I measured with digital calipers, which isn't the most accurate way. But on all cylinders the height was consistently 1.950" ±.

Parts are trickling in. Contacted SST for the clutch kit and 130T neutral balance flywheel. I have an older Keisler Engineering model, 10 spline shaft. With the planned increase in hp and torque, I stepped up to the McLeod Super Street Pro clutch kit, good for up to 550 hp. The old disc was...

I'm thinking that they'll work because I was using Remflex gaskets on the magnum heads and I'm reusing the TTI headers. They fit perfect on the bench.

I measured the exhaust ports and the 6027 is the closest match. Thanks.

I use the Stage 8 locking fasteners. I hope they work with the TF's.

I have a Stinger/AAR 6 pak hood on the Coronet. It fit pretty nice right out of the box but it needed trimming on the sides. Took an afternoon of work to get it to fit right.

I bolted the TTI's up to the heads and they fit fine. I'm still debating whether to use the 6003 or 6027 gasket for LA engines, or the 6004/6028 gasket for magnum engines.

On my current build, I'm swapping in TF 190's for the stock cast iron magnum heads. With the stock heads I used a Remflex 6028 gasket with TTI headers. The middle two TF exhaust ports are shaped more square than the magnum heads, which have a slight downward dogleg. Laying the gasket across...

What's the p/n?

Greg was asking on my behalf; the front inspection cover has been missing since I bought the car. I don't want to separate the adapter from the bell. Greg has a cover in his stash from another tranny that can be manipulated to work on this one. That bell needs some heavy duty cleaning before...

I talked to Mike Beachel at B3 Racing today. What a wealth of knowledge, and one of the truly nice guys in our hobby. We talked for over an hour, starting with rocker arms and spacers, then delving into cams, ignition timing, how to solve detonation issues. Some interesting subjects came up...

I assume that was a solid roller cam? I agree with all your points. I'm more than okay with spring rates being a little heavier than lighter

I caught some discrepancies in TF's specs, depending where one looked. The 150# seat pressure was given to me by Jeff; there is no reference to seat pressure in any TF literature. I them asked him why the instructions state 138# seat pressure. He said that when the springs are installed on...

On that note, in the video Powell was referencing LS engines with way over .600 lift, revving to over 7,000.

The owner (can't remember his name) specs his builds on the tight side of the safety margin to create more spring compression.

I was watching a YT video from Powell Machining and Cams. Too much safety margin isn't good either as it creates distortion and harmonics in the spring.

I used the wrong terminology. Hughes requires .080-.095 lifter pre-load; does that affect the coil bind calculation? As I understand, .060-.120 is an acceptable coil bind safety margin.

Coil bind is 1.190"; from the 1.900" installed height leaves .710". Max cam lift is .587, leaving .123" safety margin. But how does lash affect the safety margin? The recommended lash is .080"-.095"; is lash added or subtracted from the safety margin?

I have to do a reset. Sorry for leading everyone down a dead-end path. After taking it all in, it didn't sit right with me that a head that was built specifically for hyd roller cams could have spring pressures so far removed from Hughes Engines' specs. Today I spoke with Jeff at TF and got...

My lack of experience is showing through, I appreciate the input from seasoned builders such as yourself. I do like the cam so I'll march ahead by shimming the springs.

He and I have been playing phone tag. I'm currently it, so I need to call back.

I'm not beating on it hard, the recommended 145 should be fine. I'll shim the TFs, after talking with Mike at B3.

Thank you, I get it now. I was thinking about carpenter's shims, which increase a gap. While shimming will increase the seat pressure, shouldn't it also increase spring pressure through the range of compression? It's still boiling down to two choices: remove, shim, and reinstall 16 springs...

Max lift is .680"; .093" greater than the exhaust lobe at 1.6 ratio. They do specify a large range of cams for those lifters. The cam card's open/closed pressure specs are lower than the specs for those springs, which backs up your comment about the being on the smaller side. How does the...

I've seen these on Summit, ranging from $30 to $140.

It's an off the shelf grind so I'm pretty sure Dave will let me return it. But if I replace the TF springs with springs that are .100" shorter, won't that leave a gap between the retainer and locks?

Still waiting on the machinist to finish the block, in the meantime I'm digging into the cam specs on the Hughes HR cam. Hughes requires that their spring p/n 1129 be used with these cams. Comparing these specs with the installed springs on the TF heads reveals some discrepancies. Per the cam...

That was the big takeaway from the last week; 6010 is the go-to for dirty metal. For Greg and I, we had to get through the stick welding part of the curriculum on the way to mig and tig.

The next three weeks of class will be a steady diet of MIG, then the last week we'll be introduced to TIG.

That's what our instructor said too. 6010 can weld in the wind, rain, snow, etc. Perfect for off-road repairs.
