choosing correct shocks

Depends on your budget,and what you expect out of them. Basic street /strip use: Competition Engineering/Koni/ Lakewood. More serious about tuning for every bit of E.T: fully adjustable shocks(QA1/AFCO). More adjustment on these,also more expensive .What rear suspension you use affects,also. If running like a CalTracs leaf spring /bar setup,Rancho RS 9000 shocks are recommended. How much do you want to spend,what do you want it to do? Listing the combination, helps here.

Probably use some mancinni xhd leaf springs. Don't need a all out race setup for my power. Gonna build a 400 to 425 horse 360. Use a good 9 inch slick with 355 gear
