I want to know if my '76 440 would stand up to about 6lbs. boost from a pair of garret turbo's that came from a couple of 3.8L Gm engines? I know the compression is down around 8.5 on the 440 and without tearing it apart it runs fine, meaning no blue or white smoke what so ever. I'm in the process of finding my compression gauge and doing a compression test anyway although I'll pull the heads off to change the head gaskets, and put a new timing chain in, for extra insurance if the bottom end will hold up.

I'm already getting plans in the works and gathering the parts to get my 727 rebuilt, and my 9.25 overhauled and a sure grip installed.

I like the tall gears in my NYer but I feel the 440 could use a little more help to step up in traffic, and the occasional 1/4 mile run just because so my cousins 5000lbs half ton with a 350 won't kick my *** so bad..

 

This should work as long as you stay conservative. The key is engine management, spark timing, boost and heat control. This is a great place to start.

Do some research first before jumping in, alot of knowledgeable people there. Check out the DIY and Junkyard stuff. My advice, be careful turbo is like nitrous or heroin, always want more.
Most important, Boost dosn't break bottom ends, Detonation Does.

 

It should, but you MUST have a near perfect tune to pull it off. You'll need a wideband AFR gauge and boost/vaccum gauge for sure. Plus you need to have it dyno tuned by a pro otherwise you'll risk ruining you engine if there is any detonation or boost spike, etc.
