I read an article a few years back in a performance rag about some big bore/short stroke engines that were built by what I remember as a performance engine school in the Houston, TX area. Does anyone have a copy of the article or know where it might be posted online? I know I've seen references to it here, so I'm hoping this rings a bell with someone else. I'm leaning toward a similar combo and I'm curious about what they used and hoping to learn a little from their efforts and $$$. Thanks!

Yeah, you're talking about SAM. School of Automotive
Machinist. You might try doing a google search on that and see what turns up.

Found it, thanks. Looks like the hot ticket. Theirs are 477 ci with 3.76 stroke and 4.498 bore. I'll have .100 bigger bore and the resulting 23 cubes.

I know those guys pretty well. You better think about the whole combo. Those are 8600-9000 rpm buzz bombs!

Judson,Pat and Casey build these things under the premise that "...anything under 4000 rpm ought to be pulling into a parking place!"

The last version was running high 8's@154 or so in full weight Malibu.

:D My kind of rat, brother! :cool:

Link?

Try this link, from Car Craft awhile ago. Good reading. SAM '79 Malibu (http://www.carcraft.com/featuredvehicles/65178/index.html) Daren

"set of heavily ported and milled cast-iron GM Performance Parts aluminum heads "

Where can i found these? ;)

I like the 1.45 60's on 275-60 Drag Radials.

If you cam it right and don't go overboard on port size, it should still make some good grunt due to no more then it being 500"s, imho...

But if you want a Pro-Stock motor, then it will be a dandy too...

But if I was to build one using a custom block, I would make a standard deck height 4.6"b x 4.375"s = 582" motor and call it a 396"er... He, He!!

Use a 6.4" rod and needed piston
