FE Technical Forum / 1966 Cyclone Z bar question
« on: June 24, 2026, 03:36:45 PM »
I removed the equalizer bar from my 1966 Cyclone 390 car. The width is spring loaded and adjustable. The frame side has a .990 ball and the block side has a .630 ball. I'm hoping some of the Fairlane and Comet members can tell me if this is correct for the car. The listed reproduction at Auto Krafters is not adjustable. The site doesn't like my photo extension for some reason. Any insights will be appreciated. Thanks, Chuck

FE Technical Forum / Toploader questions
« on: May 31, 2026, 12:10:37 PM »
I have a RUG M3 wide ratio from a 1969 Mustang/Cougar 390 that I need to go through. Casting date on the C8 main case is 02/06/1969. I've looked on David Kee's site and have the book he sells. The question is, would this transmission have type 3 or type 4 detents and springs? Second question, are the 1 and 2, and 3 and 4 shift rails the same or slightly different? The problem I'm trying to fix is, it really doesn't want up shift into 3rd gear but will. But it will not downshift from 3rd into 2nd gear. Any input will be appreciated. Chuck

FE Technical Forum / sub-frame connectors for 1966 Cyclone
« on: April 27, 2026, 03:19:32 PM »
Does anyone have experience with sub-frame connectors for 66/67 Comet/Fairlane? What works well for under the floor connectors. My primary concern is not bending the car if it ever hooks up. Thanks in advance. Chuck

FE Technical Forum / Truck headers for Dyno
« on: April 14, 2026, 02:30:51 PM »
My in car headers won't clear the Dyno frame. I know Jay tested truck headers in his book. What should I be looking to buy? 1966-1976 F-100 352-390? I would appreciate some info as the engine is already on the Dyno. Thanks, Chuck

How much total mechanical advance (no vacuum advance) usually turns out to be optimal with TFS heads on a 462 or similar build. Thanks, Chuck

FE Technical Forum / Modifying solid roller lifter
« on: February 16, 2026, 02:22:11 PM »
I checked oil pressure today (80PSI) and confirmed the lifters are not sending oil to the pushrods (oiling through pushrods). BAM lifters, and others, have suggested using a Dremel tool to create a path between the large and small oil holes. I know I can't do that consistently. I'm going to try to convince my machinist do do the job precisely. How to do it and how much to cut is the question. BAM sent me a link to a guy in Australia cutting them .080" wide and .002 deep using, what I think is, an end mill. DART has a Tech page suggesting using a .080 radius (not sure what that means) and .020" deep. It seems to me that those three methods would yield significantly different oil flow to the pushrods. I need enough top end oiling but do not want to flood the top end.
Any insights, ideas, suggestions, or experiences would very helpful. Thanks, Chuck (S)

FE Technical Forum / Cooling system that works in traffic
« on: February 12, 2026, 01:23:06 PM »
I'm doing some advance planning regarding cooling. What is everyone using for aggressive street car that works well? Car is 1966 Cyclone, 462, TFS heads, 10.4:1,RPM intake, solid roller cam. Is there anything that work in a near OEM radiator size (the car is too nice to cut on). Two row double pass, 3 row, electric fan(s), custom shroud, etc. All input is appreciated. Chuck (S)

FE Technical Forum / 3/8" pushrods
« on: February 04, 2026, 10:01:35 AM »
I'm ready to order pushrods and I want to order 3/8". Block deck is 10.150" and square, heads are TFS un-milled, HS rockers (ball and ball oil through pushrod), BAM solid roller lifters, intake is ED RPM. The pushrod hole in the intake is .625" which leaves .125 in all directions with a 3/8" pushrod. I think the pushrods will clear the intake. However, I'd really appreciate those with a similar build to share your experience using 3/8 pushrods.

I'd also like input on wall thickness for the 3/8" pushrods as well as input on the oil hole size in the pushrod (restricted or not). My instincts are saying not to restrict but I'd like your input on the question.
Thanks, Chuck (S)

FE Technical Forum / HS rockers
« on: February 01, 2026, 03:02:43 PM »
In the instructions it says lateral clearance should be ".008-.012 bolt to bolt". Does that mean move every thing in one direction until against the stand, then measure at the stand in the other direction?
Am I correct in assuming that HS has shims of various thickness' to get proper clearance and to align roller wheel with valve stem tip?
Thanks, Chuck (S)

FE Technical Forum / Subframe connectors
« on: October 27, 2025, 01:45:39 PM »
I am considering installing subframe connectors on my 1966 Cyclone. Am I correct in assuming they are the same as for 1966 Fairlane? I am looking at weld on, not through the floor, connectors. What are some of you using that you like, fit well, and work? Thanks, Chuck (S)

FE Technical Forum / Head gaskets
« on: October 22, 2025, 03:16:46 PM »
462 with TFS heads, about 10.3:1 SCR. Is there an appropriate gasket, .030-.041 thick compressed, block bore will be +.030, that minimizes gasket volume? How much larger than the block bore size does the gasket bore need to be? Thanks, Chuck (S)
