I bought a blower off of a GTP and the snout seems to be shorter than the other ones ive seen. It this just a variation of it or what? IT looks like the length will still work so im stumped. i dont want to start my top swap without knowing i have the correct S/C
 


yeah take a pic of it...you might have gotten a M62 Series 1 blower by mistake...

Does it look like...

Because for a basic top swap you need the second pic as the first one isn't compatible...and the last one is a Gen V and you'll need some adapters to get it to work.

Oh I know that...I meant on the T-Birds...didn't they use the M90 from day one back in '89? It was basically a Generation III M90 Blower with a shorter snout and smaller pulley right?

Yeah, but the inlet and outlet is totally different on the t-bird m90. Probably to accommodate for the RWD drivetrain setup.
 


Take a damned picture of it already and post it. Did you look at the pics I posted earlier in the thread? Did it look like any of those?
 
Ahhh the series 1, the cover makes it look like something from a toy car.

That's basically a copy paste from the wiki article. Its a great article to learn the history of our engines.
 
another question i have is since the supercharger uses its own belt that means i need a different crank pulley correct? is this why people just swap out the harminic balancer from an l67

Yes. If you're adding the supercharger to a 3800 that didn't previously have one you need to swap the harmonic balancer (crank pulley) for the one from an L67.
