Hot Summer, time for upgrades

On the tranny gear change.....just curious..... why you are going to the .64 version. What is your rear end ratio? BTW I am running the .64 as well.

Because at the Big Bend road race he heard my FE was only turning 3k rpms at 105 mph with my .64.

Bill, Brent (blykins) is a stand-up guy for clutch parts, I bought my McLeod stuff from him. His customer support and tech advice is second to none.

Jim,

Yeah thats about what RPMs I would have at 105 too. I have the .64 with a 3.27 rear. So I get about 2,000RPM at 80mph.....and with the cam I have it takes about 2,000RPM for the motor to settle in and be happy. Can't accelerate very fast without downshifting, but thats easy enough to do.

The good part is when loafing along highway there is not much noise from the pipes, but still a lot from the wind. I am sure gas mileage is helped, not that I am fretting over the cost of gas so much as how frequently I need to stop and fill up.

Same for me. I was really not pleased with that tall 5th gear when I first got the car on the road, but it was because I didn't have my carb and timing issues squared away. Now that its all broken in and tuned, I can chug along in 5th at 2k rpms at 75 mph and if I need to downshift to 4th and hit the afterburner, I am right in the low end of the cam's sweet spot. I love the looks when you walk off and leave other cars from 70-130.

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.
