O.k. I decided on the combo I think for the new motor, it'll be a dart 4.125 bore block and a 4" stroke for 427C.I. Anyway I got a smokin deal on a set of brand new afr 205 heads that have been professionally ported and polished, ferrera exhaust valves, titanium retainers and .740 lift solid roller springs, brand new. The guy that had them couldn't get them to flow enough. He was gonna use them to try and make 1000 horsepower with boost. I'll be getting the flow charts with them, but anyway, now this thing should be capable of 550-600 hp with a custom cam and a well designed combo. It's a 100% street car that is just a toy and I just want to make it fast because I can and tough so I don't break it right away. So it will have to be streetable and I don't want to cage it. The frames, floors and torque boxes are all solid and straight, I have a monte carlo bar and one piece export brace in it, but will a set of maier or likewise subframe connectors welded in be enough to keep the body from twisting? Shouldn't ever see and really hard lauches I don't think, as it'll probably have street tires or drag raidals on it. What do you guys think?
