welcome to the board Jason. I have located my old 377 short blockout of my old white truck! We might be able to get it cheap!

Nice looking truck!

Re: What do you think this ran
 
The 3.08s are probably helping you launch better since you have the peg leg. I would guess that the 3.73 would make traction hard to come by. Although if you get a good launch then you could cut a couple tenths off I imagine.

I will be picking up a complete rear
end out of a 68 truck with a posi
unit and 3.73 gear. I am just going to swap axles if possible. Some say it is others
say no go. But we will soon see. I will post new times when I get it all swapped. Thanks for all comments it is a work in progress.

Good looking truck Jason. But it was faster than that when it had the 305!

Re: What do you think this ran
 
come on now Sam I'd rather have a sister in a whore house that a brother with a 305!


Welcome to the board!

Jason said the 305 has made him a great boat anchor. Heck I did'nt even know he had a boat!!! Thanks for the welcome Kevin. Jason just messing with you. You really have that truck getting up pretty good. I went by the old house today to see if the rear end was still there, it was! Give me a shout when you are ready. Later Sam

Re: What do you think this ran
 
I will talk to ya about picking up the
rearend tommorow. The 305 is actually in a 55 chevy bel-air right now being used as a mock up motor.
Thats the only thing it is good for now after it came apart on me at about 5500 rpm.

sams442 02-11-2009 10:10 PM

Re: What do you think this ran
 
It would be nice to know what it would have run at the track with the "mock-up motor" Ha Ha. Just to compare !!

yeah that just ain't right. 3000rpm at 70 with a 31" tire would have to have 3.95:1 gears. A 3.08 gear will be at 2300,, or you got one TRASHED convertor!!!

americanmusc1e 02-14-2009 08:07 PM

Re: What do you think this ran
 
yeah, but my speedo's off a little too. I got a warning driving 55 in a 55 zone, the cop didn't tell me how fast i was going but i slowed it down by 5 and havent had any more problems and i'm not entirely sure about the gears but i'll pull the cover off and check

Re: What do you think this ran
 
Note to anyone that is going to try and swap your 71-72 5 lug axles in a 67 to 70 six lug rear its a no go. I had some people saying you could, and if they did something can not be right. The 67 to 70 housing measures 57" while the 71 to 72 measures 58". Any way i ordered a mini spool and 3.73 gear to fix that peg leg.

Re: What do you think this ran
 
Sweet, what brand of mini spool? Auburn? When you get to installing it post up some detailed pics if you could, I need help installing mine :D

jgreene0717 02-16-2009 01:15 PM

Re: What do you think this ran
 
Hopefully by next weekend I can have it installed. I purchased the auburn mini spool from Jegs. I will probably have someone with a little bit more experience install since I am changing ring and pinion. Not sure if I will be able to get any pics unless I watch.

Re: What do you think this ran
 
For anyone who cares I went back to the drag strip. The only changes that were made were the 3.73 gears, mini spool, and 28x12.50 MT ET streets. It is slow compared to some of you guys but it is just a street truck !!!

Best 1/4 ET @ mph: 14.41@92.89
Best 1/8 ET @ mph: 9.19@76.16
Best 60 ft: 2.10 on MT ET Street
Engine: 350
Transmission: TH-350
