tomcat look a my avatar that is a 540 with a 3.3 whipple and a 1180cfm dominator works good and way over 800hp yes it needs more air but to 5700 it does the job

Hi Mike:

Sorry, I forgot that you can also put a carb on top of the Whipple.

Don't get me wrong, I admire Whipple's packaging and envy their market. But all the guys running around with their standard 2.3L blower on 502s are not making anywhere near what your aluminum head 540 does with the 3.3L. If they were they would have added more than 10-15 mph. I'm not just picking on Whipple either. I have measured the same shortfalls in standard Procharger and Vortech kits; and I sell Vortech!

For a guy like Swede to get impartial information about competing kits is almost impossible. According to the ads and the loyal converts every system is THE BEST.

Gotta go, but let's talk later and really lay out the +/- of the different blowers.

Hey Mike tell them what your motor makes on the dyno.
Dont be shy!!

When I saw his dyno sheet posted on another site. Made me wanna get some of those AFR,s.

hay caveman i do like the afrs they work. tomcat would love to sometime i am always looking for a better mouse trap

I'm not sure what Mike is putting out but he was running beside me in a fun run in the velocity at 90+ this summer.

What do you guys think I would gain or lose by only changing to a roller cam while I have the engines apart? I've heard people say 20 to 30hp? Is the 741 my best bet for my 509s? The play money is low.

YES A ROLLER WOULD HELP sorry did not know the caps were on what do you turn your motors and what would you like to turn them

Tomcat,

Thanks a lot for speaking with me today and answering my questions. It was a big help!

Right now i'm turning around 5300 to 5400 about 109mph. 30" Hydromotives.

I don't have them in front of me but I think on the dyno I was about 520Ft/lbs of torque and 550hp at 5500rpm. We ran it up to 6000. Torque went down to 499 and hp was at 575.

whipple, nice torque band and more efficient than a roots.
