Happy new year, I am currently on my 3rd thirdgen love these cars ever since I was a kid Bought my first when I was 19 back in 08 (90 rs tbi 700r) had it for 2 years and late at night after having it painted I hit 2 moose with it and totalled it. Next in 2011 i acquired an 85z (lg4 700r4) put a 406 in it back in May and had someone t bone me in August, so I got a 86 iroc with no engine Trans or rear end that I'm putting my 406 700r and diff in from the 85z (got it back from insurance). Sorry about the long boring backstory but I have had 2 700r's and my only real complaint is the downshift at wot I'm looking for part numbers or links to summit racing, jegs, eBay ect to whatever I need to stop the downshifting. Not really interested in putting screws in the throttle valve.

 

What downshifting are you talking about? The 4-3? If so, plugging the TV valve is probably the only/best way.
Dang hitting two moose huh? We don't have to many of those in MN.

 

So you would rather spend $40.00 - $60.00 than a $1.00 or two.......
