I put mine on a rear wheel dyno and it gave 186 rwhp at 4200 RPM and 285 lbs of torque at 2??? rpm.

The modification that the engine have is no cats, no emission stuff, recurve distributor and stock carb rejetted.

Rear wheel hp on a bone stock L48 from the factory would be 150-160. Assuming mileage, may be a little lower.

I had similar rear wheel perf with 195rwhp and about 325ft lbs torque after rebuild that included cam, intake, distributor recurve, duals (no cat). Have since added heads, headers, new duals, richened carb settings. Much better :smash:
