Terrific(!) the information in the link you provided sounds like the path to properly correct my problem. I will look into the A+A parts necessary to make the shift point modifications. Thanks for the link! Steve weim55 Colorado

It’s adjusted according to the factory service manual. I’ve also checked the throttle valve to make sure it’s reaching it’s full travel at wide open throttle so I don’t have any reason to think it’s an external issue. Either something inside of the transmission is not allowing the throttle valve...

An issue that I have on my 62 300 Sport w/ 727: Full throttle up shifts are way too early. I don’t have a tachometer on the car, but I’m guessing the upshift RPM is under 4000 RPM. Have checked every portion of the linkage for proper operation and adjustment, it’s working as it should. It will...

Nicks Garage test of the 300J cross ram 413 is the best I have ever seen with that induction set up. Yes, MONSTER mid range torque from that 413. EXACTLY what it was engineered to accomplish! Horsepower fell off dramatically @ high RPM (4500rpm+ if I remember correctly) , But that would not have...

I have never driven or worked on a 300H so its performance is a bit of a guess on my part. Using a bar for something I do have experience with: Overall performance similar to a stock well tuned 383 automatic 68-70 Road Runner would suit me fine. That’s actually a pretty high bar for that 440 in...

Digging a little deeper, I found an Icon flat top w/ highest CH so far @ 2.067, Part# IC968. 9.9CR w/ .017 gaskets and 90cc head chamber. This weekend I will measure head chamber volume and the compression height of the current pistons. Hoping I will get lucky and the chamber volume will be...

The specs in KB catalog show the compression height at 2.057, should work out to about .024 in the hole. With a 440 source stainless steel shim gasket @ .017 That calculates to 10.0 CR. Not quite the goal, but I would call that good enough. I would much prefer the thinner rings but for the car...

I agree with your thinking: try to stay with the efficiency of a flat top piston by cutting the deck and heads To arrive at the optimal 10.5 I’m looking for. If this 440 was what I would call a ‘serious’ build I would flip the money $$ and take it to that level and more. The price for the...

KB 184 is the closest that I have found to meet my needs as well. Always good to have a second opinion, thanks for posting. Steve weim55 Colorado

The engine is completely disassembled. I’ve tossed around cutting the decks, cutting the heads, thin head gaskets…… Quick, easy and cheap: .017 steel shim head gaskets, .020 cut off the heads will only get me to 9.1 CR I’m trying to avoid mission creep and do this on the cheap. Yes, the open...

Recently picked up a 1971 440 with 346 heads. .040 rebuild with very few miles that after teardown looks absolutely beautiful to bottom. Engine has only one issue I can’t deal with: Low mechanical compression. I have not cc’d the heads yet but the variety of sources that I have found show it...

Mike, firsthand experience is a help, thanks! Steve weim55 Colorado

WOW…. AND someone chose the right option boxes and good colors! When you look at the type of Mopar muscle from the same era you can purchase in today’s money, I would take this car all day long! Stunning example :) Steve weim55 Colorado

Dan, i’ve been thinking the same thing for sometime. I LOVE the wide angle right mirror on my VW. I want to look into obtaining a replacement glass that I can cut into the round shape of the right mirror on my 62 300. Then simply use two sided. emblem tape to attach it to the existing mirror. I...

Are big block oil pans the same/interchange for all 58 thru 64 full size cars? Concerned there could be a difference between short/long wheelbase models(?) I posted this over at the engine section as well, sorry for the redundancy trying to cover my bases…….. Steve weim55 Colorado
