Agree with all your points Ross but one sticks out to me. Sticky lifter bores. Having done long ago a number of in-car cam swaps, we noticed that the removed lifters had deposits on the lower (cam side) ends. Taking out the lifters showed similar crud inside the bores, hard to remove even with determined cleaning. We noted that some of the new lifters had trouble spinning in the bores. We went back in with lacquer thinner, acetone and even gasoline until the lifters spun easily.

Yes, if they can't spin, the lobes will go flat in a hurry.

FE Technical Forum / Re: piston skirt clearance
« on: March 18, 2024, 06:47:36 PM »
My old 390 built in the 80's has/had the TRW 2292F 0.030" pistons.
The skirt clearance was 0.009"
Ran that way for many, many hard run miles.
Had 5.14 traction lock rear - saw plenty of rpm on a daily basis - was my daily driver through university.
The 390 sat on an engine stand for 25 years - took it apart last year. The piston skirts look brand new!

Had to laugh at your .009 clearance. Long ago, a now former T.A.D. racer ran .010 in his blown Donovan 417 blocked Hemi. I questioned why so big and he said anything less would backside the piston. This btw before the Teflon buttons went in the skirts. He had boxes and boxes of damaged pistons in his trailer too, ready to be sorted out someday for a few reusable ones.

A very cool project and I feel fortunate to be on this list where I get to observe the progress and technical details.   

I wonder when - not if for sure - we'll get to the level where we could 3D print cylinder heads in aluminum, then heat treat to the required level, then off to machining.  The equipment cost is going to preclude that for a while I'm sure.  My work has a small 3D metal printer with a build envelop of 125mm ^ 3 and the est. cost is around $500,000.   Could maybe print a cylinder head for a 110CC quad  ;D

Maybe heads for model airplane engines? R/C boat engines? LOL, but man this new technology ain't cheap now is it?

so it is normal to hear some noise while turning sharp? when going straight it seems to ride better and stays very straight when you go faster.

Yes, as others here noted, it is normal. Long ago (!) we had to jimmy our '69 all drag racer off trailer and make a 90 degree turn into the garage we rented. This in a narrow Chicago alley. Yikes, if we got back from the races late (engine noise) or the car broke, we had to push that 3,200 lb. car into that tight turn. Took a real effort too. Had we swapped out the 11.5" wide slicks to a really narrow street tire, it would have been a lot easier.

Needle n seat assembly most likely stuck, clogged or leaking by the o ring .

Fekbmax nailed it. Replace all the needle/seat assemblies or get Holley o-rings. Do not use hardware store o-rings as few have the exact size or material. What happens is with age and exposure to gasoline, the rings harden and in doing so, shrink. Gas passes right by the now hard and often cracked rings, flooding the carb's well or even passing gas over the top of the fuel bowl.

Non-FE Discussion Forum / Re: 351 C valve seat and diameter question
« on: February 05, 2024, 07:00:48 AM »
Vintage road race you say. Typically, a larger valve may work to cut low end torque if not hp. Depending on the tracks you run at, if they do not have tight, slow corners where low end power is king, then the larger valve would not hurt cornering power.

Btw, tell us about the car and post some pics. We really don't often get road race engine questions here.

Amazingly fast! Scary though as with radials and a short wheelbase, if one gets the car out of shape (for about 100+ reasons) it could be lights out!

"Yeah, I find it amazing that some guys will go to so much work, and money, sticking a Mustang 11 front suspension, in a Mustang, Falcon, Fairlane, etc, to eliminate the shock towers , just to free up some room for header bolts and spark plug changes.  Not to mention that they often install it poorly, so it`s impossible to get the wheel alignment correct. Funny how the 69 & 70  Boss 302s did so well in the Trans Am series, with the stock shock tower setup, including winning the 1970 TA championship."

Agreed. Have all the Boss 302 Chassis Manual recommendations for the front suspension on my '70 Mach 1, 351W powered. 1" drop, Konis, roller perches and roller idler (not in the Manual), bigger sway bar, progressive contour coil springs, Monte Carlo brace and more. Can't believe that $7,000+ system would allow any better cornering! Oh, and all the parts cost not even a $1,000.

Clean, very clean engine and compartment.

     Looks like he might be working on the "A-DAP-TOR" to match-up the transmission bell housing to this big-boy!  :-\   If so, I'm not sure as to just how long that transmission would hold up?   ::)

     Scott.

If it's a C-6, about 1 minute warm up time and 3' down the driveway!!!!

Found a FB link about the Calliope. Hope this opens.

Jay, perhaps you could contact this fellow. Who knows, he may have spare parts or more.

Any notes on the weight savings?
