340/E85/D1SC/FItech1200 big hp SB guys step inside please!

Ieblanc, I definitely didn't forget those. I didn't do them "the right" way because I plan to do a full resto on this car at some point in the distant future. I just wanted to slap in something that worked so I took 2x3 rectangle stock and welded it tucked up against the floor from the crossmember to the rear sub frame and welded it in all around at as many points as I could fit the torch into. Not perfect, but it is definitely solid and should do the job. I just didn't want to go crazy with tying it into the floor as I think that would have opened up a can of worms with me wanting to replace the floors while I was there. Only thing that worries me is whether or not it will be a problem that I didn't use a subframe connector that is one piece with the leaf spring pocket. I am just worried the factory leaf spring pocket may have issues with handling this kind of power but a few guys with stock pockets and stroked big block power told me not to worry.

Chargd72, that sounds like an awesome build of your own. Do you have any specs on it and what kind of power it made?
I actually found a friend who has two Derale 13" fans he would sell me for very cheap after he destroyed their shroud trying to fit them in his early 70's vette. They will bolt into the existing shroud I have in place of the cheap china fans that came with it. the fans flow 2000CFM each and draw 50 amps combined. FItech can control when the first and second fan comes on. I am just debating on whether to go this route or just use a 7 blade flex-a-lite fan. I have a 140amp 1 wire Tuff Stuff alternator so I don't think amp draw will be an issue, but I am worried about putting that much load on the alternator with a single V belt. Flex fan just seems like it would be easier and flow better at RPM's, but I get a little worried about how it'll do sitting in traffic. I mean when it comes down to it, when idling this is just a 9.2:1 low compression motor on E85...it should stay pretty cool regardless of the fan type. I'm really torn on which way to go.

thanks for the tip on the couplers! I actually found a pretty good way to route them, I'll take pics but with my intercooler it worked out pretty good. My two issues now is that the bracket I have for the massive dayco tensioner is pretty close to the procharger outlet piping, so I'm a little worried about it kissing the piping when the motor torques but hopefully with poly locks that won't be an issue. I also need to figure out where i'm going to have room to weld on the Mondo bypass valve. I'll take some pics of the piping when I get back to the shop to work on it.
