302 Rebuild

A wise man once said to me:-

"The crank does not know what brand is on the rocker covers"

Tomcat, stick a stock 351 in your car and I will be happy to race against my stock 350........

I think Carroll Shelby proved all that long ago ...

Until an LS engined cobra takes fastest lap @ the nationals then the windsors have the bragging rights... Gary Walthers 1:03 was pretty quick.. Ok so it's a 6 litre dart blocked V8 supercar engine but it's still ford based ....
On the other side I use a VE SS sportwagon to tow so I'm also an LS engine fan...

There is no doubt that windsor engines can produce some awesome power, but for big bucks.
Very few engines could match a LS engine power for dollar. (OK Scotty quad cams too)

The fact that Waz and Mizzi have both bought LS engines is testament to that!

just a bit of good banter boys but, waz can confirm that his crate ls7 cost over $20000, you could build a 427 windsor for around that,give or take, so thats hardly HALF price. beejay im not about to destroke my engine then drive south to race you, so how about this, you would probably like more power so why dont you stick your hand in your pocket, stroke your ls to 6.3ltr same as mine, stick some 3.6 gears in the bum and put in down the 400, that would be a fair comparison,then show us your time slip. then we will see if youre faster for half the price

Tomcat,
A stroker LS3 taken out to 400+ci can be had for as little as $7700US
While a LS7 would be great, the are definitly big bickies!

Ash,

Since when does power equal fast laps.......!

Tomcat,

I bet a stock LS3 with a cam would make similar power to your engine, and be under $10K. Ugly engines - yes. Bang for buck - awesome.

HSV300.

Very sweet motor!

beejay, whats a stock ls3 make 300kw max, probably not even that, that must be some cam youre going to stick in it to get over another 100kw from a stock engine just to get close to me and im only running a '' touring '' cam, if i was to stick a race bump stick in it as you would have to do, there would be no comparsion, so i bet thats wishfull thinking on your part

I reckon argueing with the Pope about the theory of evolution would be kind of like this.

We are taking the side of EVOLUTION Tomcat

Ben,

Couldn't agree with you more, up until Xmas I was running with about 280 rwhp which is well short of even the most basic LS engine. That 280 was good enough for a 1:08.0 @ the Nats on Friday practice last year. All about getting drive out of the corners, low down torque. Doesn't matter if it's got 500 Hp & no low down torque then it will underperform. Drags are a different matter totally. I had a vu SS ute that made 298 rwhp but had nothing under 4000 rpm. No drive out of corners unless you came out @ 4000 rpm.
Love the banter boys!

Tomcat, love your passion.

Power to weight is what its all about.

An Ls engine is like buying wine in a box. Yes it is cheaper per litre, its packaging is light weight, no need for a cork screw, it may even taste like wine.
A windsor is like a bottle of Penfolds Grange, rediculously expensive, comes in a heavy glass bottle, care must be taken with its storage, the cork must be carefully removed. The Taste will be rewarding and in your memory forever.

Now if you were offered a glass of each which one will you take??

Windsor sure look better, I'm putting this stroker in my Mustang

we certainly dont want to do any comparisions there do we.
GAV point taken, but you can also buy a coyote 400hp crate engine,for less than $7000 us that you can now stroke to a 351 with all the latest technology.
my point being, youre gm based products are not half the price for crate engines or worked performance engines otherwise ford would be bankrupt long ago which is where gm finds itself now, bankrupt and broke

[Merv and Sharon]

How's the re-build going Geoff? Did you solve the mystery of the pitted piston?

[Gav]

Bet a coyote would spank your stroker Tomcat

well if it did, it would simply annialiate your ls gav, which just destroyed your own original statements about how much more hp for half price your ls engines make

[Beejay]

Anyone managed to fit one of those Coyote engines into anything here in Oz yet?

HSV300, That motor is a thing of beauty.

Had some time today (its the weekend) to do a little more work on the engine.

With the damage to the top of the No.2 piston, I decided to remove the piston and check (a) for damage to the sides of the piston (b) damage to the big end - bearing or journal. Thankfully, the damage appears to be confined to the top of the piston and the mating surface of the head (as in the photos above). Here is the side of the piston:



There was also no visible damage to the bearing or the crankshaft journal for the No.2 big end.

With all this in mind, I am happy to agree with the two earlier conclusions (thanks boxhead and blykins), something has made its way into the combustion chamber and caused the imprints on the piston and head before being exhausted.

So with one piston out, it was little effort to remove the others and the crankshaft.



With all this apart, I measured the crankshaft bearing journals (connecting rod and main), the pistons and the bores and I am very pleased with the results. All were well within specifications for both size and taper.

Before removing the pistons and crankshaft, I also checked the big end bearing play and the crankshaft end play - again, both well within spec. All corresponding measurements were within tenths of thou of each other.

Next, I will be taking the block to be honed and will be replacing the bearings and the rings before it all starts putting itself back together.

Cheers

I think while youve got the engine stripped down this far I would be boring it and throwing in a new set of pistons to match those new heads....
Take one of the old rings off and put it in the bottom of the bore measure the end gap....now put the ring in the top of the bore and measure the end gap ....I would bore it....anyway thats my two bobs worth...
