Let me start out with the respect factor for ya. I've noticed alot of you have tons of motor experience and know the costs vs. the ins and outs of all that can go into building motors and all the options. Well that's what I don't have. So here's the cars background and current set up. I bought a 72 dart swinger that the previous owner raced at a 1/8 mile track with a 360 in it and 5.13 gears. My plan is to yes, be a somewhat trailer queen to some shows, take out on the weekend, but mainly to get into some bracket racing. I mini-tubbed it, cut down the rear and changed the gears to 4.10 for 1/4 mile and some street. I have super stock springs in now (may go coil over in a few years). I have an 8pt cage in already, and am putting the subframe connectors in next week. Dilemma is.... I have a 440 block that I need to have a magna flux done on to see if it's ok, and if it is don't know how much I'm realistically looking at to buildup a 496. I already tossed the old iron heads (anchors) so I would need everything not just the short block work. ORRRRR my 360 that is currently in the car, I don't know much about. Has a 284/484 purple shaft cam, but not sure what pistons. Has Iron heads so I imagine it's stock. Someone I know offered me the Nitrous Big Shot plate system adjustable to 300hp now set up for 225. It was only used 2 times on the street. It's the bottle heater, msd spank retard box, stainless lines, bottle, and gauge for $500. Can/should I install this NOS kit on my current set up and just add an electric fuel pump etc. figuring total $1000 till its all said and done with the added fuel pump cost, filters etc. Or should I scrap that plan and just put the $1000 away and keep saving for the 496 deal? Should I start juicin for the extra hp or just keep waitin and dreamin? ThanX in advance for any help....
