I have been trying to search but have had no luck,
I have just purchased a uc with a red 202 engine number starts with VL, The guy i brought it off believes it has a cam, spec ?,
I am going to use the car for Autocross and the odd short rally, now i want to know what performance upgrades i should do, i has a 4 speed MC6 manual, apart from cam, extractors and electric ignition everything else is standard as far as i know.
I am in the western side of melb
any suggestions would be great, i am tossing up between a 350 holley or su's also a yella terra head.
202 Performance upgrades

Get the head that Stedz_lc has for sale for $300. (In Eastern Suburbs but worth the travel)
Then get some kinda aftermarket 9-Port manifold and a decent carbie setup for it. WW Stromberg for mildish but much better than stock, Varijet for economy and similar performance, triples for more performance and worse economy etc.
Lots of options...

With an engine number prefix of VL I think you may have a 202 blue motor out of a early commodore. An easy check to see if it is really a blue motor in disguise is the capacity of the motor is written on the side in metric (3.3) red motors have the displacement in cubic inch (202).
If you've got a blue motor and want to stick with it you have a 12 port head and may require some different performance orientated equipment to the red. If you have a blue motor I would recommend a fuel injected motor borrowing some of the gear from a VK 202... Expensive way to go about it though.
On a side note blue motors were built to adhere to ADR27C, therefore to be 100% legal continuing compliance with this standard must be maintained (ruling out things like 350 holleys for all intents and purposes), most people however don't care and most don't get caught.
If I have made any mistakes anyone please feel free to correct me.
Good luck

of course it has a cam...if it didn't then the bloody valves wouldn't open now would they??The guy i brought it off believes it has a cam
now as for 9 port and 12 port...once you have seen one of each it is quite easy but rather hard to explain without pics if you can post a good pic of your engine from the manifold side I (and probably quite a few others on here) can tell you straight away...cheers shane

Hey Danny, to tell the difference between a 9 and a 12 port head simply look at the ports, you will see 6 exhaust ports on both heads but on a red motor there are only 3 inlet ports (1 port feeds 2 cylinders) which will have a post going through the middle of the port for the head bolt. On a blue motor the inlet ports are sperate for each cylinder so you should count 6 seperate inlet ports.
Lots of things you can do to get this thing hammering, first things first, how much $$ do you want to spend????
My blue 202 runs mid 13s down the quater, and theres another guy on here who has put his 202 into the 12's....
Cheers

that is the obvious way but if you dont want to take ya manifolds off just post pic and those of us who know will tell youHey Danny, to tell the difference between a 9 and a 12 port head simply look at the ports, you will see 6 exhaust ports on both heads but on a red motor there are only 3 inlet ports (1 port feeds 2 cylinders) which will have a post going through the middle of the port for the head bolt.

Look at the driver's side of the head at the front (spark plug #1 area) does it have three threaded holes pointing out towards the side of the car in the pattern of:how can i tell a 9port head from a 12 port head
o o

Or does is it just plain? If it has the holes, it's blue/black. If it's plain, it's red.

Sorry about this, STEDZ! empty your in box.
A 2 barrell Holley or Stromberg will out perform a Varajet if tuned properly.
With the Varajet you will have optional economy.
Depends on your right foot.

Hey Danny!
To get going and not breaking the budget, id suggest starting out with an electronic ignition mdule conversion from a later model commodore, nice cheap bang for buck and will also help a little on the fuel economy. Most definately yt heads can be picked up under the 400 mark with needing hardly any work to be done except bolt them on. So if your pretty handy with the spanner and have got a manual, then you will certainly notice a major increase in perofrmance from this.
A ww strommy on a redline or similar manifold will help, but once you start to get serious, efi is the way to go. Ive also heard/read somewhere that the redline manifolds cause 1,2 5,6 cylinders to run lean in comparison to 3,4 due to the varied lengths of it. Most certainly its not the most ideal manifold for high high performance in the long run.
Also if your looking to hit the track a fair bit, you will find some great results from working on brake and suspension upgrades. Probably make things a lot more fun and competitive on the track.

Yep. Blue/Black manifold has superior distribution to cylinders.Ive also heard/read somewhere that the redline manifolds cause 1,2 5,6 cylinders to run lean in comparison to 3,4 due to the varied lengths of it. Most certainly its not the most ideal manifold for high high performance in the long run.
Maybe consider a Blue/Black head? Again bolt on performance.
Maybe this is still for sale? And cheap!
