FE Technical Forum / Re: 428 crank or not?
« on: March 30, 2016, 06:51:25 PM »
I think I will stay with the 390, I coated the 410 block today with some LPS 3 today. I was looking at Keith Black site for some 410 pistons earlier today, and also check prices like $350 for a flywheel, for starters. I do have a question for you, on the KB site it states where the quench is on their flat, step, and dome pistons and for the circular dish like I have with the H304p's, it says no quench.
Where I am at now at .021 deck clearance, If I used the KB KB150 Step Dish with 20cc I would be at "0" deck clearance and at 9.28 SCR and 7.51 DCR. using a .041 head gasket. With my current piston, I am at SCR 9.94 and DCR is 8.03.

Piston                                               sealed power H304P                             KB150

ICA                                                                   63                                              63
SCR                                                                  9..94                                        9.28

So can someone explain the quench with a circular dish. I was all set now I am confused about whether I need to go with a step dish for the quench effect.

The 381np cast Pistons have 11.7 cc dish with 4 valve reliefs. Could an additional 6.3 cc be taken out out of the dish to end up with a 18cc piston? Has anyone had tat done to a 381np cast piston?

Unless you live at sea level, I wouldn't get too excited about your SCR being over 10:1.
Kevin, I am at 2000 feet elevation here in Wichita KS. I started getting excited about the 410 I got because I remember having a 64 back in 71 that had a 352 4 speed that wouldn't get out of it own way, bought a stock 428 from a friend and was going about 15 mph in 1st gear and laid 1/2 block of single trac rubber when I punched it. With the 352 , I was lucky to get a chirp out of the tires. Had a big old wide grin after that.

Thank you for that very informative write-up Ross. I will stay with the 401 and clean and grease up the 410 block and crank and save it for another project. Maybe find a short bed pickup and use it for that, or sell it.

FE Technical Forum / 428 crank or not?
« on: March 24, 2016, 12:42:36 PM »
I rec'd a lot of help from Jay, Ross and Brent on a 390 build I had and finally decided on which way to go.
It is a sonic tested .060 over 390 block, 390 crank, 69 cc heads, H304p 12cc dish pistons, .021 deck clearance, 12 cc dish and a  Comp 70s cam with a 280 exhaust with 110 LSA and 108 ICL. and using a .027 head gasket with 4.250 bore, It gave me a SCR of 9.948 and a DCR of 8.031. Quench would be .048.
I would have liked to go with a 428 crank but funds did not allow for a scat crank or a stock 428 crank till yesterday. I found a guy local that wanted the cam research cam I had for sale and a pair of MT 427 valve covers I have had forever and I swapped him for a 66 410. It is a standard block but it has too much taper to not be bored. The crank is also std and had good looking bearings so it will either need polished or maybe .010/.010
So if I put the 428 crank in my block, which is still not put together as I have been working on body, and use 381np pistons with 11.8 cc,
I would be still using the 69 cc heads, the same comp 270/280 cam with 110/108 and the deck clearance would be .020. But using the same .027 gasket with 4.250 bore my SCR would be 10.464 and DCR would be 8.468. Quench would be .047.
So it looks like if I went with the 428 crank it is still gonna take some special hi dollar piston with like 18cc dish which would bring it down to SCR 9.863 and DCR to 7.994.
Any suggestions?

FE Technical Forum / pcv location,rear of intake, or valve cover
« on: January 29, 2016, 09:16:39 PM »
I've got some old MT ribbed valve covers I am thinking about running. Does a pcv work any more efficient from the top of the valve cover with the other valve cover having a breather in it than it does leaving it in the rear of the intake when still using the try under the intake? Also will have a breather on tri-power oil fill spout. Or do most of you keep it at the rear of the intake?
The MT's already have holes in them and was going to use some baffled grommets from Moroso  and also the push in breather has a built in baffle that I would hook the pcv to.

FE Technical Forum / Re: Crower cool-face solid lifters push rod question
« on: January 29, 2016, 11:13:26 AM »
You are likely correct for a shell lifter, but I don't think that is a shell lifter Carl.

A shell lifter is generally a hollow cup and could not really be made to oil at the face.  I could be wrong, but I believe those are simply a SBF lifter

This is a poor picture, but you can see down inside the lifter


You are right Ross, after checking and talking to Crower, the seat height on the cool-face lifter is 1.640 where the seat height on the dumbell that Howards Cam has is 1.796 and the dumbell that comp has is 1.790, so not a big difference like the shell lifter would be. Comps shell lifter 837 shows a seat height of only 0.470, a big difference.
I ordered the crower cool-face lifters from Brent this morning.

After some searching I found where DSC, says a 10.400 pushrod is need for solids with shell lifters so I will have to another push rod checker that goes from like 10 inches to 11 inches to measure my for sure.

« on: January 28, 2016, 10:24:48 AM »
Has anyone used the 66915X980 crower cool-face lifters. Just wondering what the push rod length they ended up with using stock adjustable rockers. I have a pushrod checker if I decide to order the lifters but it only goes up to 9 1/2 inches. Are they longer than that?

I used the Wallace i cant get the Pat Kelley to load on my apple
Found this app for the Apple iphone  today. Engine Toolbox App. Does ACR and DCR. Don't know how accurate. I have been away from home and computer all weekend to compare with the Pat Kelley one. It does ask for your intake closing point where The Pat Kelly one will put that in for you.

Changing my mind and going with solid lifter cam. Have a brand new in box cam and lifters. Cam is from Cam Research. Lifters were broke in on their CamKing machine. All lifters are inscribed as to what hole they go in. Cam, lifters cost $190 and another $60 for break-in plus shipping. Will sell for $160 plus shipping.

FE Technical Forum / Cast Piston CC volume from The Horse's Mouth
« on: January 05, 2016, 05:21:52 PM »
Just wanted to share some info I found by calling the tech dept. today.I called today and actually got ahold of a person in Tech that was very cooperative. I called Fed Mogul and United Engines and they gave me the CC's of the following cast pistons:
The forged do not seem to be a problem, they always list the cc on Summit. The 1.660 info should come in handy for the 428 crank into the 390.

Ok Jay and Ross,
I found out today the machine shop I used did not square deck the block, he apparently just made a flat service out of what was there.I decided to check the deck clearance one more time to tell them how much to take off. The last time I checked I just used #1 hole and it measured .031, this time I measured #1, #4, #5 and #8.
#1  = .031
#4  = .022
#5  = .021
#8  = .027
 I did not know at the time either, I remember asking him what the deck was now and he said he had no way of measuring it but he thought he took off about .005. I keep learning these lessons the expensive way.

I guess if I can find a shop around here that can go off the main saddle I think they should be able to cut the big end on each side and daylight out to the small end which I think would be taking off roughly .010 which would put all these dish pistons at .021.

Ross, what would the static and dynamic ratio be with that 270s cam and the .027 gasket with 4.165 bore? I used the Pat Kelly Chart and got 9.764 for the static ratio, but where is the dynamic ratio? I must be doing something wrong with the chart cause he says the dynamic is in green but mine says static.
I used 12 cc for my dish and .031 piston to deck clearance, I used the 61 degree closing on the intake and 270 duration. However Comp list the intake closing at .0006, did I do it right. Where do I figure out the dynamic ratio?
Would you install the 270s cam dot to dot. I do have a 9 keyway crank gear.
Carl
