i just put a cam in mine and made a big difference! well worth the effort, unless u bolt a supercharger on it or stroke it it would be the best mod u could do to it. depending on the size of cam u will need a decent exhaust, cai, maybe shave the heads and get a dyno tune to get the best out of it.

check your total timing thats more important

hi will a vt 195kw hsv memcal work in a 1999 vs series 3 ss ute? cheers

dont have any error codes so i mite change sensor anyway! is there an easy way to check 4 leaky injectors?

hi i have vs series 3 5L that starts fine when warm but struggles to start when cold in the last week or two. do these motors have temp sensors that would effect cold start ups if buggerd or could it be something else causing it to struggle to start when cold? cheers

id go the come cam if u want a strip animal the 286 would be a btr street cam in a 355! i would get your vt heads ported u can get sum good hp out of them without costing heaps and they have smaller combustion chambers than vn heads which will help get your comp up abit, id be looking at 10.5-11...

make sure they are the same heat range, they could be too cold????

dont ya mean well hung? lol

u will need to shave about 60th off ya heads to get close to 9.5 to 1 comp or 40th and a thin head gasket and thats if u have zero deck height, the ferther down the bores the pistons r at tdc the less comp u will have and u mite have to slot the bolt holes in manifold they genaraly still line up...

bout the only thing that is the same is the valve springs and lifters.

hi are the v6, 5l and ls1 mafs the same?

i guessed it about 10cc so i wasnt far away! cheers

hi dose anyone know what the volume of the piston dish of an injected 304 piston is?

did you even read this thread? lol

cant comfirm but try fitting tailshaft yoke into trimatic and see if it fits first!

if u build up a motor along the lines of a commodore cup engine u wouldnt go to far wrong! ive just built a 253 but havnt had it on the dyno yet but the commodore cup engines make about 350hp with a fairly small cam but they r now using yella terra alloy heads that u can buy now which would be a...

no not if u already have a set of heads u can do up! 400 bucks would be a good start on them! ports are the same the have just been machine for the bigger valves.

unless u have a big cam and chasing big hp its probly a waiste of money. if its a standard motor with a baby cam just a good valve job and get them machined is all that is needed as 304 heads flow heaps anyway.

no formula just start with standard gap bout 1mm i think and u can make it a bit more and see what happens. 1mm-1.2mm is pretty goood if u have a realy good ignition u mite get away with 1.5mm.

just buy a new dominator if u have a good little engine with a nice cam it will be worth it!

the early holleys have a little ball under accellarator pump diaphram thats ment to let fuel in but stop it going out when u pump the throttle. if carby has been sitting for awhile the sometime get a white powder or corrosion which makes them not seat or seal properly! undo the four screws under...

could even be a broken engine mount! a good sign is that when u accelarate hard the gear stick will try and hit u in the knee!

if they bolt up to ya flex plate and locates in the crank it should b ok! ive herd people using 4cly convertors in 6cly. mite be able to bolt a 4cyl to v8 to give u a bit more stall? either way they wont be as good or efficent as a brand new dominator!

5l trimatics have an extra clutch plate. dont know how to tell without pulling them apart. u would think they would have a different part number???

used to have a set on my 202 years ago! all i can suggest is that make sure all the carbs r open the same amount at idle and the same amount at wot! bit of an art on its own workn out the linkages, make sure they r squiting the same amount of fuel with the accelarator pumps, play with the idle...

yeah buy it and then after 100,000ks of spinning ya motor hard u can pull ya motor down and tell us how good they r!

thought bout buying 1 but didnt! i think they r a good idea, bit cheaper than setting up a 4 bolt conversion! i didnt think they came with studs u have to use sb chev ones they r a bit longer!

dirt,dust and crap kills engines! id be pulling her apart and giving it a good scrub, unless its a old shitter thats guna blow up anyway!

yeah and its fairly easy to work out the people who know nothing!

have alook under the rocker covers and find a part number and let me know and i can find out what heads u have! sum 402s had he the same head as a 454 depend on the year!

big block chevs r awesome all commodores should of come starndard with them!!! what heads do u have now? if they r oval port with the small combustin chambers mite be worth giving them a bit of porting! the problem with 454 heads they will have bigger combustion chambers and u will loose alot...

750dp holley

most likely blocked radiator! tend to block up over time and if ever used stop leak block up even quicker

when pulling pistons out u should always number your rods and end caps in there firing order so that they never get mixed up and u will know what piston went in each cylinder! but if u have messed up the end caps u will have to sort that out first!

thanks for the info guys will chase them up! cheers

have u changed your engine oil lately?

vs series 3 roller cam engine r the same heads as vt if any1 has a set of them

try another 5-10 psi in them not all tyres r the same and c if that makes an inprovement! if your suspension and wheel allignment is a1 and nothing helps u may just have a **** set of tyres!

there was a good add on ebay telln people how good those heads are! nothing wrong with factory heads well worth spending a few bucks on!
