Thats not true, a dude from my area made 998rwhp on a stock block and has been on his same motor for a couple years. The cobra motors come built very good from the factory they come with arp rod bolts and other goodies. Dont hate on it just because it a ford i have respect for these cars you need to give respect when its due. I cant believe you would make a comment like that obviously you nothing about these cars.
Here is a vid of marks car all stock motor with a 88 on it. And he was the highest hp stock block until i saw this thread.

My buddy has worked on his car before he hasnt gone threw that many long blocks. Your right im not good enough friends with him to know alot but my buddy has worked on his car since it was a twin screw setup. He went threw 2 due to the car running lean which he claimed was his fault. So what does that prove? Anything will blow up if its lean. Doesnt prove the fact that they can with hold it or not at the stage of tuning it is critical. And he never blew it up on his 76 kit.

He did but it wasnt the power level, it was the alch injection..but what ever, he has really started having problems as of late trying to get over the 1000 Hp hump.
Reguardless of the set-up the pistons or head gaskets seem to exit when he starts pushing the 1k level.
I know for sure there was at a minimum of 4 long blocks this last summer. He has the package working well tho as its went 8.95 and in the 150's..... still leaving soft.

IAT isn't as bad as yall think. the efficiency of the roots is much higher in this case than normal. instead of making 25psi, or 25x normal out of the roots blower, the blower lets say doubling or tripling the boost from the turbos, so only 3x

Ussing the root's blower takes alot of lag out of the setup.In low rpm area's we gained 2-300hp over just the twin turbo.The root's was pulleyed for a high boost but made crappy power.We then put on the stock pulley and made a great deal more.Over spinning the blower just introduced a ton of heat. The twin turbo's are intercooled before it hit's the stock setup,also there is a meth kit too that helps.

I think the reason the roots doesn't become a restriction is that the air has been already compressed and cooled from the turbo/intercooler and at that point the blower is just working on the pressure differential then of input and output. Volume of air is the same, just the density is different.
