3.2xs for drag racing?

**Chaz** · 04-14-2018, 08:32 AM

Gordon did that X block motor for Harry as well .
If I'm not mistaken , it was around 3.4 L .
The name of the Ign escapes me , but it was something like Digital Performance .
Harry told me it was a handful the one time I met him , really good people ..

I really like them Opti -""POPS""

Andy did one of the very first 15" XS's . He said something about the open exhaust , fuel system , lean burn .... anyway , I'm not a big fan of that deal . Lookin for gas mileage , buy a Honda step thru 90 .

Once ya relize that Joan Claycrook is no longer the EPA czar . You throw away that gas mileage *%^%$&* off of it and go back with something more conventional .

This way it won't death rattle the balance weight out of the crank ....

Not sure why just yet , but they been startin to show up a half a dozen at a time with the register split .

They use to put them in too loose and they would rotate . Now they go in tight and from what I hear and what I see ( lots of wall scaring ) Merc has taken up the practice of doing the "cold shove" to install sleeves ..

But look , them's some ed-ju-makated boys . They must be workin on a new "external firing cylinder" ...

There's a lot of silicon ( dark blotch's ) in the aluminum that makes for a easier to work with less porous , but weaker casting ... The modern age of throw away

The up-side ...

There is a billet 300x style reed adapter plate being cut ( first ones are done ) that will work with either the opti plenum on early twin computer , Motorola EFI , or OPTI blocks .

A new progressive slide that will not only work with the above adapter plate , but have an idle feature ( I wish I thought of it )

that will remove that dead hole /run away cylinder feeling that isolated independent runner intake systems have when used on a average Hi-perf motor .

If you throw the Pee-Wee Herman sleeves in the garbage can , and throw in a set of customs ...

The final bore of a 3.6L comes out to about the same diameter as a standard block with the sleeve out of it ..

Now if ya are going to just drag race one . Maybe run it on Alky , then there is no reason why you couldn't put a deck ring in there and a 4" piston ...

Oh what I would give to be a fly on the wall in your shop Chaz.

Yeah Allison's are a hand full to drive anyway, Can't imagine a very high torque motor on a light one doing a hole shot

Ought to name it Rock and Roll ,

be lot safer on a STV , lot less Pucker Factor for sure .

I found Andy Driver and his brother .

Only their hairdresser knows for sure

Need to tell Monty , he has hit a new LOW, working on Mercury 's

their is a cure for working on Mercury's

Electroshock therapy treatment! a ZAP here a ZAP their and he'll be OK.

and I thought he knew better?.

Is that a official Merc sleeve puller ?

Your AARP card is as old as the rest of ours ... you'd fit right in with the rest of us antique's ...

I think the statute of limitations is up on that one , but it never hurts to try .. LOL

Is that a official Merc sleeve puller ?

My son made it out of the scrap barrel almost a decade ago , thinking he was going to make two or three before he/we were happy with the best one . It's fugly , but works great ... ( can go from block to bench without dropping one on your lap , but release them in a couple of seconds ) ...

Use to be : Early , Late , 300x .

I feel like Joe Pesci in Casino on a losing streak @ the Blackjack table .. I had no idea there are so many different port combination's of 250xs sleeves ...

The up side is ... I'll have one of everything one the shelf ..

I wonder why the difference , I'm new to these things , going to sell a 260 drop on powerhead and start the big block thing, I' m sure I've got the dome pistons last year of the 140 psi motors , this will be fun.

It's like the factory had a stockpile of slightly different sleeves they needed to use up that found their way in the 225-250 Opti's . I spoke to Jeff @ Advance Sleeve again yesterday , he is definitely putting some effort in updating his Opti / year-mid year change and change again

/ port ID / part # program ..

Moon crater pistons .......

pull the sleeves and nicasil the block?
EDIT

**CUDA** · 04-17-2018, 10:12 AM

Can you nicasil Steel?

What would be the gain ?

The 250xs will never be a high RPM motor sooo?

The purpose of the coating is to allow an aluminum sleeve to sustain the load of the piston and rings. The advantage is that the aluminum transfers heat quicker than steel, and there are no thermal expansion issues.

It is possible to chrome a steel cylinder and it is done on very large and expensive industrial engines. In these applications the rings are plain cast iron. The rings wear faster than the bore so essentially on an overhaul only he rings need to be replaced.

To add a similar longevity to a non plated iron cylinder typically chrome plated rings are used. These however will wear on the cylinder wall and eventually need to be bored, etc. Chrome rings are also difficult to “seat.” Typically iron or “moly” coated rings are used as a good compromise of wear and longevity in an iron/steel bore.

sorry, clearer now

Nitro that brings up the question , were the old 1979 200 Black Max a steel bore chromed cyl?

Or were they aluminum chromed ?

I remember their was some special break procedure for my chrome bore in for the old days?

To think that was only 39 years ago,

They were aluminum chromed. Over the years as plating technology advanced the process changed from chrome to Nicasil, NiCom, etc. All are applied to an aluminum sleeve though.

The reason I brought up the 250 was in response to " 2jz " . I have one of his blocks here that has gone thru the "mid-years sleeve shuffle" .

The powerhouse 300xs's all use the "1194" sleeve with the non-symmetrical ex port walls .

Plated steel sleeves ! All the weight of steel , plus the idiosyncrasies of NIC and much , much , more ....

Tell em ................. Power sent ya ....
