I remember talking to Ivo about this kit. He told me he tried building one when they were originally issued. He said it didn't take him long to realize that building the real car was much easier. He said "my paws were just too big for all those little parts".
I'm currently working on this kit and I must say I was really disappointed when I started looking at the parts. As mentioned earlier, the chassis is totally wrong as are the valve covers. There are various other little "flaws" I have found that will need improvement. This kit is a great reason to have a parts box from older kits. I dug through my stuff and found a lot of parts that will make this kit work. I have replaced the transmission tunnel, just waiting for the putty to dry.
I wanted to build this thing right, as I was a Lee Shepherd fan when I was little. You could get by building it as is, and it should look good enough. Building it the right way will just take a little longer.
When I used to work with Brent Fanning on his Nitro Funny Car & our Top Fuelers, he ran what was called a "Scott Pump". It was a smaller pump that was in fact run off of a pully which allowed it to be lower in the car. I can't really remember the theory behind the pump, but that's what we ran. None of the cars ever really set the world on fire - it was basically a match race tune-up. The best the Funny Car ran with that pump was something like low 5.20's at 288 MPH back at the 1998 NHRA Topeka Race.
I believe the last time I was at Model Empire (West Allis, WI), I'm pretty sure I saw a sheet of them for sale. That is where I got my mine years ago - and for the life of me, I have no idea where I put them. Model Empire has a website I'm sure you can find on Google.
