Where do I measure from? I know it right over the wrist pin center of the piston. The 440 source dished pistons sit below the hole in the dish, .012" above the hole at the pad. Should I use the above the hole in the pad area for my height measurement? If so Summits compression calculator puts...

My 505 is toast. 2 broke pistons and the rest scored. How did it happen? I dont know yet. It denotated horribly. so what can cause that? Too much timing? Running lean? Failing fuel pump, clogged carb? Bad gas? This engine has a 440 Source 440-512-5060 kit in it. PP240 heads. That should put it...

I nicked a cam bearing while cleaning the block. So I got a set of Clevite bearings, took out the #2 bearing, Looked it over and knocked it in. Just changed the #2 bearing. Now the cam wont go all the way in. It stops about 1/8" going in to the bearing. very stiff trying to rotate it. Wont turn...

I have a worn out 72 400. I need it to replace my 505 while it is out of the car getting refreshed. The 400 is stripped down to the bare block ready to go to the machine shop. I would like to just do a rings and bearings refresh if possible. The cylinder bores have some ridge, the cross hatch is...

I should try to make a video on how noisy the engine is. It has Howards roller lifters and Harland Sharp roller rockers. The HS rockers are for Edelbrock and Trick Flow heads. I have the Trick Flow PP240 heads. This is on a stroked 440. The engine clacks like a diesel at idle, but goes away with...

I have used everything from the $29 parts store pumps to to $250 rebuildable pumps. Cant get more then 2 years of life out of them. I put 3 to 5 thousand miles a year on my 73. Thats more miles then most old cars get. But, fuel pumps are not supposed to fail that quickly. The rubber diaphrams...

I have the Hemi dissasembled. Trying to diagnose the failure. I bought it in running in a car this way. I have no history of what happened to it. It was running with three down holes, and it had an F1 procharger on it. Getting it apart we found three broke piston top rings and lands. Sent the...

Time to get the teeny cam and valve springs out and put in something that belongs there. When I put this 440 together it was just supposed to be temporary since the engine in the car was hurt. Well, now it is going to stay. What it is; 69 Road Runner convertible 1976 440 truck engine, iron...

Low compression 1976 440. Has been rebuilt using stock pistons, new rings and bearings. 452 heads with unknown springs. It has a smallish Comp XE256H cam, 212/218 @50, .447/.455, 110LSA. I had this cam and lifters so they went in the engine. The car this engine went in has an F1 Procharger in...

Ran in to a problem. Called JVX Racing for a big block to small block adpter plate. Find out he is having health issues and wont be shipping for a while. I need to get the engine and trans bolted together and in the car to modify the tunnel. So I made some 1/2" plates to temporarily hang the...

I am doing another 518 retro fit soon. Instead of using the pressure switch scheme to control the OD and LU, I found this company that makes a stand alone controler. It works best with the 46RE versions controlling everything, shift points as well as OD and LU. They offer a version that makes...

I have 18 sealed cans, yes cans, of Valvoline Dexron II. Is it still usable?

The trans was rebuilt last year by a reputable shop here in Phoenix. He does a lot heavy duty diesel trans work. He told me he put a lot of the heavy duty diesel parts in my 46RH along with a shift kit. The problem from the get go is getting the trans to shift at WOT, both second and third...

What needs to change to make a big engine spin to much higher rpms, like 6500 or so. Not looking for a build recipe, although that would be nice. What needs to change in theory? Big blocks are known for low end torque. What does it take to make it spin much higher?

The 505 makes good power, never been dynoed but pulls like a freight train. I only have oil out the breather after some spirited full throttle fun. Crank case pressure can get pretty high, the tell is my valley pan has been pushed up to the bottom of the intake and finally cracked, making an...

I had the procharger on the 383 for a while. Got it all dialed in. AFR's at WOT in the high 11's. It was running great, till it died. Cylinders 4 and 6 are destroyed. The others show just a little detonation, could pull a bit more timing but nothing destructive like 2 and 4. It is a 452 headed...

I put a new clutch in the 73. It has a stock built 440. The bearing retainer was leaking badly, while down to fix that I put a new clutch in as well. The old disc was oiled up so even tho only 2000 miles on it, it had to go. I got a Zoom MU 1858-1a from Summit. Stock replacement Borg and Beck...

Starting the rebuild of of a Gen II Hemi. Are there any books that cover this in detail? Any tips and advice is welcome.

Mcleod dual friction clutch. Very disappointing. It is supposed to handle 500 HP. My 383 was only 300 at best. The car was on the dragstrip a few times, and spent a weekend on the autocross track. The 383 engine is out right now, my 505 stroker is going in. So I have to decide on what to do with...
