COME have been around for years so they should be well sorted.

Here's the product page. What else would you need? ECU/dyno tune, injectors, fuel pump, cam?

Thanks Sambo, just thinking out a loud
Not too sure if over heating issues may occur,i think a phone call to Come Racing will sort me out.
Thanks again Paul

Would it not be cheaper and more reliable in the long run to just sell the L76 and buy an LS7? Then you would have everything designed to work with the motor.

Texas Speed do a complete 427 stroker short block for $4699.

With the good exchange rate I'd be going that way and bolting my heads and accessories to it.

If you're willing to buy from the States, I can help you with a stroker kit, short block, or complete engine.

Thanks Brent in a little worried about over heating with the kit.
Is this a issue ?
and does the block require machining ?
Thanks Paul

No issues with overheating as long as you have a good water pump and radiator. I have lots of 400-500 ci engines running around and they all run as cool as cucumbers with the right components to support the engine.

As with all new rotating assembles, I would recommend that the block be machined to make sure you start off with a good solid foundation. This includes boring/honing to fit the pistons, align honing the mains, square decking the block, etc. All of this adds to the quality and detail of the build.

A lot of the 427 builds use an aftermarket block so that you can use a 4.125" bore and a 4.000" stroke. In that case, there should be no clearancing needed (although you always check). You can also get around 427 ci with a factory block and a 4.125-4.250" crankshaft. In this case, you will need to mock up the rotating assembly, see if the rods touch anywhere, and then clearance as needed.
