Yikes. . . lots of info very fast. . .
1. OIL:
As fare as oil goes a run amsoil sae60 truck should have strait weight 40 but i figure 60 in synthetic should be about the same thing truck fire's up and has instant oil pressure even at -35*F fire's right up oil pressure shoot's right 65psi same as the summer time the cold dose not effect the flow rate at all a cording to the mechanical gauge as the needle don't delay and rapidly shoot's to 65psi year round if till took a few second to start building or the psi climbed slowly i would run thinner oil but it's almost instantly hit 65psi hot idleing it sit's at 55psi just tap the throttle shoot's right up to 65psi atfer driving a long time it will fade back to 57psi from 65psi. . .
I will never use an oil thinner the 10w-40 in anything especailly a synthetic. . . 10w-40syn flow's just as fast if not faster than 5w-20 standard oil. . . the GMC,M123, B61, amx, and all my summer only collector's and heavy duty truck's get the 60w... everything else get's 10w-40 in the winter 20w-50 in the summer I found my engine's last longer that way. . .If i had time i would list all the engine's i had die with 5-30 and 10-30 that got rebuild again! then ran 10-40,20-50. or 60w oil's and lasted 3 to 5 times longer and still going. . .heavy oil work's for me. . .
2.COMPRESSION:
I don't see how raising the compresssion ratio is going to make it a high RPM engine, diesel's have 18-22:1 C/R's and only run 1800-3250rpm. . .
Back to subject:
I want a brute force low ender pulling up to mid range. . .
start pulling at 1250-1500rpm rpm die off at 2750-3250 rpm, but currently it will pull till about 2200 than it fade's off fast all done by 2500 but i still gotta run it out too 2700-3300rpm to keep it from lugger out in the next gear.
i would like about 380TQ instead of 280TQ . . .
the truck is a doggy glutless wonder from 2200rpm on up when you hit the on ramp and are pulling into 72mph traffic at 50mph! truck should whined up to 60mph easy in the length of an on ramp with 8-19.5 34" tires 5.13 gear's granny SM420 trans lot's of low end torque should jack rabbit off the line. . . let me show ya what i got and what i'm looking for would be best i guess. . .
STOCK OUT PUT:
190hp@3600rpm.
280TQ@1600rpm.
Wanted out put:
175-225hp@3750rpm. << plenty of HP rev's could be lower. . .
380-420TQ@1750rpm. << low rev's big torque. . .
still able to cruze at 3,000rpm like it dose now. . . i would be happy with 175hp if i had 380-420FTLB torque to back it up with
truck only dose 62.5mph@3,000RPM and takes it time getting there empty i don't load it any more darn collector plates but when i did the extra weight didn't slow it down thank GOD! once rolling up to cruzing speed of 3,000rpm it didn't lug down any even in the hill's loaded to 14,000lb ocasionaly
16,000lb< has been that high a few times oop's dead empty if should getup and go faster than dose i think. . .
if it's going to be slow i want it to get up to speed fairly quick . . .
i don't want lot of horse power i want Gob's of mad TORQUE! ! !
I have been told if i want torque keep the rev's low and the compression high. . . high compression 9.2-10.5:1 low duration cam with high lift, big 2bbl carb has more torque than a 4bbl i'm told. . .
