350 holley fuel rich running issue

for some reason my holley 350 is leaking fuel in the vacuum chamber behind the power valve making my car run really rich, but still pretty good.
I have a lumpy cam in it, with 107 lobe sep and 287 #50 duration with 430 valve lift.
the vacuum is at 13inch which is normal for a hot motor to have low vacuum like that, so ive got currently a 7.5 power valve.
at first I thought the power valve that was in it was faulty so I replaced it.

202 Blue extractor leak.

Hi guys, I’ve been batltling a extractor leak on my 202, I’ve tried everything to fix it but can’t get it to seal, the manifold and extractors don’t sit flush so the previous owners cut the outer studs etc to get it right although now I can’t figure what goes where.

It’s running a Redline Torker 2 manifold and a unbranded set of exrtractors.

Changing engine mounts ej holden

Thinking of changing my engine mounts on my ej, have changed the front before but never the rear.

Can I change the rear ones easy enough without needing to lift the engine.I haven't got equipment for lifting it, but was wondering if it is possible to jack it up from underneath and use blocks of wood to protect the sump.

Anyone know the process?

Testbench 202 not starting. Ignition issue/No spark.

Hi fellas.
I've just setup a 202 on a testbench frame and looking to get this thing firing up. For whatever reason I've got no spark. I've even changed distributors and coils from a running vehicle and still no change.

I've hooked up the +ve from the battery terminal to the +ve of the coil, then have a +ve wire going to the +ve of the distributor.

On the negative side, I've got from the -ve of the battery terminal to the -ve of the coil and then to the -ve of the distributor.

Holly Sniper EFI 2bbl or 4bbl ???

I am trying to decide on 2 barrel 2300 or 4 barrel Holly Sniper EFI for my EH.

I have a reasonably worked 202 blue motor.
The head is pretty good it used to be on a speedway car (red block with a balanced bottom end and produce power to +7000rpm.
The bottom end is a reco blue 202 with standard bore.

I currently have 465 holly on it with a Cain manifold that I modified to fit the blue head.

What I want to know is should I run the 2bbl system on the 4bbl manifold with an adapter or put a blue motor manifold back on there with a 350 holly adapter plate?

Holden Red HP Block Identification?

Hi all.
I've been given an old holden red motor today, and on one side it's stamped HP. On the other side the engine number is M101XXX. Inside the bore, is't got repco flat-top pistons "RA2027 STD". I'd assume that the motor's had a re-bore to 202 specs?, but what size would have it been as factory? what was it originally out of? and what's its likely displacement?

Cheers!

rebuild a 253 or replace it - What do ya reckon and how much $$

Hi Guys, 1st time poster .... i have just purchased off a mate a 73 HQ UTE with a 253V8 in it .. It hasn't been driven or started in over 2 years ... and its on gas/petrol as well ...although i will get rid of the gas crap... It does leak some oil but was running good before he parked it in his shed, and let the rego run out ... My questions are 1) What would it cost ( APPROX) to rebuild the engine and work it a bit ... Give it a lumpy cam and make it sound nice at idle ...

Genuine original Carby HZ 253

Does anybody know what is the correct number a HZ 253 Auto should have for a Carby. I am currently looking at replacing mine, the number on mine is a 23-1111. Is that the original number that the car should have or is there other options?

It’s a 2 barrel Stromberg.

Build date on tag: 09-78

Engine date stamp: 6Dx (either a 6 or 8, need to remove oil filter)

Removing 202 from WB

G'day Brainstrust
I'm about to remove the 202 from my WB tunna. My query is that the motor is connected to the aussie 4speed with the bench seat shifter, so is it necessary to remove the whole shifter assembly with linkages to get the engine out with box attached or can the shifter come through the trans tunnel hole with a bit of wriggling and jacking up the front of the car? Having never done this before with a aussie 4speed box a bit of sage advice would be greatly appreciated.
Cheers all
Al
