I have a '68 Satellite, currently a 360 motor, building a 451, 99% street machine, going for best street handling.
Last year while upgrading to new Eddy IAS shocks all around, Magnum Force drop spindles, new Hotchkis rear leafs and shackles, new stock strut rods, Hotchkis UCA, boxed LCA's, and Hotchkis front sway bar, I upgraded my torsion bars in my '68 Satellite from the stock .088" to new .092" from Mancini. They are OK, but I wish they were a little firmer. Now I have a new motor in the works to replace my 360 - a 451 stroker. Given that I think my 360 would benefit in handling from the next size up - .096" torsion bars, do you think that with the 451 I should go with 1.00" torsion bars or are the .096" bars good enough?
One reason I ask is that currently it feels like my car has some understeer (possibly from drop spindles and front sway bar?) and I know that too big torsion bars can also cause some understeer. The caster was dialed in at +4 by the alignment shop.
The other reason, is that Mancini doesn't carry any larger than .096.
Do you have an opinion on where to source the torsion bars from for ease of install and/or performance? I've listed below what I've learned on the forums regarding several suppliers. Feel free to chime in if I have some wrong info.
Mancini - largest size offered is .096"
Global West - love my subframe connectors, but I don't see torsion bars on their website
Just Suspension - offers 1.00" bars, have heard good things
Hotchkis - offers 1.03" bars, have heard good things, but may be a bit stiff for my car and with the drop spindles and beefy Hotchkis sway bar?
Firm Feel - offers 1.00" bars. Have read from several forum members that they had trouble during installation due to longer hex heads on bar ends.
PST - Have read from several forum members that difference in hex end clocking compared to stock (which is ~ 30 deg) caused installation problems
Right now I'm leaning towards either Just Suspension 1.00" , Hotchkis 1.03" or the .096" from Mancini. What say all of you?
