I think aussiespeed has been recommended better than anything on here more than a million times

My bad

Correct me if I'm wrong but your extractors look to be made of mild steel with a HPC coating not stainless so any works you need to do to them will be much easier to source the right size pipe

I'd be using king bearings tbh

Had the same issue, brought a new set of bolts same as u and snapped 2 out of the packet, threw them in the bin and ordered studs, Havnt had an issue since, I thought I had been setting the torque wrong aswel but I just thought the quality of the bolts nowadays are crap

Are any of fan blades behind the alternator pulley bent and rubbing the alternator body

Doesn't sound like a bearing noise at all, sounds like something is rubbing/hitting somewhere

Pull your water pump off mate and check to make sure the blades arnt chopping into the outer sleeve of no.1 bore, I've seen it happen before

God no, like u said bruz all he seen was dollar signs

Hehehe much better bro!!!

It's all been said and done before but please stop making out its all your own idea, it happens way too much on this forum

Basic knowledge that's been around for nearly half a century on these engines yet we all think we've just invented the wheel

Ando the head flow figures I posted previously compared to the combo on this thread were improved again overall, testing wasn't a half arse job and the ultraflow at the time fixed the low temp rich fuel burn in no.1 and 6 cyl, no testing has been done like ures with the new manifold and none is needed as ure result prove

Mark u are the leader in the development of the top performing engines in this country and in the areas u touch overseas, what u have developed and put a huge amount of work into with what you have available in today's market now covers all boundaries of 250 performance, u said it, as do with many others that found out the hard way time and time again proves flow benches only show numbers and figures and sometimes end up with disappointing figures, why work a manifold when there's already 1 that's made for the job, I love tinkering and these threads are furthering every1s interests in these motors, keep pushing the boundarys I say....

Ando testing proved with the extra volume of meth added to a big plenum lost its airspeed and reduced the correct air/fuel mix needed for a clean burn, whilst it was on pump fuel with the lower fuel volume it tendered to keep a good mix of air/fuel ratio without separating, even flow runners works fantastic with a sided raft webber setup and thats what they were designed for but trying to emulate that with a 2barrel meth carb setup creates issues e.g. Slower Pockets of dead air, Clevo knows what he's doin as do u, just don't go crazy like the rest of the chev lovers do....
