That would be a dream engine in my D.

you'll be lucky to hit 400hp unless you want to rev it past the danger zone..... 6,000 rpm

6000 = danger zone?

Personally I'd go for the 331 over a 347, taller piston leads to longer engine life, problem is with a roller block if you start making more than 550 HP or want to spin it past 7000 rpm most factory blocks won't last before long before they call it quits although occasionally you will find one that will, what sort of power are you chasing?<br />

I think I will need to keep the factory block as an after market one will suck half my budget, so that limits power, not keen on 347 due to rod angle at bottom of stroke, so 331 would be the most and to get over 500 HP with those cubes makes it pretty angry. I think 450 would be enough in a light xd.

ive just bought a 302 windsor for mine ,ive had alot of clevos, spent big money on them ,and they go hard ,but there fooking heavy ,a little windsor is much lighter and parts are more readily available

 

gt40 heads add afew ponies

I still have the au gt40p heads sitting in the shed, the first mod was the alloy edlebrock heads.

This weighs less than a cast iron head xflow with all the alloy bits.

Right, I have thought about doing a Windsor thread for a bit, and now that I actually have something to write about its a good time.

There aren't to many X series (XD- XF) on here that are running Windsor's, that I have read about. 

I have an AU3 XR 302 roller block std stroke, 60cc edlebrock alloy heads, rpm manifold, 600cfm quick fuel carb, hurricane headers, Mallory ignition, F303 cam, roller rockers, Gilmour drives, zero decked block and all balanced, apart from block, crank and rods, its all brand new.

Since reading other threads such as Slydogs and pro250s with the NA and boost builds, I feel that I need to redo my combo.

I have looked at the 331 stroker, going to bigger AFR 185 heads, more comp, cam and induction OR keeping the 302 and putting boost through it and converting back to EFI as I still have all the bits n pieces.

Potential budget of an extra 5k.

Any thoughts.

ok I aint buying one now not what they told me

Hey mate, what were you told about the motor?

Thought so, I think the "racing " no name parts give it away.

My grandfather always said if you want your horse to run faster, you have to feed it more.

So when I buy parts, I look at price and think how long is this going to last for what I want it to do.

Companies like Procomp try to polish a turd, but end up just rolling it in glitter, end of the day its still shit! But guys time after time buy these cheap products, and when they break they complain.....

Keep up the good work Aussiespeed.

That is the same company jamie247 is talking about in the 393 Cleveland thread.

The thing I don't like is how the advert doesn't say what the brand of parts are, just "racing hydraulic lifters", could be procomp? Get my drift?

In saying that a mate of mine purchased a chev 350 crate motor, thrashes the crap out of it, years later still going strong.

Yes get the 8.5inch with the 5inch back space, I learnt the hard way and got the 3.375 inch back space and they cant be used as the rim sticks out past the guard.

Ah yeah forgot to mention that, I have used an EA handbrake cable and used new brake lines.

Depends if you intend on running later model disk brakes?

I put an XG XR6 diff and brakes into my XD, the only issue was the spring saddle locating pin hole on the XG diff is 36mm, and the std XD one was 32mm, so I had some blocks made to lower it and locate the diff properly.

Went from 2.92 to 3.45.

I think you need to work out chamber volume first, if you take too much off it can affect the pushrod length. Might be easier to get smaller chambered head. I had this problem when ito went alloys on my windsor and I ended up zero decking the block.

Im a windsor fan, dont know why??? But most of the 393/408 stroker windsors around the 500 hundy all seem to run the airgap. Its only 1.25hp per cube, not a huge ask for these days.

The one I watch had better torque and peak HP, it was on a mild sbc though, around the 480hp

Hey mate, there are some good comparisons on YouTube with manifolds, one where an air gap with one inch spacer out performs a single plain on mild motor build.

Cheers guys, I will do this over the easter week end.

Hi guys, just got a new set of Hurrican headers for my windsor. They are coated with blue silvery paint that I assume will burn off quickly.

Any suggestions on what I can coat/paint them with that does not burn off?

Cheers
