. Also how much injectors to run on alky? Thanks any help or thoughts would be good. Also what ar size and would two t4 4788 or two t6 4788 work best? I'm not stuck on 4788s but don't wanna spend 5000 on two turbos. Any other suggestions? Sorry its a lot of questions but I hope I get some responses.
