apparently you are right, i thought the 4cylinders had there own pattern. the 4l60 would need beefed up as well to handle a turbo


GM metric pattern
GM 60deg V6 bellhousing.JPG

Also called the GM small corporate pattern and the S10 pattern

This pattern has a distinctive odd-sided hexagonal shape. Rear wheel drive applications have the starter mounted on the right side of the block (when viewed from the flywheel) and on the opposite side of the block than front wheel drive. The 2.2l S10/Sonoma had the starter located in the same position as front wheel drive cars. A rear wheel drive bellhousing is displayed at right.

Hey Mike, could hear the whine too!

This forum is too funny. Thanks for all the help "gentlemen". Didn't mean to call you boys, and no, not whining, just tired of everyone on here saying " do this...it'* easier"....remember, stand out from the crowd, make more power, and their jaws will drop. Who hasn't seen a SBC in a *-10? A Super3.8 in any car...but a 3.4DOHC turbo in something other than a W-Body? Well, I'll get some hate mail for my comments, that'* fine. Just not here for your "belly button" opinions. I can get that from W-Body.org! Finished with gmforum.com...no real techs out there, just shade-tree mechanics. Thanks though, to 75Racer, he sounds like he'* open minded, nice to have 1 on your side!

It seems most other forums have left a bad taste in your mouth and you appear to be a smart guy. Had you simply stated your goals in the beginning, none of this would have happened.

And quite frankly, I'm pretty tired of your side line insults to other members here. For the record, we do have a few GM Certified mechanics here. Maybe they were the smart ones quietly laughing on the floor at your 3400 idea. I dunno. Have a nice day sir.

presumably you asked the question to get opinions from people who have done engine swaps, but then you dismiss the people who tell you why you dont see 3.4 swaps and you do see v-8 swaps. if you didnt want to know why ask the question

I hear WHINE with every word typed from this dude,

As far as "making jaws drop" would be from people seeing your name "Tom" painted on the drivers door, just below the window as they drive around your wet dream of a truck, stalled in the middle of the road after you had tried to impress someone by the amount of noise it made when it backfired through the intake, catching everything on fire below where a hood could have been.

As they pass, they look at each other, "jaw dropped" and say, "did you see that POS?"
