The V8 Owners Forum -

Cheers Ramon.

I was thinking of draining the Redline, flushing and trying your suggestion as even when the oil is warm the change is poor.

I would save the Redline and put it back in if needed.

The box has only done 500 miles since the rebuild and new oil.

Dave

Thanks Gents

One thought though. after 500 miles should the oil be like new?

I have a LT77 that has only done about 5000 miles.

She broke last year and went back to the builder for a check over. All was found OK. Since then I have only done about 500 miles.

I use Redline MTL (not Cheap) but she is a real pain when cold. When warm the gearchange is OK.

Any suggestions ...

I would go for the two relays Ian.

That would mean if one fan has a problem the other will still work.

Hi Perry

Do you think your mate has a flow restriction problem that would hold the engine back?

I guess the best thing is to do the head changes and to test it with original filter setup then just try it with the filter cover off!

Dave

I have the Webber 500 carb with a Mallory dizzy with the Petronix electronic ignition and high volt coil. I have a std cam, with a JWR Dual Plane manifold.

I have 9.75 pistons and have had the heads skimmed so I can use comp gaskets with no loss of ratio. At the same time I had the valves re-cut ...

Afraid not. I have had to jack the engine up slightly to clear the Power Steering rack.

I recon I will give the top filter a try and see what happens.

Kevin

I have just looked into this. You are completely right!!!

A MGC bonnet is £300+ :roll:

I have removed the air filter and found that the air after entering through the 2" high filter has to squeeze through a 1/2" gap before turning down into the carb. This must be a real restriction.
I will ...

It looks now if I want to get any improvement at the top end I will have to add the cost of an MGC bonnet to the price now.

I have started down that route already, with recommendations from yourself and others I have fitted a filter on one rocker and a flame trap and PCV valve into the PCV port on the Webber. It seems to be running fine.

One of the problems is I have a special Filter cover so all I could do is ...

Its 3.5 with MGOC ceramic coated block huggers and a twin system.

Perry tuned her up for me and she runs fine but I would like to stop the start-up smoke and get her to breath a bit better.

I plan on porting the head and fitting the later valve stem seals (modding guides) and if recommended ...

Not too heavy, MGB + LT77 + skinny wife.

Would the cam upgrade be worth it?

Cheers Kevin

Hi Kevin

When you say bog standard do you mean they are not SD1 heads?

30 BHP is exactly what I want. It would bring me up to 200 which is as far as I want to go. Would a change of cam (+ followers) give even more power with out losing smooth tickover and give oomph from low revs?

Dave

I am trying to roughly work out if it is feasible to upgrade my heads to give more power.

After talking to Perry I believe the most cost effective way to give a power increase is fit a better cam with porting the heads.

Is it possible to tell if I have a large valve head from a photo as at the ...
