Inliners International Forums General Discussion Hi Performance Chrome adds 6% across the board, road test proof

Jay,
Yes I am already assuming they ran the 292 cam grind in the 230/155, but you'd have to degree it to know for sure.

Good point on the exhaust pipe maybe Tom can check that too.
I assumed a bigger one (at least an honest 2") to try to match that road test.

It takes cam, carb, intake and exhaust (all from the 292) to get an honest 155hp out of the Gonkulator, compared to the 230/140hp which just makes near its rating.

All those parts are bigger on the 292, but you still get less than 5hp out of each one.

Gonkulator currently says

Seems instead of this being the "Chevelle Six", it should have been in Chevelle and Nova too but just with stick cars - much of its advantage would go away with the too-tall powerglide. Then again with the Chrome adding that extra torq across the board, that adds some low end back LOL.
