Was thinking of doing a budget motor in a lighweight race car for the hell of it. Does anyone have any dyno numbers on a 5.3 stock or with mods. What is the compression out of the factory with these.

for starters i know most 5.3 trucks dyno in the 220-240RWHP area stock. Deff have seen more than a few bolt on cam trucks making WELL into the 300s at the wheels through an auto.

I did 348 and dont remember the tq with a stock 5.3 in a 66 impala with a locked stock stall 4l60e.
pacesetter fbody longtubes/3in dual w/ x and flowmaster knockoffs
ported fast 78 intake
218/228 .550 112 regrind cam/ls6 yellows
car had power steering

nothing else

my buddies 62 bel air did 300 with the same regrind, stock manifolds, quiet mufflers, ls1 intake
no power steering, no a/c

mines in my sig 275hp 329tq. I didn't have an h pipe at the time of dyno though, oh and my engine has an ls1 intake. An L33 has 9.9:1 compression and LM7 9.5:1.
