What's more important?

[Sledheadxp800r]

Im wondering if it Would it be a good idea to run a girdle or all season billet rear engine plate or are these parts overkill? Would you run one over the other? Im unsure of what its going to make for power when it's all together. What do you guys think It will be capable of powerwise also?

I was told by an "expert" that the way the duramax main caps are bolted in, that a girdle is not needed.

i have one on my built LB7. Theres a lot of guys out there just running the girdle with standard caps. looks like you havent spared any expense yet, why stop now?!:thumb:

Why stop now? I'm running out of money. :roflmao:

I feel your pain, trust me.

Some say they are needed & some say there not... So flip a coin I guess.

Power should be in the 800-850 range, just a guess.

 

[delong_1]

IMO do the girdle

 

[Harbin_22]

What is the big advantage to the rear cover? Do yet actually break or is it just possible coolant leak

 

[Sledheadxp800r]

I guess it keeps the block from breaking.

 

[delong_1]

from what i understood is the stock rear cover has some flex and can leak coolant under power but at least for me has never been a problem and seems like less of a problem than cap walk to me.

 

[Sledheadxp800r]

Power should be in the 800-850 range, just a guess.

If its in the 800hp range I think I'll probably run it without a girdle and billet rear plate.

i say no girdle, just main studs. and I think the rear cover is a good idea, just really really pricey...so i didn't do it. I dont mind little leaks on a competition truck

 

[quadracer37]

neither are necessary IMO. dont get to extreme with timing and you wont need to worry about your mains walking-no need for girdle.
ive heard of the rear cover coolant leaking problems but never seen it... in 1000 hp street trucks or 1300hp pull trucks on engine dyno or in the truck.

personally id spend the money on upgraded pumps or lbz pumps. two lb7 pumps wouldnt support my 80 over injectors last year, youll have a heck of a time with 100 overs holding rail.

 

[Sledheadxp800r]

Lb7 pumps flow that much less than Lbz pumps?

 

[juddski88]

you can mod your lb7 pumps pretty easily. but I would spring for those new exergy 10mm strokers

 

[Sledheadxp800r]

Yeah? What do the exergy pumps cost?

 

[Sledheadxp800r]

2200 each? Hahaha I do t think I'll be running those anytime soon.

 

[juddski88]

Thats the retail on a II 150% pump or dodge 220% pump. but These exergy pumps are going on a few high profile pullers this season in place of II or WD pumps

 

[quadracer37]

The Exergy pumps should be pretty awesome. They are ran on thier Bosch test bench just like their injectors, they cost a little more than some of the other pump builders out there but your gaurenteed a good tested pump thats going to put out what it's advertised to do.
You can put Lbz regulators on your lb7 pumps and that will help, or you can modify your lb7 regulators to I believe.

Back when I was buying my floor it pump, exergy had started testing there's. I'm sure it will be baddass and work great!
