I've got a 420 right here but I'm confused as to what you want me to measure? Engine crank? What snout bolt?

center of the crank pulley to the center of the drive pulley --

OK height, I thought you were looking for length for some reason. I'm not assembled yet so let me know if I can get some other measure for you. I also have a 177 Merc SC here as well. I meassured from the front gasket surface of the intake bottom to the top of the carbs when I set mine up will that help?

I have my 177 all set up , What i'm looking at doing is finding a different , ( larger ) blower to fit in an existing configuration- ( under my hatch ) I have a brace that runs across my hatch , right about where the upper pully would be with a typical roots blower , so i'm looing at more low profile blowers -- I COULD HAVE GOTTEN A REAL NICE 250 with carbs on the boards , but i blew that one :) anyways -- I'r really interested on the dimensions of the whipple dual quad - if i can squeeze the under my hatch it would be an e ticket :)

177 is 11" from front bottom intake. 420 is 12 1/4. Height difference between the two = 1.25" Hope that helps.
I've got a just set up Merc S/C 177 with all pulleys and an 1150 Dominator if anyones interested.

Hey Lucky, you got me to thinking and I'm glad you called my attention to this. I mocked up my engine compartment on Saturday and notice how far FORWARD the blower snout sat on the new 420 I'm installing. Clears my rear seat by 3/8 of an inch, but no biggie I can allways modify that. So I get to looking down below and PANICK strikes me as I can clearly see the bottom 16 rib pulley will plant itself right into my 75 gallon gas tank! :220v: SH"+:****T I scream!!!! Well it clears up and over the tank by 3/8 " also!!! At least in my projected measuring....I HOPE!!!! See Ya.
