Well the install was pretty easy. Replaced the flexplate with the hughes SFI. So far I love it drives real good not to loose. I still have the stock 3.23 rear. I only have 100 miles so I haven't got on it off the line, however I have got on it from a 50 roll and all I can say is damn, what a difference, I have a small vibration And the cause I believe is I installed polyurethane trans mount and torque arm bushings And they are really stiff. I checked the BMR loop for clearence probs but no rubbing anywhere. So It must be the mounts, and like I say very minimal vibration only under wot at 5500+ rpms. Our first test and tune is in two weeks so I will keep you guys posted with the results.

 

Did you eliminate the codes? It bit me yesterday

 

Which codes. I haven't changed the codes yet. So far no codes.

 

Search for my post in here. Nobody told me either you have to eliminate them and some people don't get them. You may be lucky for a bit like me.

 

Must be the p0751 and p0757, Also to change lock-up. I will go tune that tonite, thanks for the info.

 

Got it all tuned. I got on it a little from a 10 roll, Its def got some *****. Spins the M/T's pretty good from a 10mph roll. I am likin it

 

The Yank converter was one of my favorite mods, other than the nitrous.

 

The shift extension is great stays at 5000+ the entire time. Actually feels a little faster in 3rd past 90 mph.

 

Good to see your liking it. I just put my ss4000 in a couple weeks ago. I love it!

 

I just got my ss3600 install yersterday also... Man what a difference!!! can't wait for the Chevy Show this weekend...

 

AS far as the vibration goes, I have read bad things about using the poly trans mount. A poly mount for the engine is ok though.

On my setup I have a poly motor mounts and stock rubber tranny mount and have no vibrations.

 

wait till you get on a preped track with that new stall...gonna put some daylight under those front tires...

 

It is a small vibration so not to concerned. I wanted the stronger mount because of the stall. I am going to check the loop tonite and drive it some more.

 

Well I changed out the poly mount tonite with another rubber one. No more vibration. Poly mounts really suck. Thanks for your help guys.

 

I thought my 4000 stall was badass. But it's like crack. I want more, lol. I'll probably jump it up to 4800 next.

 

Ha, same with nitrous.

 

Turboav let me know when you are ready.
Thanks,
Greg
