    I have heard that there is a kit out there to turn a small block into a 427. A buddy of mine told me about it, but I can't find anything on this. Anybody else hear of this? It's almost rebuild time, so I am looking at many different options before I dump a bunch of $$ into an engine.

    Yep, that would be a 400 block witha standard bore and a 4" stroke. There is a 434 which I almost built with my 400 which is a 4" stroke witha .030 overbore. Merlin also came out with their new block that can be bored out to 4.250 with a 4" stroke to make a 454ci SBC /forums/images/graemlins/thumb.gif

    Check out Bill Mitchell Hardcore Parts Source. They list a 427cid small block. /forums/images/graemlins/thumb.gif

    Request a printed catalog. Mine has more parts listed than their website. /forums/images/graemlins/thumb.gif

    www.speedomotive.com carries a bunch of different stroker kits for small blocks ranging from 406ci to 481ci - I went 415ci which could still be run on a standard block, the rest require tall deck blocks to build from.

    I hope you have more time than I do. I spent 6 months waiting for parts from speedomotive.

    I am just doing the research right now. I'll either go with a wild sbc build up (anywhere from the 383-427 range), or build a mild 350 and stuff a small blower on it. From what I can tell, a blower is actually the most dependable cost effective power you can buy. Building the engine for them is also relatively cheap (in comparison to a hi-perf. sbc). I am not sure what I am going to do yet, but I'll keep everyone posted! I need to find a cheap 4 bolt main 350 core first. That way I can take my time and build it right and not have to do it all in a mad weekend rush!
