Tim hits 15lb with the 2.5 pulley, he also has a bit more cam overlap then some so that is something to keep in mind. You can push a 1900 quite a ways.

 

I had a 2.7" on the 1900 on my 408. Made about 7-8psi and 600rwhp.

 

talked to Chris today at SDPC, im gonna go whipple i think.

 

Either way ya go you'll be a winner , having boost will make that truck run as good as it looks . Nice you also have the long tubes to compliment it.


Also since we are a little off topic on blower size/cfm, I read the new supercharged LT4 will have a 1700 TVS blower and numbers will be close to 700hp , and it spins up to 20,000 rpms .

 

Well, I sold my 67nova project today. I'll be calling Chris Negen at SDPC Monday and order my Whipple!!!! I'm freaking excited. I'm going to order the Bosch ev14 60lb injectors also. I'm going to have him order the blower with the 3.625 pulley.

 

Your gonna love it!
