Front suspension advice needed

I'm building a 28 A pickup with a 454 BBC, and I want to have my axle out in front of the grille, but have my spring or springs hidden. I figured the easiest way would be to use a quarter elliptical set up like on the Posies Thunder Road Truck, but I do have concerns about handling at high rates of speed. I read somewhere a while back about QE's being notorious for having a shake at speeds over 100 mph. Does anybody have first hand knowledge of the handling characteristics of the QE's? Would anybody recommend using split bones with a traditional transverse spring mounted to the bones over the QE's?
Thanks!

hey fellow NS guy, i live out in BC now but i grew up down on the south shore near Bridgewater, theres lots of guys on here would say not to run split bones at all, they get stressed in ways they were never designed to be stressed and have been knows to snap off, lots of guys will disagre and say there fine, i`m building a 28 chevy with the axle out front with a transvers spring and hairpins, i cant think QE's would make any difference to handling as long as you controll the axles side to side movement and run good shocks.

 

Hey man, that's killer to come across an East Coaster on here. Thanks for the reply. The big reason why I'm stuck on the QE's is for ease of set up.

I want to channel my body and keep the original hood and grille proportions in tact. With that in mind, space near the rad and front crossmember is a big concern with using the BBC.

I read something on here a while back saying "good luck going over 60 mph with a quarter elliptical set up". hahah, just want some feedback on the general feeling of using the QE's for high speed apps.

Keep in touch man,
I'd love to see some pics of your 28!

ever consider putting the spring inside the front crossmemeber? ive seen where they have cut the bottom of the sqaure tube and left the end open, and ive also seen where they have used the more flat spring and didnt cut on the crossmember. older frames use to do this same thing.

 

If everything is designed and aligned correctly,including decent shocks,
there is no reason 1/4 elliptic springs won't do everything you want.

Split bones cause an I-beam axle to twist slightly as the body rolls.
NOT a problem.

Where people run into problems is with tube axles,because they don't want to twist.This is especially important on the rear axle.

 

running qe's with split wishbones , friction shocks, pannard bar, radials, 136 wb on home built frame, runs 85mph in rain or shine without a moments discomfort. will build the next on with qe's all the way around.
