I fit my carbs with the primaries at the towards the front of the engine. This leaves the cable on the passenger side. On the front of the carb you will see two small vac ports / pipes. Look carefully and you will see that one port is lower than the other. The lower port gives max vac at idle with t...

Real Steel sell a generic throttle cable kit with a bracket that bolts onto the carb to hold the throttle cable in place. Ignore the micro switch and the other bracket for my kickdown cable. You can see an ally bracket that bolts onto the corner lug of the carb which holds the cable. This also becom...

Just make sure that everything in the valve train is lubed with Graphogen or a proprietary lube before the first bedding in run.

I always use Comp Cams Hi Zinc lube additive in all my engines from new build and then add this on each oil change.

Thanks guy's really appreciate your help I've found an old spark plug will get it done Saturday. Awesome videos perry (mgbv8) Ha Ha!! I've had some fun in the old MG for sure :) Make sure that when you have fitted the stub into the old spark plug that you grind the end to a nice round dome / ball. ...

I just use a modified spark plug which has a small lenght of steel rod welded onto the end which protrudes about 20mm. I rotate the engine until no1 piston hits the TDC tool and then mark the crank pulley. I then rotate in the opposite direction until no1 piston hits the TDC tool and mark the pulle...

But that title does have the word Colon in it ??

Hello again all With the show looming I did my absolute best to get the filter housing sorted and fitted to the carb. After getting the glassing done it was a case of sanding back and doing a little more profile work to get things looking good. Following that it was out with the acid etch primer an...

Because the crank has a component of the piston mass considered to rotate with it ie acting on the crank pin, as well as the 'bottom half' of the conrod. The calculation is 100% of rotating mass(big rod ends and rod bearings)+ 50% of reciprocating mass(pistons,pins,locks and rod small end) per cyli...

That's not correct. Will the crank balance be affected - yes it will, when manufactured the crank was balanced taking a nominal piston mass into account. Does it NEED to be re-balanced. Not necessarily, a few grams of valve relief probably won't be noticeable but if you were building a race engine ...

"" Will I need crank rebalancing too ""

The crank balance will not be affected by having the pistons altered. What you need to do is make sure that after pocketing the pistons that they all get weight matched.

Thanks all. From these replies seems like 5,500 is a good red line to use and target gear changes 5000 to 5250. I am hoping to get the car dyno'd in the near future, will hopefully shed some light on the truths of the 'performance' upgrades. You would be better off getting the car on the rollers so...

When I did my last low compression RV8 build for boost + nitrous I bought a set of Omega Forged pistons with a lower compression height for my 3.9 block. This not only saw my pistons 7mm down the bores at TDC to give me a 7.5:1 CR. It also gave me a bigger chamber size to fit more charge into. The r...

Well done Del
