cam change? tman 590 for 55g
« on: Monday, January 12, 2009. 11:41:41 PM. »
Lifter went on me last weekend. Munged up front cam with it. Motor is 110" axtell cyls, dished pistons, 10.4-1cr, t-man 590 cams, NRHS heads have 2" intake and 1.61 ex valves. I have a set of andrews 55g cams on the shelf. What might be the performance difference if I changed to the 55's?

FYI. Lifters were Jims hydro-solids from a previous build with 15,000mi on them. 5,000 on this build :angry: I was even warned :cry:

I'd be willing to bet that the performance would be very similar, you may not even be able to tell a difference.

Tried contacting the manufacturer?  Some folks here have had lifters fail, made by another manufacturer, they replaced their cams and other damaged components for free.  Couldn't hurt to check it out, shouldn't have to eat that.  The lifter should last longer than that...

Don't get me started on Jims POS lifters.  :angry:

I know, I've been raggin about this subject for 3 years.
4 or 5 more years of venting and I'll be over it.  :smiled:

Anyone have a suggestion on what lifters to use. I just had a SE lifter fail.

I believe you would lose  some of that low end grunt ,but would work pretty good in the mid and top.

The specs are almost the same except for Lift and IVC...you loose some low end torque; otherwise you will not notice much difference.

As far as lifters, just go with HD-Bs, especially at those lifts.  I had several "high performance lifters" fail and will never use anything else except the HD-Bs.  My lift is .660"

Try Crane Chevy small block roller lifters, available from Crane, Summit Racing, etc.  Part number is 10530.  Have been using them for last three years and are as good as OEM and better than SE or Jim's.  S&S also have performed well.  Small block Chevy 16 pcs for 200 bucks. :potstir:

CompCams VThunder lifters are a real bargain. They come in two flavors, street & high performance.

I already have a new set of B lifters. I just wanted to know If I was giving anything up or gaining anything in switching cams. I figured I might give up a little low end torque but I might gain a little top end. I liked the way it ran with the 590's.

Heard good things about Headquarters Black Ops lifters. I have a set but have not installed them. I think they run $40 each. Each individual lifter has been tested for proper bleed-down rates spec'd by Mr. Coffey.
