must get on with Dart !!!!

[MilesnMiles]

Erm, ok. That's the spec I've had on my 360 and 340 motors but with the higher compression pistons. Only concern would be low cylinder pressure Those are high flow heads and with the Air Gap might leave you struggling at lower revs. That said, it's a four speed isn't it? If so, you should be able to stir it up ok.
Keep looking for that 360. Then you will park the Mustang permanently

Miles, its a poorly 727. clutches are slipping. I have imported an Alto upgrade/overhaul kit, and a kit to modify the workings of the valve body.
I need to rebuild it, and I need to import a, 2500-2800 stall coverter.
that should be Ok.
I 'll then have a auto box and disc/locker equipped rear axle capable of taking more power than the 318 can put out, and if I find I want more power later on , the auto and axle are up to taking more power, and I can stop it as wel, which is always handy
The Dart is a keeper,but I don't want to sink thousands of pounds it it

Keep the Muzzy.
For me life is short , and I enjoy a daily yank v8 rumble before and after work.
Its a work horse with a bonus in my mind.
BUT. Driving a classic mope is what really blows my hair back !!!!
Owning and driving one daily has by no means " got in the way " of getting the Coronet back on the road.
Crap out of my control keeps it in the garage !!!!

[Bozwell]

Yep might be a bit optimistic
I won't be changing the pistons, or decking the block, .

what about a crank regrind but offset the grind to put the pistons further up the bore (will need to make sure there is no lip at the top due to wear). should be able to work out if a +10 or +20 offset grind will increase the compression by how much (and slightly increase CuIns)?

anyone tried that?

[Blue]

That's they way it used to be done before stroker cranks were readily available. It can get expensive, offset grinding the crank while keeping the stock rods would mean welding up the other side of the throw before grinding. I think a 327 chevy rod has a smaller journal and can be used but I doubt it's just a straight bolt in. Unless you can do it yourself, machining costs tend to kill this kind of trickery. I'm sure you could get 350hp to of a 318 but you'd need good compression and it would be at high RPM with not much low end torque.

Why not leave the internals & bolt on a Procharger?
.......your 350hp goal will be at your rear tyres easy

I like that idea, and had consider turbo charging.but its time consuming work making up the manifold ect. and costly
How much is a pro charger kit ? probably out of my pricerange.
Can you pressurise 4v carbs ?

Mopar Muscle did a Valliant a little while back, I'm sure if you google it entry of info will come up.
Check out Prochargers website & also Paxton.

Mild boost on a stout short block shouldn't be any more expensive than trick pistons, heads etc.
They even come up used.

[Bozwell]

It can get expensive, offset grinding the crank while keeping the stock rods would mean welding up the other side of the throw before grinding. .

if offset grinding by only about 20 thou it should mean you will not need to build up the crank though. offset grind and use +20 thou bearings. it's not an exercise in increasing the stroke but lifting the pistons nearer to the deck height to increase compression. +40 is the usual max oversize bearing size so in theory if the piston is 60 thou down the bore at TDC then offset grind by 40 thou would see the piston 20 thou down the bore. shouldn't cost anymore than a normal crank grind?

[MilesnMiles]

...or just drop some KB Pistons in and raise that compression to where it should be

[Bozwell]

[MilesnMiles]

Yes, I know. But it's still the easiest option to raise cylinder pressure I'm sure.
Anyway, let us know what you do decide on, Johnny.

I wonder how true the HP figures are,yank dyno readings are a bit like US gallons,not quite the real thing
