a Hot Mod nova is almost 100% bone stock, even onthe dyno the Hot Mod motor made no more power then stock... There are many different ways to skin a cat, as there there are ways to mod a motor... Most modders limit their work to the basic flow mods with some minor timing added to the crank... And for the $$$ they charge they are supplying a good product.. I specialize in some more in depth engine mods, and spend upwards of 15 hours on one motor... I do alot more then cut some pretty grooves on the sleeve, i actualy go and re-map the engines timing and port shape with a goal of making the absolute most powerful engine possible....I can do a typical race mod like all the other modders, but i much prefer to aim towards the HP junkies and people who want the baddest fastet motor possible... My prices also reflect the level and amount of work i do, as i charge quite a bit more then the typical modder, and I do a very limited number of engines.....if you wish to see some of my work PM me and I can arrange to send you some pics.... If your after all out power, i likely can deliver what others may not be able too.
