Well, um. ive been workin on my design so much, and with fulltime school and two jobs. A very high maintenance girlfriend . I havent gotten anywere. I might drop one of em off today at the machine shop and tell em to have fun with it. I found blades for like 4 bucks a peice too. 25$ minimum i think.
Ill post again late tonight.
BTW, i also still need to go cross reference about 60 pn#'s at the dealership for injectors and other tbi related parts.
Ill get a weekend off here one of these days.

Weekend :scratches head: what's that? LOL
Man those 2" flaps take up a significant amount of surface area it seems. I put them up to my radioused TBI unit (still mounted to the car) and it just sank into my radioused tb lip. Talk about a huge difference in surface area. I was thinking of prepping mine before hand by using a 1.8 wood hole punch and drill it off center toward the center more so as to not hit the edge of the tb unit...I don't have a spare tbi unit yet on hand to test out this crazy idea but I think it will work. If a certain someone would have remembered it last weekend I could have tested that idea already

ive done much more measuring. dont go punchin or drillin on that thing. there is almost no way to bore the 1 11/16 tbi to 2" without either adding material. or having VERY thing WALLS somewhere. On exact centers, which is what ive measure from a 2" gasket, you break thru the back. im not about to just throw away 50 + machining to know. im going to test as much as i can before just doing it. i have to think of somethings. how to not have holes or cracks in the tbi after machining, since no matter what the walls are going to be very thin. I also still need to take off the 454 tbi. mon looks like a good day for that. the 2 degree weather isnt helping at all btw.
