How to swap a big-block into an awd Astro/Safari...

[nitropyro]

peter dont forget that in a 2wd astro a big block can fit if you run a dual plain intake and a carb and a very small air cleaner! but with your ram air it would not fit.
question though i assume the 4l80 is longer than the 60? cant seem to figure out why you had to make a tranny extention.

Peter made the extension due to the mount for the tranny/t-case is place further back on the 4L80E/NP241 combo than on the 4L60E/BW4472 combo. The 4L80E is longer than a 4L60E.

Vantastic!

thats gotta be the best use of a 502 Ive seen anywhere!

theres a local shop that here that puts them in bikes.. Ive ridden one. unless you like doing rolling burnouts at +70mph theres not much point in it. you cant even rev it while sitting still unless the kickstand is down or it will just fallover due to all the torque.

your fab work looks great. is it complete or are you still upgrading other areas? cant belive you took it to the strip LOL and the times are almost as impressive as the build!

WOW

The only slight drawback with my cruise control is that the OEM computer and/or cruise control module still thinks there's a 4.3 under the hood. So when driving down the highway at 50-65 mph, the cruise control tends to overaccelerate slightly while maintaining the proper speed setting. What would normally take 25-30% throttle to maintain 60 mph takes only 13-17% with the big block. The cruise control module simply overcompensates rather than take baby-steps LOLOL. On the other hand, the only time I ever go anywhere on a long highway trip is when I'm towing the Tramper. When towing her, I need around 20% throttle to maintain 60-65 mph and the engine & ground speeds are then rock steady.

my stock 4.3's c/c always seems to over compensate anyways, when im in cruise it jumps and makes me look like a jerk if people are trying to pass me at the same time. is there a known way to adjust these units?

[Mr_Roboto]

The servo units are vacuum actuated correct? If so try an orfice in the line perhaps? Just start it off with a fairly small restriction and proceed from there. If you cam the engine up chances are that you would see less idle vacuum then anyways which may do the trick.

Where is the writeup on the trailer?

Hopefully he's still breathing, but he hasn't been on the Forum in well over a yr.

Not sure where the trailer thread is, try checking the int/ext forum or gen discussion

Peter is still alive and kicking, but not dabbling in Astro/Safari vans at the moment. (He has since sold his 502 Safari monster.)

He did recently tell me his HVAC company is getting ready to retire another Astro/Safari and he is wondering if it is time for a new project.

[1Gary]

He still has the Tramper.

[Cobra]

the lack of him on here makes me want to go down there and check on him lol

[Smiliesafari]

Peter is fine. He's had some business and family issues to deal with.

life always gets in the way of fun stuff i did hear about some of the stuff that was going on. Just making sure some keeps in touch with him can't let him get away
