The car:
1966 Mustang
The weight: about 2800 with me in it
The drivetrain:
331 stroker 9.5:1 compression
RPM Intake
Speed Demon 650 carb
Trickflow stage 2 Hydraulic Roller Camshaft
Trickflow O-ringed heads - not ported
2600rpm stall converter
Built C4 with a Reverse Manual Valve body
3.55 posi rear end
125 shot of Nitrous
My original set up was almost the same as above except I had some killer ported heads, a much bigger camshaft, a vic jr intake, and no 125 shot.
With the original combo I was going to use a 1 3/4" primary header. Now, I have been trying to sell those headers to get something a little smaller. HOWEVER, now that I am going to run a 125 shot and I will probably port - match my intake and heads (both intake and exhaust sides, do youo think the 1 3/4" primary headers will be ok or should I still downgrade to a 1 5/8"? I would REALLY like to keep the big tubes if possible. The engine will spin to about 6500 rpms. Car is used as a weekend cruise, a little bit of track time.
Suggestions?
