Suspension Upgrade Help











The Best of Corvette for Corvette Enthusiasts
4 speed with 3.70 gears
L-82 bored .030, Block not decked-engine build number 10/05/77
New JE forged Racing Pistons/rings-9:1 OEM type pistons
Afr 180 64 CC aluminum Heads
Howards Roller cam-.525/.525, Duration 219/225, LSA 110-operating range 1,500-5,600 RPM
Comp Cams 1.52 roller tipped rockers
Howards Pushrods
New Harmonic Balancer
New Oil Pump
New fuel pump
New Bearings
Felpro 1094-.015 head gasket-Total engine compression-10-10.2:1. Runs with zero issues on 89 octane...
Reused/reconditioned:
L-82 Forged Rods
L-82 Forged Crank
L-82 Intake Manifold
Reused Holley 4175 650CFM vacuum Q jet carb-been on car since 1985
Reused Dual Snorkel L-82 Cold Air intake
Goal was to keep it as much as possible an L-82 but up the HP/Torque in the mid range RPM by a lot. The engine starts and idles just like the OEM L-82 but from 2,500-5,500 RPM pulls like a freight train. HP guess 425 Gross…Total cost 6K. Can you do it cheaper? Yes-cheaper heads-iron or aluminum, flat tappet cam etc, crate engine?. No regrets
The L-82 is a great motor to build and looks like your tranny is an auto so you might want to consult with some of the cam gurus like 63mako about a better roller cam for lower RPM grunt than mine with a 4 speed and 3.70 gears.
Hope that helps!

Assuming the bottom end is all good:
AFR 180 heads-$1,600
Howards roller cam-$600
Pushrods-$110
Felpro gaskets/cam button etc-$100
Total-$2,410 Figure $2,500
You could do it for less-around $2,000-with lesser parts...
