I think alot of guys build more motor than the car or combo can work with and then are disappointed with the results. The motor in my old Duster could probably be reproduced for well under 5K and in a #3230 race weight car it went 10.60's at 125. Bob George can attest to the fact that the Arrow motor is very basic also and came in well under 10K. Granted the Arrow is light but it's running 5.50's in the 1/8th with time in the stop. Build smarter not with more $$$ is my motto. That and I'm cheap..
