Alright guys...I am open to any and all opinions, and very sorry for the long post right off the bat. Just trying to be specific in what I want. I have done a couple searches, but haven't really found what I am looking for. I have an 88 IROC w/a 305TPI and it's just too slow haha. Anyways, I am looking for a RELIABLE and streetable engine setup. I was thinking mid 12s N/A and maybe low-mid 11s on nitrous. I think going with a 355 would definitely end up requiring something too radical for what I am looking to do, so a 383 would probably be my best bet. I want to go with a hydraulic roller setup to maximize streetability. I think a 4-bolt main would be a good choice, so should I look for a late-model roller truck block w/a 4-bolt main? I found this rotating assembly on eBay, obviosuly. What do you guys think? Next would be the cam. I was browsing some of Comps cams and was lookin at the Xtreme Energy lineup. The XR276HR seemed somewhat streetable, but I'm not sure if it will give me the power I am looking to get. I didn't get to look through too many other product lines. Would you guys recommend a custom grind and if so, which company do you think? Next up...heads. I want the car to have a decent amount of low-end grunt, but I am sick of running out of power by 5000. I was hoping to rev to 6500 because I think I will be running the HSR and I want to maximize its potential. What brand and rating should I be paying attention to along with CC size? I'm not sure exactly what my C/R should be to maximize hp and yet be safe for nitrous. AFR and Dart always seem to stick out as quality heads. After that I think I'll be going with the HSR and a 58mm TB. I'd like to stick with a 700R4 for OD to cruize, and Pro-Builts 700R4 seem like a good choice. Would you guys recommend a custom converter, or would an out of the box 3000-3200 be ok? I'd probably shoot for 3.73s in the rear and some nice tires for traction. 12-bolt down the line after a couple launches and the 10 bolt blows up. I am very sorry for the long post, but I am going about this pretty much on my own because I am surrounded by a Ford crew who build nothing but Mustang engines and its time to show them what my car can do. haha I realize you guys will probably need to know a budget, but just go along with some of my suggestions and maybe give some of your own. I appreciate this so much. Sorry again for the long post!
