Neither. Like crane. Aluminum to steel.

Have some on my 408. No problems at all. Mine are the 1.6. Been buzzed to 7000 many times. About 7 years now.

Does anyone have or make an extra wide thrust bearing for a 340?

I did nothing to the idle circuit. It didn’t go up much 13.8 to 14. When it warms up the idle goes up about 100 rpm or so. I think I was reading the gauge a little early at first.

Thanks everyone. I’m getting closer. I ordered some air bleed jets. I did change my jets. Went down to 74 in front and 84 in back. So down 6 all together. New readings are idle 14.0, cruise 13.9, tip in 12.0 and WOT is 12.7. I created one problem. I wasn’t driving far enough on my test drives...

Timing is 22 initial and 34 total and 50 at cruise. HSAB are .032. Total timing is at about 3000. Emulsions are .026 top, .026 bottom and the middle is blocked. Jets are 78 and 86. Air bleeds, channel restrictors , emulsion jets are all replaceable. Thanks everyone.

I just installed an aft gauge in my dart. Engine is a 408 9.8 comp. 254 260 at .050 cam on a 108 in at 104. Speedmaster heads, torker2 intake and a pro form 850 do carb. Readings at idle are 13.8. Tip in goes to 10.9 then about 12.5. Cruise is about 12.8. WOT is at 12.0. When I accelerate from...

Speed pro h116cp are duplicate weight. They should give you about 9.5 to 1 with stock type heads. Just food for thought. Mine were within 7 grams of the stock pistons so I didn’t balance. Engine ran smooth. The ex 268 is a great street cam.

I had a Cuda with an 8.5 comp 440. It had a small single plane and headers, stock roadrunner converter, 3.23s and a mp 284 cam. Car ran like a bat out of hell. Bottom end was great. 2000 to 5500 was really strong. For a daily driver the cam you have will work fine. I wouldn’t be afraid to use a...

My Doug’s fit very well and no more crushed tubes.

I like 3.55s the best. 28 inch tires on the street and 26 for the track. You can definitely feel the difference between the two.

Every stock engine I’ve tore down had the aluminum bushing.

I’ve heard nothing but good things about Ultimate converters.

I use NGK heat range 6 with 100 shot of nitrous or n/a. Plugs are always clean. If I go to a 150 shot I change to a number 7 non extended tip. Never had a bad NGK.

When I was young and broke, I would put used lifters on a new cam. Never lost a cam. No break in either. Start and idle then go. What the hell has changed so much.
