Hi there US Slanters! I build my new slant for my GTX... and used a 390 cfm double pumper... Do you have any info on a near there main jet info for this? I´m using a 270/280 cam with 108 lobe center line, bigger valves, etc. I´m using now #58 in primaries and #60 in secondaries... secondaries seem short... (no power valve there) Here is a small video I took... http://www.youtube.com/watch?v=6gqfxrzprQw Cheers!!!!!!! |

I have close to the same jetting on mine. Comp Cam 264. I used a lighter seconary spring to get then to open a little sooner which helped with the transition. Hope this helps. |
