LOVE those old Mopars! [img]<<GRAEMLIN_URL>>/drool.gif[/img]

My favorite early Mopar;



And it would have to have one of these between the fenders:



And one of these behind it:



And one of these out back:

I really liked the 302 we built for Williams (10/10 RSZ) 69 Z...

302 12.5:1, 636 lift solid roller (spec'd by Dave Crower), zero gap rings, Eagle rods, 186's with 2.05 intakes, a little bowl work &amp; gasket matched.

If originality was not an issue for an all out I would have run aluminum heads, with a crossram, and better ignition, 6.25 rods with custom pistons, &amp; a Callies crank with splayed main caps.

Can I build 2? [img]<<GRAEMLIN_URL>>/naughty.gif[/img]

Since I normally dare to be different, I'd like to try a couple different &quot;stock appearing&quot; builds...both starting with old 502 short decks, stock 163 intake w/ worked Camaro/Chevelle exhaust manifolds, but one a big bore (4.56&quot short stroke (3.76&quot combo just shy of 500 cubes, and the other with the same bore (4.56&quot but throw some arm at it (4.375&quot for an old school 572...and then see which got down the track the best on the Polyglass!

I've always wondered if the lesser torqued/higher revving Pro Stock style engine wouldn't be easier to launch, but run into breathing issues with the stock parts due to the increased revs...and everyone says to always build the biggest engine you can afford, but I'm thinking the torque could make the combo a nightmare off the line? Guess that's why we race 'em on the track and not paper...

Since you're talking along the lines of &quot;F.A.S.T.&quot; cars, how many cubes is Lane's Mustang? Isn't he somewhere around 557&quot;?

FWIW, I've already done a 4.5&quot;X4.5&quot; short deck 572 back in `95. Made stupid power for no more than what it was. Can be done with off-the-shelf parts today if you (A) run an aftermarket block or (B) a short deck Bowtie/502 block.

BTW, PM coming shortly.

I've heard anywhere from 557 to 598...and neither is a stretch for those factory Ford blocks...he simply says &quot;500+&quot;...whatever it is, it's making some steam to go 9.84 @ 139.82!

The FAST engine block rule seems a bit cloudy to me some days, as to whether the old 502 block is legal...

<span style="font-style: italic">2.01 Engine block must appear to be a correct* original block and it must be an original vintage OEM or vintage OEM replacement of the same engine family and exterior size and must be made from the same material as the correct* original block. Also, a new OEM replacement block is allowed only if it duplicates a legal vintage block in design, material, appearance, bore size and performance. No aftermarket blocks are allowed. Replacement OEM blocks that have raised decks, raised cam or bigger bores are not allowed. Block casting number does not have to be correct*. No aftermarket blocks allowed.

For example:
a. A correct* 400 cid block could be replaced with a vintage, OEM 455 block, if it appears externally correct*, and is made from the correct* material.
b. A correct* Mopar 340 could use a 318, 340 or a 360 block, if it appears externally correct*, and is made from the correct* material.
c. A correct* 327 Chevy can use a 350 or 400 block, if it appears externally correct*, and is made from the correct* material.
d. Mopar Hemi standard replacement block is allowed, but a Siamese bore Mega block is not.
Only early Hemi restoration blocks are allowed. For clarification, Email Dave Dudek @ [email protected].
e. GM ZL1 replacement block # 3946053 is allowed.</span>

I'm just not sure how big &amp; reliable I could go with my '70 512 block...engine guy says 540-ish?

Rob;

The way I read those rules, an A460, Bowtie/502 or new Siamese Mopar Race Hemi block is illegal due to the larger bore capability over &quot;production&quot; passenger car/truck blocks.

Given the newer technological advancements in sleeving blocks, one tends to wonder if those rules do anything more than jack up the cost of achieving a 4.500+ bore more than necessary(?). [img]<<GRAEMLIN_URL>>/dunno.gif[/img]

As far as how big you can go with an OEM BBC block, check your PM's.

Back in 59-60 I remember a magazine article where they bored a small block till the deck was open (no cylinder walls left) from one end to the other.... they then ground flats in the side of sleeves, pressed them in and furnace brazed the whole affair. In effect, they made a siamesed block long before they were factory available. Just depends on how much you are willing to spend and how competent your machinist is that limits what can be done.
