0.88 for 383 cars

0.94 or 0.92 for hemi/hd , I’ve read both, someone will correct me if I’m wrong.

As far as recommendations, I have a 68 GTX with the factory hd bars, tubular upper control arms for more caster which is really needed, boxed lower control arms, Bilstien shocks, and a steer and gear stage 2 box. The car is nice and firm, handles great with being too firm

have i believe seen on line bars as big as 1 inch plus or is that to much?

My 67 383 came with 0.92 bars - HD suspension for trailer tow pkg. I recently changed them for new 1.03 bars from PST. Pretty happy with the ride. Stiffer, but not harsh IMO

The PST 1.03” bars are a great bar for all around use. A bit firmer than the 440/426 bars but not harsh or uncomfortable at all. Also PST offers discounts to forum members.

That I don’t know, a couple people have posted on the thread. I’m happy with my factory bars so I don’t plan on changing

My ‘68 383/auto Bee with factory air came with .90 bars.

As stated, the 1.03 bars from PST are a decent upgrade but you'll need good shocks too. The Bilstein RCDs are an excellent option.
DO NOT use KYBs. They are an inferior design that gives a harsh ride with bigger torsion bars.
If you doubt that, do some searches on KYB shocks in Mopars.

Had KYB with 1.03 bars,gave the KYBs away to a 66 Newport! I like the bars.

My rr 383 rides from factory going over bumps is like riding on rails a lot of clunking going on new front suspension shocks all around rear leaf springs (hemi springs) could be the good old classic ride from way back don't know since we are spoiled with the new car ride. Getting ready for the hemi a lot of weight will concentrate on shocks just wanted some input about staying with big block bars or go up to the larger because of the extra weight. Current shocks all around are the standard 69 napa shocks (not impressed) desperate to improve my ride.
thanks all for input. IS there a difference with front suspension from small block and big block cars???? My car just does not seem to be using the suspension as it should just ROUGH.

I have the 1.03 bars as well and I’m happy with them (and have a small block). I’m not trying to make my car cushy. I wonder sometimes if back in the day they purposely made the cars drive as “smooth” as they could.
I test drove several motorhomes before buying one and noticed one big (to me) issue. Yeah they drove in a straight line well, but don’t try to go on curves at speed. I could have spent a lot of money on bigger or additional sway bars. I tried the cheap handling fix as the apparent inventor called it. The Ford chassis that most of the rv’s came with had an extra hole that the link connected to that shortened the “arms” so that it effectively stiffened the bars. My coach handles curves pretty good now, but the ride is a little bit harsh. I’ll sacrifice smooth ride for better handling.
