i have the trick flow plate kit on my car right now. im carb'd and my kit is good for a 300 shot. was $470 i think shipped from summit. im also building an R block but the size stroker im not sure yet. was gonna do 347, now im planning it more with the machinist who has built a ton of solid rollers like ill have. planning on 7500rpm shift point, 630-ish lift, and ported RHS215s from the same machinist and 250-300 shot on a nitrous controller. aiming for the same compression. once i start gettin more parts ill post a progress thread. good luck with the car and keep us updated on the spray idea.
