Advice on a build up.

i'm just beginning a bare frame build up of a '75 Scout II. actually it's not to the frame yet but close. first i have some basic questions. this scout was my dad's and now that the floor boards are now non-existent he's handing it over to me to work on. the body is shot from rust (surprise, surprise) and is going to be replaced. first question is how do i find out what engine is in it. my dad doesn't know and i don't know where to look on it as all the original paper work has vanished. i know it is either a 304 or 345. i've looked all over the engine but it is all covered in oil and corn husks (a mouse lived in it for a while) and i can't find any markings as i don't know where to look. i'm considering a chevy 350 swap as i don't know how easy it would be to get 300hp and 350 lb-ft torque out of either the 304 or 345. that is for the same cost as getting it out of a 350. second, is doing a reverse shackle worth the effort. i am planning on reversing the shackles and putting on 2" lift springs on the front and either doing a spring over on the rear with 2" lift springs or just putting 4" in springs on. Third, i want to ditch the 727 auto (do i have any buyers?!) to put in a T-19 wide ratio. do any of you guys know a good place to find one as Super Scout Specialists did have any the last time i checked. or are there any other trannies i should consider? lastly, sheetmetal or fiberglass? i'm going to have to replace everything from the firewall back. i don't know how it just didn't fall apart, there's more rust then not. thankfully the frame is alright. sorry for such a long post but i've just gotten started on this project and am excited and have a lot of questions. thanks in advance for any and all of your help.

Re: Advice on a build up.

First, to find out what size engine you have - there is a flat spot about 1" square just above the passenger side engine mount that will have the engine size and serial number stamped in it. One other way to tell is to remove a valve cover, and the engine size is cast into the head. On engine swaps, everyone has his own opinion, but if it were me I'd swap a 392 into it if the 304/345 isn't powerful enough (it'll have about 350 ft/lbs stock). On your body work, fiberglass sounds nice, but the price tag was always enough to scare me away (5K+ vs. 1200 for a good metal tub). On the transmission, keep your eyes open for someone parting out a Scout - that way you can pick up the clutch pedal and linkage and transmission cover at the same time. Can't help with the reverse shackle question - I've never bothered to do one on mine.
Hope that helps.

Later,
Curt

Re: Advice on a build up.

OK, here's my $0.02..

As Curt said, the engine ID is on the block, just below the head, on the front of the passenger side, just to the rear and above the fuel pump.

Scrape the grime away, and you'll find "V304" or "V345" (or, when I looked at and bought my Travelall, you'll find the magical "V392E")

> i'm considering a chevy 350 swap as i don't know how easy
>it would be to get 300hp and 350 lb-ft torque out of either
> the 304 or 345

Is there a reason why you need "300hp/350ft-lbs"? My stock 304 motivated my Scout II just fine - with a 4" lift, 33x12.50s, 4.10 gears.. and would accelerate up a grade while flat-towing another Scout II behind it - in Montana.

With my fresh 345, it's even better - though the wide T19 isn't such a great towing transmission. (With a set of headers, my 345 should be making about 340hp/385ft-lbs - and the motor isn't anything to write home about)

I've been working through some combinations and estimations and lookin' at building a 392 for my Travelall that'll pull 400ft-lbs from 2000 to 5000rpm. I'll have less in the 392 than the 345.

What do you plan to do with this Scout? That might better help answer both the engine question and the suspension question.

Street machine / daily driver? Drag machine? Tuff-Truck competitions? Mud-running? Rock-crawling? Graded Forest Service Roads? Show-only?

Given what you've stated thus far, I'd probably lean towards a reverse-shackle and 4" springs in the front and a SOA in the rear.

On the rust - where do you live? Will it be rusting through again? FG becomes very attractive when you think of doing all of this work again in a few years.

I need to start fixing my tub - specifically the front body mounts, the rockers are starting to get a little weak, and definitely the area behind the rear wheel tubs - oh yeah, and the quarter/end-cap I smashed in on a tree.

My plan is to repair the steel structural stuff, then slap fiberglass on the outside. I have some FG quarter panels that'll be going on. At least the FG won't show any dimples - either straight, or broken.

Thus, I'm looking for suggestions on Dzus fastening the FG outer panels to the truck. <G>
