Re: Dumb Question

Not a dumb question. But headers won't help.

Things that WILL help:
- 7-blade HD fan with a new clutch. If you still have a stock 7-blade fan, good! Check or replace the clutch.
- Flush out the engine coolant really well, including the block.
- Tune the QJ one step richer -- this has REALLY helped with Eddy carbs on my big blocks.
- Check for vacuum leaks which will make an engine run lean.
- Advance timing a few more degrees, but don't let it ping.
- New 4-row radiator. It if was 30% blocked, rodding is only a temporary fix. Make sure fins are straight and not blocked.
- Make sure the shroud is good and fan blades are 3/4 recessed (blades covered) in it front to back.
