Solid lifter question

[clarkj]

Hi there. I recently tore down my broke 360 with the intention of using the cam and lifters from it in the 340 I am finishing up. I had all of the lifters laid out on my cart in order so I could match them back up with the correct cam lobe when I started on the 340. Unfortunately, my younger brother decided he needed to move them and just tossed them all in a pile, so now I have no clue which lifter goes where. How huge a deal is this? Should I buy new lifters and re-break in the cam in the 340?

Yes buy new mopar solid lifters 'they're lighter' & burnish them in.

[clarkj]

Why the quotes around they're lighter? Do you mean that they are said to be lighter but are actually not? I guess I can't really see what a big deal that would make anyway. I hate to sound stupid, but what do you mean by burnishing them in, never heard that terminology I am afraid. Thanks for the help.

Solid lifters on a hydraulic cam is a no-no, not to mention the need for adjustable valvetrain.

A-hem...me 2.

Just old terminology describing the lifters establishing wear pattern/break in ect.
Hey I'm just curious has no one ever heard of [solid lifter/hyd cam]?
Doing this the other way [hyd lifter/solid cam] would eat the lobes with the faster ramp speed and all, Not to say I recomend this.
Just a ?

[clarkj]

This is a solid/solid set up. I am not sure where anyone got the idea that it was a hyd. cam with solid lifters. I guess I should have been more specific on what cam I have. It is the MP 284/.528 solid cam. I love it BTW. I hear alot of people knock the MP cams, but sure can't complain.

[3404spdvaliant]

MP cams do get knocked alot about being 'old technology' but what made sh*t loads of power in the same engine then is going to make sh*t loads of power in the same engine now. After using this cam and experimenting with a few 340s No one will ever talk me into a designer $200+ extra 5hp under the curve cam over what I have now, which is the same cam you have =solid 284 .528. I run mine in a 340, and it RUNS just ask valiant64.
You are one of few who uses the .528 & besides my self I know of no one else, most think it's too big. not us Right on!

[clarkj]

I will admit,m when I was looking to buy my truck and the guy told me it had that 284/528 in it I was scared that it was too big and it would be a dog on the bottom end. I couldn't have been more wrong. Of course the 4.56 gears helped, but the 35" tires more than made up for them. The stall in my converter was nothing too crazy either, at 2400. I could smoke the 35s without brake standing against the converter, so I sure can't complain. This truck was a mud racer and the guy even truck pulled with it and that cam did both great and was plenty tame on the street, too. I am not saying it is the best thing out there, but I don't intend on trying a different one in order to find out any time soon!

[valiant64]

I didn't read anywhere in your post about havn a hyd. cam w/ solid lifters either. Anyhow, I woulda thought the .528 would have a real choppy idle & no low-end torque whatsoever...Wrong. It idles in 340's car like a cam a little hotter than stock, and not lacking low-end torque at all. I wouldn't use it unless I had some gears/converter/m.t., but looks like you have that covered.

[clarkj]

I appreciate all the info and feedback. I think I will buy a new set of lifters to be safe...adn smack my brother in the head while I'm at it

I used to run a solid .580 lift 312 dur cam in my 340 with a 3500 stall and 430 gears and I LOVED IT.

Also I have mixed lifters in the past, (more than once) it isn't a good practice but I never killed a cam doing it. If fact the 580 cam was used when I got it and the lifters were in a can of oil. I installed it and ran it for 4 years. Up to 7200 RPM and running 12:10 in a 72 dart that I drove on the street. Put around 15000 miles on it before I sold the car.

Burnishing is Fly Speced Lobes cousin.

[3404spdvaliant]

uhh...wow we got a live one here

[N.R.F.D.]

i have also mixed lifters and had no problem but ive done it more then once and ive flattened more cams then u want to bye so good advice just get new lifters. one piece of worning ive flattened the cam anyway after changing lifters but only once of about ten. dont forget that the origanal cam and lifters were broke in on a different block then your planning on using so even if you still had your lifters in there origanal places the lifter bores can be slightly different to the cam and this would change the ware pattern and could cause a failure anyway although rare. not trying to scare just letting you know so you dont think you got bad advice

[Paul Precht]

If all the lifters have a smooth pattern showing they were rotating properly you'll have no problem using them. I have swapped lifters from cam to cam for over thirty years without an issue. It's nice to have them in place but in a different block they're going to meet the cam in a slightly different position anyway. The lifter bores are never perfect, Paul.

hows life in Pa Paul? The 63 running Good

[Paul Precht]

It's been great. I've shoveled less snow in 3 years than I did in NH in 3 hours, not kidding. The new house is almost 4 times the size of the old one with no mortgage. The 63 is ready for some fun this year. I'm trying to set up a new tow rig because I sold the sold the Dodge van. It's my Ford E250 van or my Mitsubishi box truck. The Ford handles like a loaded cesspool truck with 3 wheels, Paul.

[Dick]

Where abouts in NH are you from, Paul?

[hotrod7043]

whereabouts in Pa paul i might have a lady friend that be moving there. she is looking for a house with land there.

[Paul Precht]

I moved up to Rochester,NH from Long Island in 88 at the tender young age of 33. It was cheap Real estate, low taxes and low crime with a heavy price to pay. 11 months of winter and the most unfriendly people I have ever met in my life. With the exception of some of my LI friends that moved there and my band and it's following, I felt like I was in jail for 17 years. I started New Hampshire Comp in 93 thanks to the promotion from Jerry Stein and High Performance Mopar Mag. The New England Dragway gang and the Sanford guys kept me busy with work. The winters almost killed me but if you can live with the cold and having just a few friends it's still a cheap and safe place to live. I wouldn't recommend it to anyone. Sorry for the rant, there are many great people in that area but it's just too cold and unsocial for me, Paul.

Hi,
Cheap insurance, buy some new ones.
Rick

[clarkj]

I doubt that I would have any trouble with my old lifters, but I am for sure buying new ones. This motor is going to last the life of the car if I have my say in the matter.
