[J.T.]

I have a 67 GTO convertible and have lost my way on the components in my car. Over the years I have made changes that make it not enjoyable to drive now. I would like to try to keep the nice rumble at idle and roar in the exhaust under acceleration. The problem is it will chug at lower RPM cruising and cannot be taken out on the highway for any extensive period of time because of the gearing. I love how I am thrown back in the seat when I hammer through the gears or smoke the tires.
I think I would like to make more low-end torque to make this a fun car to whip around in but still be able to drive long distances. I know I am way over cammed and geared for what I want. What I have now is-
• ’72 400 block bored .030 over
• Stock crank
• Stock rods with ARP bolts
• Forged pistons
• 670 heads- 3 angle valve job, SS swirl polished valves, 7/16” studs
• Nunzi 2043N H/L cam- 308/320 deration, 500/500 lift w/1.5 rockers
• Torker II
• Holley 4150, 800cfm
• Hooker super comps into 2-1/4” exhaust
• 4:11 gears
• M20 4 speed
• 26” tall rear tire
I don’t want to just throw parts at it because that is how I got where I am. I also don’t need to reinvent the wheel. I have read so much on this here and elsewhere, my head is spinning at this point.
I have limited funds for this, but am prepared to replace the cam, gears and carb and intake if necessary.
As a starting point I am looking at
• Lunati 10510702 262/268 deration 468/489 lift
• Performer RPM intake
• 3.08 gear
What would be the winning combination?
Thanks in advance for any help.
