Hey I was thinking about buying the gt-40 crate engine for my 1990 Mustang 5.0 LX with AUTOMATIC tranny...its rebuilt with shift kit and custom2400 stall converter so u know. Has ANYONE bought this crate engine...i think i want the next up from the cheapest one...its 315 HP i think? has anyone bought this and installed it by themselves.. I don't have really any experiance with an engine swap. but this seems somewhat easy.... What total modifications would i have to do if this engine drops right in...i know i gotta slap an intake on there...and headers...is there anytign else..waht about my computer and all the sensor hook ups and all the electrical ****...does everything fit all together stock? And the price of this is about 3195 i believe...ive seen it at one site for 2995...anyone know where i can get it for cheaper..and a good reliable site to get it from...thanks!
