trying to pull ponnies with little cash

thanks for the insite again. ive heard both from around here that getting sum ponnies out of a mopar is gona cost me alot nd that its gona be a cake walk. my intentions for this car is to make a nice show car out of it since theres not to many in my town and i want it to perfom as it looks cause this '68 318 cant break the tires loose to me it feels restricted but yet its a beast. as for headers i was thinking some flowtechs cause they are on the cheaper side and they are in coliation with holley
