nice to see it in line at a car show eh?
too bad about the trans issues but hopefully it was just a glitch. is it working good again now?
I think you could solve your maf issues with a rubber elbow off the throttle body going to a length of aluminized exh tubing with a slight bend to help clear the rad hose. then the maf, then a short length of tubing or an extra long length of rubber connector hose and then the air filter. the short length of tubing after the maf is to allow the air to get laminar again before hitting the maf. on some of the older maf sensors and/or throttle bodies they used a honeycomb screen affair to act as a stream straightener next to the maf. maybe you could simply install something like that?
