Those have to be photos of their cast gears even though it says melo, because they look so crappy . If that's really their melo gear, I wouldn't use it.

Ok, I just looked and they look the same as the MSD gear so those are their melonized ones.

Mallory have been selling most distributors with Melo gears for a couple of years. I see Crane make Holden small block gear as well which is handy to know. A mate wants to build a Blue meanie VK commodore with a 355, & injected VN heads

VN heads ,thought you knew everything ,google is your friend

VN is the model ID for a Holden commodore, it was the first year of high port heads on the fuel injected 308 small block. They are pretty sort after for 308 engines work pretty well, kind of hard to come by, other than that the early 70's pre smog heads are the next best fitted with Torana L34 valves, which is the same as the Formula 5000 open wheel Holden engines used. A 308 is not like an SBC, it kind of a cross between all GM small blocks

So much to take in...

Comparing the current cam with say the suggested Comp cam, would it be more than likely they would have used stiffer springs?

Everything else seems to be high dollar parts so i cant see logic in scrimping on the springs etc.

GLENN 70 · « **Reply #135 on:** February 23, 2016, 11:22:05 pm »

No not likely, but you have to get the cam specs and spring specs for both cams . You might have to get the installed hight changed . This is very very important .

Ffs,

It took me over 3 weeks to just get that cam info from them

GLENN 70 · « **Reply #138 on:** February 23, 2016, 11:24:55 pm »

Its worth a few bucks now . The VN group A engine was a big deal for holden .

GLENN 70 · « **Reply #139 on:** February 23, 2016, 11:26:12 pm »

If you have the cam number you can find the spring specs without talking to them . The valve spring pressures and installed hight have to be checked and correct .

barnett468 · « **Reply #140 on:** February 24, 2016, 05:05:09 am »

fitzy . read my posts . i have your cam specs . i know what spring pressures the new cam needs . both cams can use the same springs . . your engine ran fine before . your engine is still new so your springs should be fine but ask them if they used their own springs or bought the heads assembled and tell us what they say . i have the spring rate for the assembled heads . they have two different rates . if your heads came with the lighter rate springs, it probably wouldn't rev past 5500 rpm and would miss and pop . do not loose sleep over the springs, you have enough going on . this should be fun instead of being stressful.

Unfortunately not in this case . Snausage has 3 optional lifts for the same cam number . The cams have a serial number that identifies them and only Snausage knows what the serial number means, however, the clowns sent Fitzy the lift for his cam yesterday so we now have all that info.

The cam I suggested has around .020" more lift and a slightly steeper ramp, so it is not dramatically different.

All I want now is a photo of his Snausage so I can see if it is steel or not .

barnett468 · « **Reply #142 on:** February 24, 2016, 09:57:27 am »

.
Check the spring diameter . If the idiots bought the heads assembled and you have the smaller springs, you are screwed because they are even too light for your Snausage cam.

If they bought them assembled and you have the bigger springs, they are perfect for your app and could support even a slightly bigger cam.

diameter 1.437 . closed 130 @ 1.800 . open 330 @ 1.25 . coil bind @ 1.08 . max lift 620

diameter 1.550 . closed 195 @ 1.900 . open 456 @ 1.25 . coil bind @ 1.08 . max lift 650

Ive had the morning of my life today, swear the gods hate me.

Mrs was on the way to the hospital. Rings and says the car has died, coughing, no power and just died. Now this is a 3 week old $90k 200 series Landcruiser.

Get there doesn't even look like starting, checked a few things. Then i get a really really bad feeling....

I ask "did you put fuel in on your way"

Her "yes"

Me " what fuel ?"

Her " just what i normally put in "

I keep all reciepts for tax purposes and there we have it big ol tank of 98 OCTANE !!!!!!

So its on a flatbed back to Toyota, and im prety sure there is no warranty for stupidity.

No wonder a man drinks..

So what is wrong with using 98 octane....unless it's a diesel.

Look on the bright side, with your newly acquired mechanical skills, you should easily be able to replace the engine .
