2 x 4? Meet jaw of a stubborn mule. CHANGE THE CAM!
well put crd
Mr 318250 you are all over the map, do you think there is some kind of magic to changing a cam? it is way simple/cheap and compared to chassis rebuilds, and tranny swaps???? come on.

I orderd the spring kit and the advance limiter. is there anything elts ill need for the dissy?
I was all in favor of help'n, now not so much,,,see post # 10, your base may not need to be as high as 26 IMHO but your total should be 34- 36 without vac advance.


I am outta this one, good luck to ya

By the time you pay the $400 for the truck, and get new ubolts, and all the other stuff that will be required to swap axles from a 3/4 ton to your 1/2 ton, you will be $600+. A cam swap is the best, most cost effective and least expensive of repairs for your issue. The cam is $123.xx on the comp website, lifters are cheap, $30 in gaskets. You will be under $250, and you will have a truck you can drive, that will actually pull the stink off sh1t. With pretty much anything you do with the 292 cam, with the parts you have, it will be a turd. The heads will run out of breath just as the cam is waking up. The stall speed is too tight, killing any hope of launching this tank. The gears are too low, numerically. To make this run, you will need $1500-$2500 in parts. Simply changing a converter and gears doesn't change the fact the whole combination is mismatched. We have all overcammed and engine before. It is a simple rookie mistake. Yo have been given some good advice by people who have "been there, done that". Some have given advice on how to crutch the issue, and others have advised on how to fix it. To fix it you need to match up your combo, be it to the cam you have, or a cam to the rest of the truck. Price it up, you will find a cam swap to be the most affordable, and net you the most effective results.

Stop being stubborn.

Hey fbird! I dont know what cam that is,I was gonna tell him to get something in the order of.
.450/.460 220 @ .050 112 LSA or something close to that n just use 1.5:1
I believe this is close to a cam chevy used with s/b in 60s
Also timing straight up wouldnt hurt,another confusing subject!
But I dont wanna confuse him any more that what he already is!

Stall

If you dont run a stall speed of at least around 2000 with your setup you will have problems with the engine quiting when put in gear. ( requiring you to idle the engine high to compensate for the rpm drop when its put into gear.) The other reason for the stall is with a larger duration cam you will be making more top end power, thus for a good hard launch your engine needs to be closer to its power band. The stall allows you to reach a higher rpm when the brakes are applied instead of just sitting there and getting louder lol. I have run this exact cam in a customers truck and got by with a stall around 2100. I also ran around 24 degrees of timing (advanced) and this is to be set with no vac. advance hooked up. Goodluck!

Why is there never enough time or money to do right, but plenty of time and money to do it over? And over? And over?
