Re: Original OEM ZL1 427cid numbers matching
Hiya,
That dyno sheet looks more accurate. Shoot, that engine could be worth some mega-bucks to the right person.

Re: Willys Flathead Idle Timing
All cool(BTW, I am very familiar with the Holley stuff as well as many aftermarket and OEM ecu's) Ok, another little tip to aid in idle control tuning after adjusting tables to get highest map reading. Watch the IAC counts, as you get even closer on the tune in these areas(timing and fuel), the IAC ...

Re: Willys Flathead Idle Timing
Hiya's :) Engine Control Module: Holley Dominator (Holley Part No: 554-114) Distributor: Autolite PN: IAT 4206 1K modified to accept hall effect camshaft and crankshaft position sensors Isn't this locked out so ECU controls timing once base and rotor phasing is correct? If not, why not? Then you can...

Re: Willys Flathead Idle Timing
I bet you end up in the 2's or high 1's at idle. You can leave the timing up, headers run cooler. Get happy means you are pulling more vacuum, MAP KPA number will lower numerically as vacuum increases. Setting the closed loop learn to 0 or 5% will show you trends as to whether it is lying or not.

Re: Willys Flathead Idle Timing
Hiya's,
7 lbs/hour is wayyyyyy too much fuel for that engine at idle, probably at least 2x. Forget the wideband for now and use the MAP sensor reading as a vacuum gauge of sorts, keep pulling fuel in those cells 'till it gets happy.

Re: Rod bearing clearance
Hiya Dave, The rods do stretch, my old school blown 11,000 rpm BBC had ~.090" piston to head and you could barely see the very minimal contact. A lot better Alum rods out there now(this was in '94) They do shrink from work hardening. I can't advise on clearances for that stroker as I've not don...

Re: Anyone know of a source of springs for distributors
Hello,
When I worked at Mallory back in the 80's, I sort of remember most or all coming from Century Spring.

Hello,
Disagree. Round off the outside edges of the big end and narrow the small end within reason or change pins. Tapered pin is lighter and stronger.

Re: No more King XP bearings
Hiya,
Unless you are running Nitro, use the standard allecular AP and let them move. Check and set clearances and go
King bearings for the win.
