ElMariachi knows first hand why the change. I have 3.46 LSD in my backdraft. In order for me to comfortably go up in class at BBORR next year I'll have to run 140 for an extended amount of time. My car has no problem doing that now, just at 5200 rpms not sure how long she'll stay together. Keith Craft builds a hell of a motor and it currently cruises well on the open road at 120.
I also drive a considerable amount on the highway and it would be nice to run 70 not at 3200. I'd be foolish not to admit it may even help my gas mileage a tad. I got 6.5 in the BBORR averaging 110mph.
MLN> read your post, doesn't look like too big of a job, always good to have a little help before you get started. ps> I found the other radiator
twice the cost of the Backdraft radiator.
Brent> Thanks, I'll do that. I have punished the drive train just a tad over the last 19,000 miles, may make sense just to change it since I'm that far in.
