DSS Main Support - worth the dough or Waste of money?

Teksid block, near 700 supercharged HP... enough to need one of these?

Couldn't hurt, IMO. I think of that main support like subframe connectors for your engine.

nope, if you have the later aluminum block you have the webbed top for more durability for 700hp, that thing is for mass power

I have no reason to doubt you, Tom.

DSS Main Support & ARP main studs = $331 +shipping
ARP main studs + Windage tray = $260 +shipping (roughly)

Seeing as I still have a new flywheel, clutch, electric water pump, oil pump, k-member, LT headers, head studs, and all the gaskets to purchase before I can have the new longblock assembled & installed, I think I'll stick with the studs and tray for $260.

I was thinking it was unlikely that the 03-04 Cobra guys pushing 700 HP werent' opening up their bottom-end just to bolt one of these on...

Normally I would agree with your thinking, but since I'm facing another (roughly) $12,000.00 to complete this project, I need to be sure that I spend as wisely as possible.

Yea if you approach the limits of the block (supposedly around 1000HP) then it would be a good idea. But for now its probably more of a waste. I almost never hear of any modular blocks failing.

I don't think you have to worry much about the block cracking like the old 5.0's BUT the main support may help reduce the chances of shifting a main cap, if your going to be making 700+hp any extra support to the main caps won't hurt. Cap walk is not as much of a problem in these motors as in the older 5.0's but it can still happen at that power level.

You didn't mention it here on your list but would you have to run a different oil pan if you use the support? I don't know on modular motor but on the old 5.0's the stock oil pan usually wouldn't fit over most supports.

Ya know, Chuck... I have no idea. I want to carry over the oil pan that is in the car now to the new motor. It sounds like I won't be needing the main support, so no worries.
