401B5LUN: 285/295 252/261@.050, .525"/.525" 106 LSA - Solid
Just wanted to resurrect this. I started taking this motor apart. Main bearings looked good. Cylinders still have the cross-hatch in them. So far so good. I just found out that the truck that it will be going into has 2.73 gears. This ought to make for some lackluster launches with the powerglide. I am going with a 2,400 stall in the glide as that is what I already have. Looking for any more input on the cam selection for this. Since this a very budget build with left-over/spare parts I am using one of the cams that I already have. Choices are:

1. The Lunati listed above.

2. Lunati 290/297, 235/240@.050, .490"/.490" 112 LSA - Hydraulic

3. Crower mechanical flat tappet, .528/.545 lift, 256/262@.050, 294/300 adv. dur., 114 LSA. Part # 00323


What do you think given the highway gears and low stall?
 
i think i would be going with #3. should make strong bottom end, but i'm unsure if there will be problems with too much compression. i'll let the rest of the people that know more talk about that.

A lot of wheel hop......and another fan belt throwing issue.....Still have some tuning to do. I need to get my 3" pipes and aerochamber mufflers back on it. The 2 1/2" and cheap turbos don't do it justice. The small block had a deeper sound to it than it does with the big block and the current exhaust. I imagine that the mufflers are the main culprit. The aerochambers have a nice deep rumble to them. Traction on street tires is still pretty well non-existant anywhere under 40 mph. I know I can fix the wheel hop issues pretty easily. I just need to let some air out of the shocks in the back. I probably won't do this until I get the exhaust fixed or my second topcoat on my driveway. I need it up so I don't rip the exhaust off pulling into the garage. I do need to fix out my belt alignment issue. It is kind of annoying to throw the belt. I am used to keeping a good eye on the temperature guage from the same problem with the small block. Now come on Joe, give me a little advice on the small block cam question. :)
 
None of those cams will be any good unless you get some gear in there. You could go with the Lunati Hydraulic, but even with it, you will need some gear and converter. Really a compromise, and you will be disappointed with anything until you get the gear and converter.

I would get your gear, put a TH350 in there, and put that bad @ss 401B5 back in, and let the fun begin.

I am leaning towards the 401B5. It will be a while before I can really do the gear or the transmission since I have blown most of my mad money on my big-block swap in the chevelle and purchasing the swap parts for the s-10. I know it will probably be slow off the line with this combo but it may be a little bit of help in getting the truck to hook on street tires. It should run pretty well from a 40 mph roll though. It isn't really anything I am super serious about. Just looking to have something to beat on that I am not worried about tearing up.
