Now the search for a newer & better cam is required
I race a 408 stroker with KB744 pistons and Eddy heads with Hughes 1111 springs
The 590 cam worked great for years but when i changed the lifters to EDM style i had a lobe go on me
Yes i did do the proper break in again but this is the second in many years i lost a MP cam when making changes to them
Car is a 77 Aspen R/T with 904 trans 5000 stall & 4.30 gears
Usually ran 10.80-10.90

Go roller. .650 lift will be a nice pick up if you have a good converter.

Been streetin a good sized Isky solid roller .680.660 276-281 @ .050 for years and love it...........

I have a 590 cam for sale and lifters all matched to the cam less then 1k miles on it

No Thanks
I used it since 09 and it did run a best of 10.76 but i need something more up to date

I have a 5000 TCS converter in there but not sure if i would have enough V/P clearance with that lift?

Do I understand this correctly, the 590 was fine, you switched to "the best thing since sliced bread" lifter, and wiped a lobe. Is that correct?

I guess this is one of those instances where two people interpret the same situation two different ways.

I heard, "I put new lifters on my 8 year old cam and it wiped a lobe".

Which made me think......."why would one try and put new lifters on a well used cam"?

I have added a couple of things to my list that I got away with years ago but will NEVER try again.

1. I will never buy a used solid lift cam.
2. I will NEVER take a good used solid lift cam from one block and install it in a new build. (different block)

ME; I will NEVER buy ANY solid lifter cam for ANYTHING...........problem solved..........

I haven't totally given up on them. I've gone low 9.50's in my small block with them so they have their place.

I use a solid lifter (tool steel) in my RBRE 496 ci.
Gone 9.08 @ 146, I have thought about a roller. Maybe when I want to hit the 8s?

Don

Good #`s and obviously they work as you and others have proven just never again for me personally............

That .590 cam was good in its day, which was at least 30 years ago. There is so much better out there now. I went roller awhile back and will never look back.

Thought that too

Yes I agree so i ordered a Comp cam 20-740-9 Extreme Energy Roller
286/292 duration 248/254 @ .050
.576/.582 lift
110* LS
106* IC
Will be running HRC91717 Howards lifters
Heck of a lot more $$ then a flat tappet but better in the long run

Remember the bronze dizzy gear. Cam button, and check cam endplay.

Yep ordered one of them also

I like the specs of that cam. I think you will pick up power across the rpm range
