L-72 Dyno Test

[Stefano]

Rob,
We had a local speed shop dyno test a stock exhaust but for headers on a warmed over 454 LS5 Chevelle vs a 3" inch mandrel system and it meant just over 50 rear wheel HP and 4O foot pounds of torque. Those stock systems with all the crimps and bends are very restrictive.

I installed a set of 3" mandrel bent Torque-Tec pipes with individual 13" Flow Masters on my Ohio COPO Camaro.

The exhaust fits great and sounds even better. It is a bit obnoxious and does set off car alarms on a regular basis.

The car runs a stock L72 +.030 but for L88 spec cam, MSD, Hooker 2" Super Comps. I am taking out the original BE 4.10 rear and swapping in a 4.56 set up.

I have a set of 9" M/T E/T Drag Radials mounted and ready
to go.

I will try to test the set up within the next Couple of weeks.

I just hope the Muncie trans holds up.
