aight so for a while there I was spending time on the truck and the wife wasnt happy...

so I laid off of the truck and spent time on other stuff....

however..
took the truck out yesterday and had a few problems.... so I am so mad that I gotta work on it again...

1. pulled up to a light and applied brakes... they maid a groan...
a. gotta figure out front or back (believe back)
b. need to put that adjustable prop valve in
c. think I fried the rotor when I put the pad in backwards when I did the disc conversion :wall

2. Alternator is bad and discharging the battery leaving myself and son stuck at a store until I got a jump from my neighbor
a. tried the 140 amp alt upgrade
b. couldnt get 140 amp alt working so put original back in
c. Need to go pay $30 for a stock alt

3. My biggest problem. I got rapped on the motor I bought... I bought a 1991 Chevy Caprice 350 Police motor (9C1 package). I was told 4 bolt and 260+ hp.. YEAH RIGHT
a. lost 2 pistons and replaced them
b. truck drives but cannot get out of its own way
c. NEED A CAM


ok so I can fix 1 & 2 but need recommendations on a cam (3)
I do not want to go radical as I want to retain some gas mileage... anyone with cam recommendations?
motor stuff....

1991 350 2bolt not 4!!!! - guy screwed me there
190hp - 350ftlb torque - guy screwed me again
hydraulic roller cam / lifters
1987 camaro dual plane intake
holley truck avenger carb


I want something with power but dont wanna have a gas hog.. believe it or not the truck is good on gas right now.... however a few months ago I raced my bro in his stock 1995 jeep 4 banger stick...he couldnt keep up... that is the only thing I have been able to do that to... I know I dont have a race car but nowadays you can get trucks MOVING.... I have no problem taching out the motor to 5g in seconds.... just seems like there are no gonads to this truck...
also when my neighbor came to jump me yesterday... we lined up at a light on the way home.... he has a ford ranger 4 banger fuel injected... he pulled on me and I stayed with him but he was 1 truck length ahead and I couldnt gain on him... I WAS PISSED!!!! AND GOTTA FIX THAT!!!!!

other option is 454 big block... although I can get one for like $300 but in the stock form... it may not perform as good as if I put the $300 into a cam and I could get the 350 to tach higher as bb's dont like rpm's (i believe)

sorry for the blabberin just annoyed....
 
also I have a hydraulic roller cam setup in my truck...

what is Hydraulic Flat Tappet Camshaft?
is that the same?
I am looking at the following:
Xtreme Energy XR258HR Hydraulic Roller
Comp Cams 'Xtreme 4x4' Hydraulic Flat Tappet Camshafts
 
For your cam questions contact Comp Cams they will get you wat you need. There is a difference between roller and flat tappet cams. They are not interchangable. Stay with the roller, less friction in the valvetrain.

There is no replacement for displacement. You could bild the 454 to peg out at 6,000 to 7,000 rpm if you wanted but that would be expensive. I think what you are looking for is torque. That's that nice feeling of having your head bounced off the seat back when you hit the throttle at a dead stop. Upper rpm hp is not something I would consider a key issue when selecting a motor or performance parts to get a 5500 lb 4x4 moving.

One thing

One other thing, if the replacement pistons you used weren't the same as the factory pistons you may have a slight compression problem. If the pistons were 2 out of a junkyard then no problem as long as the were the FACTORY installed pistons. If you used 2 from the parts store then you might have a problem due to differnt pin heights in the piston. What usually happens with some aftermarket pistons (KB-Silvolite and Badger are famous for this as well as others) is the pin is moved down to allow for the block to be decked and too slighly lower compression to guard against detonation. If you have pinging or detonation chances are its those 2 cylinders. Good luck............

stock?
I can get a stocker around here for $25....NEW
I have the 140 amp alt.. tried the upgrade but wouldnt take... autozone tested it and said it was good.. however I am not sure that is the case...
Thanks

a friend told me that one of my biggest problems may be the fact that I have a STOCK 1987 z-28 intake on my 91 motor.. he said that any intake over stock you will see a difference... plus I dont remember if this intake actually fit right.. think we beveled out the inner holes to be able to bolt it on..this was a temp fix.. to which we know how that goes.. once on.. that temp becomes permanent...


oh yeah... also my bud has one of those electronic dudads that you suction cup to the windshield... and it levels itself.. then you drive like a maniac.. it tells you your 1/8th mile time, 1/4 mile time, max torque, max hp, etc.... gonna do that tomorrow if he shows up as he said he will be over at 9am :grin:
 
anyone wanna gamble at the weight of my truck??? :rotfl
gonna need that for the gtech that we are going to use on it tomorrow.....

stock truck +
40's on steel wheels
rollbar, double tube bumpers (weigh more than stock)
not much else is different...

well I didnt need the truck's weight...

anyhow.. I am very ticked right now.. dirtbike is going up for sale so I can get some money up...

my 1/4 mile time the first run was 19.60 @ 64mph (thought the clutch was slipping)

second run was 20.80 @ 60mph (Clutch was definitely slipping as you could smell it...)

so now the clutch is going so that doesnt do me any good...however the HP numbers were SUCKY.. and I MEAN SUCKY!!!!!
125hp to rear wheels and when the clutch was really slipping (second run) 115hp

my friend has a new dodge hemmi and I think they are rated at 340hp? his runs this unit shows him at 260hp... 80hp lost through the drivetrain?????

anyhow.. dirtbike needs to go then I will get a cam, intake and clutch....
the unit we used (cant remember the name of it)... they ran it down the track and it is acurate... uses G force to get stuff.. was cool... even tells you your angles your driving on and all.... now once I do all the stuff above.. I will use the same unit to test again.. then get the HP difference.. will help to get a bearing.. then I will go to a actual dyno....

so what clutch do you recommend?
gonna get the comp camps xtreme 4x4 cam
what intake???
