If anyone remembers the "Cuda and the Cobra" stories I have quite a rivalry going with the Cuda. My last run against him was a 12.195 @ 111.24 mph with 1.65 60 foot. He ran a best of 12.4 @ 109.Problem is he went to track on his own last day it was open and ran a best 11.87. The track requires roll cage at faster than 11.50 so I need to get as close to that mark as I can. Basically I need 6 tenths. I added 3 " exhaust which increased 19 horse on chassis dyno before winter hit. I have also fully ported the Ebrock heads including port matching the blue thunder intake. I have increased compression 1/2 point to 11:1 added aluminum flywheel and am now picking the cam. This is a 428 engine running tri y headers, 850 dbl pumper, 4 speed 4.11 locker rear end in a 1969 Mustang. Currently I am running a hydraulic cam. Comp cams tech said unless I wanted to pull the manifold every 1500 miles for inspection stay away from solid rollers and go with solid cam. They just have not had good luck with solid rollers on the street due to spring pressures. So, I am hoping the cam choice along with the other changes will put me where I need to be.

Are your Tri-Y headers shorties? If so they are killing you. You can put all the cam you can fit in the engine and it won't do any good.------------------ Alex Denysenko Co-Administrator and Moderator NHRA/IHRA/SRA member and licensed Superstock driver MCA member# 53321 NHRA and IHRA SS/LA National Record Holder '00,'01,'02,&'03 Fleet of FoMoCo products including 88 ASC McLaren Mustang #28 Professional Manwhore The Barry of BarrysGrrl Quote #1: "I never met a magazine mechanic I liked."

They are not shorty headers. They are a tri y design though and fit above the oil pan so clearance is better than the Hooker Super comps.

Can you run open headers? Also, pick a nice cold/dry/hi barometer spring day for your t&t runs!SteveW

Well have you run it yet this year since you made all of the changes? If not, you need to do that before anything else. Also I'd try opening the headers and screw the exhuast system.I'd bet big money that those Tri-Y's are hurting you more than they are helping. Big heads, big valves, big intake, big carb. What good is getting it all in if you can't get it out? ------------------ Alex Denysenko Co-Administrator and Moderator NHRA/IHRA/SRA member and licensed Superstock driver MCA member# 53321 NHRA and IHRA SS/LA National Record Holder '00,'01,'02,&'03 Fleet of FoMoCo products including 88 ASC McLaren Mustang #28 Professional Manwhore The Barry of BarrysGrrl Quote #1: "I never met a magazine mechanic I liked."
