Ok,this is my first post so cut me a little slack please. I am getting ready to install a streetrv head and 268 cam on my truck. I daily drive the truck and travel some steep hills every 3 weeks going to the place I hunt here in NC. I pull a 5x8 trailer with my ATV and other things on it, I assume total weight is less than 2,000 pounds. What has worked for you guys to increase torque that would be good to do at the same time as the head install? Thanks.

 

Reasonable tire size/gearing.

31s on heavy steel wheels are a killer on these trucks.

 

I am running a 30x9.50-15 on aluminum. I am about due for tires and may drop back to a 235 then. Has anybody tried a heavier flywheel?

I wonder for my application if a lighter or heavier flywheel would be better? Or, maybe one in the middle? I'm not sure what the factory flywheel weighs.

 

LCE header may help. Also vote for re gearing

 

I have read mixed reviews on the LCE header. Most of what I read is that particular header just moves the powerband back up higher in the RPM's. Is that true? I am kicking around the idea of going ahead and doing the bottom end while I am in there. It still has very good compression (1=170psi, 2 & 3=175 and 4=180psi). I know that if I don't do it now and have trouble 6 months from now, I'll be kicking myself. I have also been told that boring the little motor does little to nothing for it. I'd love to do a stroker kit but that may be a little pricey for my blood. I appreciate all you guys' help and if you have anymore, I'd be glad to hear it. If I'm asking stupid questions then please forgive me. Thanks for the help thus far.

 

im having a motor built by putney's custom machine/ 22reperformance.com. They said even though LCE is competition, it's the only header theyd recommend.your compression is fine. regear it and if you want get the lce header. it'll be great with the cam.

 

I did an lce torquer cam and matched it with their header and have a VERY noticeable increase in power.
I 2nd the header!

 

MY 268* cam/Street RV head and LCE header definitely add more pep when all combined. Also have cold air intake. Supra AFM was throwing codes and running rich so I swapped back in the OEM AFM...stilll pretty damn peppy.

 

essentially, yes - a 4-1 style header will kinda move the power to high RPMs - great for hwy or high-speed stuff. if you want low-end power you need to keep the header in a 4-2-1 (tri-y) configuration like it is stock to get the back pressure, yet still be high-flow. there are only 2-3 companies making this type of header, like Doug Thorley, Stan's Headers, NWOR, etc. i just upgraded my exhaust from stock header and 2" pipe spliced about 1/2 way up the downpipe to a 2" Magnaflow CAT, then 2.25" out - feels significantly more powerful just opening things up and making it free-flowing since both CAT and muffler are straight-through design.

cam will definitely reconfigure where you get the power - it will be lower RPMs than before. regearing will also be a big improvement - 4.56 gears are fairly abundant as the next step up from 4.10 stock - used diffs and would be a quick swap and you might be very happy with them and your current tires (ideal for a 31, so the current smaller diameter will = more power)
