The V8 Owners Forum -

Thanks, but I'm pretty sure the block is sound and it only has 60k on it so it's pretty clean inside. I wasn't planning to do a rebuild so I don't think it's worth it to tear it apart just to have it ultrasonically tested. I just figured it would be nice to know the block grade for piece of mind.

I have a Rover 4.6 block from 1997 that I have been planning to use for an MG V8 conversion. I have removed the valley gasket and there is no sign of any wall thickness numbers or paint dabs anywhere on the valley wall. In "How to Power Tune Rover V8 Engines" it says that before the factor...

I remember TVRLeigh posted a thread about a pretty simple method of mounting a trigger wheel on a serpentine balancer.

I think this is the thread.

Scott, I used to have a link to a very good photo of a SD1 flywheel modified to accept a GEMS reluctor ring, but the link does not seem to work anymore. The original thread where I posted it is here http://www.v8forum.co.uk/forum/viewtopic.php?t=2596&highlight= The link was http://www.mgbv8.co.u...

Using an edge graduated ruler, I measure 5 inches from the block face to the front edge of the crankshaft pully. Maybe 5 and 1/32. http://i714.photobucket.com/albums/ww150/MDTine/DSC02301.jpg http://i714.photobucket.com/albums/ww150/MDTine/DSC02303.jpg http://i714.photobucket.com/albums/ww150/MDTine...

The front cover on my GEMS 4.6 measures just 5 inches from the block face to the front of the crank pulley.
I have a photo that I'll post if someone can tell me how.

Did you have to re-balance the harmonic balancer after you mounted the trigger wheel, and if so how did you balance it?

Scott, From my understanding the GEMS engine runs a true sequential fuel injection system which requires the cam sensor to time the injection pulses for each cylinder, unlike the older Hot Wire systems which use batch fired injectors. Unless you are going to switch to a carbureted intake or an older...

There is a great guy here in the US who has just introduced a 4 link kit for the MGB (not affiliated). They have been testing it for quite a while and it’s supposed to be pretty bullet proof and capable of handling the 400+ lb/ft of torque from the big Ford and Chevy engines. At $1103 US it’s pricy ...

I just joined the forum so I could post a reply to this thread. I have been thinking of the same modification for my MGB project and found the following link which shows some photos of the modifications necessary to fit the GEMS trigger wheel to a manual SD1 flywheel. You may be able to get more spe...
