What HP/TQ do older Cammed 368's Post?

[alnukem]

Thanks, Tim

[Kevin]

Probably mid 400 at the wheels

Any Idea on Torque? Supposively, this car was 459 RWHP?

Get it to a dyno. The more recent 5.7L modified ZRs run very similar to the older 368s. I would guess ~400 rwtq, maybe a bit more because of the additional displacement.

Sweet......when I got it, it was wounded. I nursed it 500 miles to Chi-town. It seemed to have some kahunas, but I didn't want to test it too much.

Sorry guys, I'm just anticipating!

I thought you had a 385?

[LGAFF]

Yep, unless you changed the liners, etc...it was a 385ci

[alnukem]

I do. But I bought "Mitsumark's" car also last year....the guy you lent a chip to. It seemed like a good deal.

You will probably need to put in new intake cams

Why do you say that?

[LGAFF]

if they are JEal cams they tend to fail; unless the car has good oil flow to the cams

the early jeal cams were fine. it was the later ones that were bad. If it hasn't broken by now it's probably ok

[LGAFF]

Billet cams were the issue; its hit and miss. I have a Jeal cam car on my lift right now

I'm going with this. It ran strong.

Al, My 415 car had Jeal cams in it. The cams are in the 441 now. They have @ 50K miles on them with no problem. Use oil with a high zinc compound in it and forget about it. As stated above the early cams are fine.

This is the note Geoff sent to me when I asked...I was trying to save the cams in my car. My cams seemed fine, but they are the Billet Steel. This is why I was asking in another thread about possible oil passage issues in early production heads; causing lifter tick..maybe even the lobe failure I posted. I was curious if the cam failures seen by some were 1)always early production heads 2)the same cylinder.

Corey Henderson also has Jeal EA22 cams and no issues...

For the record Geoff is a super nice guy also pretty accomplished....Jaguar XJ220 program, ZR-1, and now the Dodge Hellcat.

So if you have the cast version and or billet no oil pressure issues you are good...

Hi, we used nitrided EN40B steel for the first run and chill cast iron for everything else. The issue is not heat treatment but engine oil pressure. If your engine had factory oil pressure the steel cams last just fine. Anything else they don't which is why we went to CCI
Hope that helps

It would be nice to see Geoff come back into the ZR-1 community

Frank what oil did you run, what is the idle set at?

Lee,
Can you please explain factory oil pressure further?

[FU]

AMO 10-40 idle should be set at 950 on the 441.

The 415 used AMO 20-50 , it was a very poorly built 415.

Lee,

I am not sure exactly what Geoff was referring to....and I did not want to press. I am wondering if maybe lower idle with lower pressure might have starved the cams of enough oil? But not 100% sure...I have never seen an LT-5 with "low" oil pressure as you would see on a LT-1 or standard small block .

As he states its not an issue with chilled cast

jeal had a bad batch of cams, late cams, which killed things. His early cams were awesome
