thanks for the info - i'm hoping to reduce some cost by picking up a rollover with a 5.7 or 6.1 hemi in it and just megasquirting it. The reson I'm askin is i would like to do a build so i can have fun at the local autoX because whats the fun in having these cars and not driving them lol! weight is the biggest issue and so dropping in a alterkation will help reduce weight as well as gain a huge improvement on handling! Also dropping in a 5.7 with fuel injection will be ideal for what i want to do - thanks for the links - i'd be very interested in seeing your progress once you get the 6.1!
