Supercar Reunion #8

[DirtyS]

It's an 80's resto that could stand to be redone, but it's presentable. Drivetrain is getting done currently, but I plan to repaint the stripes in black and the wheels argent to make it correct appearancewise.

Thanks for the support guys. Hope to be able to make the SCR. Perhaps Rusty would like to do battle with another Olds?

Guess I better throw something in the donation jar.

[Mr70]

Nice Car!
I would enjoy seeing more of it at any scheduled shows you plan on attending this year.

I'm going to TRY to get my '68 Olds looking presentable and running strong before SCR... I'd love to bring it along and play with the big dogs. Right now money and time is limited for me, so we'll see.

I've got a question for anyone who has had a fair amount of experience Olds big blocks. I've got my choice to either put together a '70 455 OR a '65 425 or the original '68 350. Which would be the better choice? I've been leaning toward the 425 ... but now I'm unsure. Anyone been there done that? I have all 3 engines all requiring about the same amount of work to put them together.

What I want to end up with is a '68 Olds that looks like it rolled out of Motion Performance at one time or another It'll be Day 2 to the hilt for sure. I will settle for nothing less!

JoeG.. you have any more pics of the Motion Oldsmobiles anywhere???? Or anyone else have any?

[Belair62]

I hear the 425 is not the best choice...go with the 455....Olds guys can chime in but the 425 has a wierd bore and stroke or something...

[JoeG]

Pretty sure the stroke in the 425 is similar to the 400 --but obviously the bore is larger---Would be nice to do W-31 clone you could cam it to get good response with the turbo---You would have to do a little more tinkering with the 350 than the 455----Probably would get more Grunt for less money with the 455--

What photos are you looking for--

[55chevy]

Joe. Any photos of Oldsmobiles done by Motion. I've seen very few.. maybe 3 or 4. I know there's probably not alot out there but if you know of any more I'd love to see em.

Bob. The early 425 like I have has a different degree lifter bank angle and size than the 400-455s of 67-up. I believe the bore is the same as a 455, just shorter stroke. I know a good bit about Oldsmobiles, I was just wanting to hear some input from guys with real world experience that's already been past the stages I'm at right now with these engines. I've owned big block Oldsmobiles since 1997.... but I have YET to actually have one in a car running.. haha. I don't know whats its even like to drive a big block Olds.. just haven't had, or made, the opportunity to do so yet. I've always run Chevys. But I've always loved Olds. go figure..

[Belair62]

Before W 30's went nuts I was looking at 69 vs 70....all the Olds people I talked to said go with the 455...they talked about internals..

[Chevy454]

Holler at dehw31...he worked at Oldsmobile for umpteen years, and still has the '68 W31 he bought and walked down the assemblly line. He lives and breathes all things Olds...

[JoeG]

There ya go ED--if you talk to dehw31-ask him if he was familiar with the Motion/Markowitz Cars--Maybe he has new info or photos--------------

[SmallHurst]

I know some, but I have never claimed to be an expert. You are correct that some 425's had a different lifter bank angle, not really a problem if you know it up front as there are cams made for that angle. The 425's had steel cranks and were notorious for being quick reving BB's (sound familiar to all of your owning 427's!) The big bonus for the 455 is the extra cubes and that most everything in the aftermarket (There are some things out there ) is geared to the big block (but everything that fits on the 455 will fit the 425 as well). However, it was correctly stated that you need to talk with Dave and Casey. Anyone who can make a Pure Stock small block run in the 12's has some good ideas. I am planning on being at SCR8, so if you need to have a ride in a slow boat, let me know!
