More power from my inline 6

[TJ's Chevy]

Floored to keep at 60? How steep is the hill?

What is your initial timing set at?

What's your tire size and gearing?

Couple fairly cheap upgrades would be an HEI and a 2 barrel carb. I would start with bumping to timing to 10 or 12 initial. Many times people are not getting the full benefit of power due to the timing being retarded so much. Heck I had my 292 at 16 initial but back it to 12 to stay safe. haha I would start with advancing the timing.

The one barrel is small and only good for low end power anyway. The Ultimate thing to do would be an offy 4 barrel intake with a modded holley 4 barrel carb converted to a 3 barrel and headers. Your mileage would increase and so would the power. But you'd be looking at a good $500.
