I believe it is a gt-40 intake and a Holley 650 racing double pumper. A Victor Jr. was to high so they had to use a more compact ( lower ) intake. These guys were very good. They had all the correct dimensions of all the parts of the finished engine so when they finished building it was a perfect drop in without touching the glass in the rear clip. I have 1/4" clearance between the glass and the top of the K&N Extreme filter. I can't brag to much about those guys. I watched and helped a little putting it together which started on a Tuesday and was running on Thursday then completed Friday morning, road tested it and took it home that day and have been having a blast ever since with no problems since. Not bad for 4 days. They must be unbeatable changing tires in the pits. Joseph /ubbthreads/images/graemlins/smile.gif
