My plans for the hood are to cut along the cowl sides and raise the factory hood...
No DYNO pulls yet.. waiting for nice warm weather... I only have 6 miles on the engine.. I always wait 1500 miles for all my breakins.. Need to complete my tuning
Then HP torque pulls

That motor sounds like a screamer, I watched the other video. Sick! If you go to Bellmore on Friday, look for 35th Anniversay.

The hood will need to be cut.. and fab in a scoop.. I want 100% benefit from my 1206 port HSR
You have shamed me into cleanliness. I even see the rug on the garage floor.

Nice job.

Installed a new TPS. Now my voltage & throttle % are normal. NO more codes;-)
My open loop table was scary lean.. ballanced that out to match the corrected closed loop.
just shy of 400 at the wheels with a terrible rich condition in closed loop & TPS not working @ dyno pulls
my clutch slipped at 5,000 - 5,200 1st pull.. 2nd pull.. lol engine hit 6100 wheels 4,000
And performance clutches are about non existent.. as per Jim @ power torque system

Sorry ran out of time this year. Car is in locked up in hibernation.. next year I'm in great shape. My hood is cut. I dialed my tune. It's awesome.. my clutch barely holds.. I was told there is a 89 - 90 aluminum bellhousing.. Then a LT5 Plate & disk, might fit? glass the hood, repaint. dyno & vid clips. Can't wait. Thanks for looking, see you after winter.

Happy 4th!!!! Welcome back sorry for the delay!! car was in storage till April 20th I perfected my tune. discovered my D44 clutches are slipping @ 58 - 60 Lbs just ordered a HD clutch plate set. I tapped my diff and installed a -6an fitting. the fluid was very bad. made a Gasket buttoned it back up. with Lucas & LS additive.
My LT4 clutch is the next replacement. it slips very bad on hard launches & 120Mph range a smoke show in the car. I looked @ the McLeod twin disk very nice!! but the belhousing, Hydraulic TOB combo about 3K... I guess I will try the Super Street Pro Combo. I wanted to do a strip time. I discovered my low, Outer joints where wasted. removed & ordered Up, Low & outer A few Night vids todate...
Till next time!!!!!
