Weak VB!

[kman31]

Hey people, Im new here!

The names kyle and ive had my VB for about a year, i bought it for $1000 with 115,000 on the clock, some paintwork damage, and the 2.85lt, 179 motor i think it is.

After i pay a few bills, im considering making it go faster to tell those people who say "get a f*rd" where to go.

I'd love a v8, but im quite keen on keeping the engine thats in it at the moment, and seeing what i can get out of it.

Any ideas on what i could do to it would be awesome

Cheers guys

Well the motor isn't a 179 but a 173.I don't how a 350 holley would go but a port and polish of the head would make it go a little better.A 2 inch sports zorst with extractors too.But first whats your budget?.

I'd say take it back to the pub, maybe you got a bad batch and they should exchange it for a new carton for you. Best of luck

hehehehehehe

haha, i knew someone was gonna say something with a beer reference :P

[kman31]

budget - not really caring about that at the moment, but after ive payed a few bills then i can splash my cash.
I was wanting to paint it green and turn the boot into an esky, but decided engine mods would be nicer!

Pity they didnt call it a Holden Carlton Draught, then i might be into it more
Cheers guys

I don't how a 350 holley would go but a port and polish of the head would make it go a little better.

A 350 Holley is overkill on Holden 6s unless you've got (at least) a decent cam.

On an otherwise stock engine, a better (and cheaper) option would be a 2 barrel Strommy off a red 4.2 from around the same era.

Some other options:

1. A HEI dizzy off a VC/VH.

2. If its auto - convert it to manual with a 5 speed box from a Toyota Supra. A short-ish diff ratio will help a lot too (say between 3.45:1 and 3.7:1). 5th on the Supra box is overdrive, so you shouldn't have any issues with fuel economy on the highway. If you buy most of the parts from a wrecker, you should be able to do this fairly cheaply - provided you do most of the work yourself.

3. If it has aircon, ditch it because it probably doesn't work anyway and only puts extra load on the engine.

Would you seriously ditch aircon for a few extra kw?? I'd rather be comfortable.

Fair enough. Its a VB though, so it probably doesn't work anyway. IMO Commodore aircon was useless up to VL.

VL aircon is good 'cause its Nippon Denso which is one of the (if not the) best.

how do u go about fitting a 2 barrel strommie of a 253 onto a red 202. Adapter plate or different manifold? and also what about linkages?

New manifold. These people should be able to help you with linkages too:

as far as i know the only way to do this is to find an inlet manifold from a 186S motor, as this motor had the 2 barrel as std. And i don't think redline make a manifold to fit. Either that or i will make up an adapter plate for the 2 barrel holley manifold i have.

The 186S manifold will make a post 1976 car unroadworthy.

Redline make two-barrel manifolds for Holden Red 6s.

[bassfiend]

the manifolds they make are only for a holley 2 barrel tho, if they do make one to suit to 186s carb i have never seen one or heard of it and it is no longer on the site. Unless it will fit the holley 2 brl manifold?????

Ring 'em up and ask.

And the 186S carb isn't the one you need. You need the carb from a post 1976 253 V8 (either Kingswood or Commodore will do.)

The reason being that post '76 have emissions controls.

a 179 (or 173) in a commy?? wow..... rip it out, give it to someone you dont like, and throw a 3.3 liter in her with a yellla terra head..... or even keep the 173 head and slip that onto the 3.3..when doing the timing, advance it as much as it will let you.... see how that goes......and 149 heads are awesome on red, blue and black strait 6's......

[clixanup]

and 149 heads are awesome on red, blue and black strait 6's......

But the Blue & Black motors have a different water jacket design to Red motors, so this makes Red and Blue/Black heads non-interchangeable doesn't it?

Re: the 149 head: does it increase the compression?

[bassfiend]

you have to drill a few holes to fit the blue head to the red motor

Re: the 149 head: does it increase the compression?

it surely does, matey..... the cavities the valve seats live in ( on the 149 head) are smaller than the other heads...therefore, less space..more compression.......didnt know there was a difference between the colored motors.... i always had red motors, and have always put on heads from 149;s, 173's. etc onto 202's....until the last engine exchange on the HJ,when i put a souped up black 3.3 vb commo motor into her....bloody thing flew then , i can tell you....
oh yea...the harmonic balancer on strait sixes is rarely in line, like it should be...so when you tune it, if you use a timing light, you probly wont get the right settings..i always did it with the light, then advanced it about 6-8 deg....... the mother flew then!!!!!
