I have a '85 olds cutlass I have totally redid the rear suspension except sway bar (tubular uppers, boxed lowers, new springs axle housing bushings, isolators and adjustable shocks).

My question is that i am going to put a estimated at 450+ small block in there and I was wondering if the suspension should have like a trick racing springs or if my combo will keep the rubber to the road? Oh yeah I want to run a trans brake

PS, 4.10 and d.o.t legal drag tires
