LQ4 into a 3rd Gen/1972 Nova by frojoe

3 minute(s) of a 891 minute read

I actually like the rear half of a Nova waaaay more than the front. The muscle line from the top of the door extending back and humping over the rear quarter looks cool, I think.

Andrew is being a huge help and highlighting "areas for improvement" in my tune. The part throttle N/A are of my target AFR was off, and although my car idled quite well, he's suggesting I revamp my IAC parameters to make the Holley ECU control the idle better (or period.. haha).

After having probably 4hrs of seat time in the car between Sunday and Tuesday, the softer rear springs definitely evened out the ride quality. I still need to stiffen the front up to raise it 1/4" to 3/8" to get rid of rubbing, but overall the driving situation is quite good. The shift **** is EXACTLY where I want it, and the modified springs in the shifter and reverse lockout solenoid feel great.

So far I need to (in order of importance):

- dial in the tune
- measure and dial in front alignment, specifically toe
- stiffen/raise front end
- rebuild steering column to take out slop in the tilt mechanism
- FABRICATE FRONT SWAYBAR (now that my focus isn't on extreme stiffness of rear springs, front can be paid more attention)
- new/tuned steering box to eliminate some slop and bring some more road feel back into the equation
- new coilovers with more adjustability all round (very long term project, but I want to hack up my subframe to accept a more conventional-length coilover)

A completely unrelated update relative to tuning, but since I was driving the car around a bunch working on part throttle and beginning of boost fuel map, I thought: why not get some scientific footage as well?

I also tried taking some whoooshy videos but the wind noise was too much to record properly.
