Cobra Make, Engine: Classic 427, I purchased it May 2005, the kit was bought in 1991. I'm not sure when it was completed! Installed GMPP Connect & Cruise 376/525 with T-56 S/M 3.55 gears about 2 years ago! 1/4 miles is with old setup!

I have been trying to get around to swapping to a TKO-600 for over a year now! I now have a built GM 700R-4 in it now. I'm not happy with the converter, @ 3000 rpm stall I may have went a bit high for the cam I have. One would think that at 62 years old I would know myself a bit better? Mild cam and carb will be enough, NOT!

I have the CRII peddle setup and a Monza V8 bellhousing. I'm planning to go with a light weight flywheel and a good single disc clutch. I'm going to pull engine and trans out and do a cam and intake swap while I'm at it! I'm going up from the Comp 280 AR (.550" lift, 280*) to the 300 AR (.575" lift, 300*) and from an RPM Air Gap to a Victor single plan intake! This is on a SBC 388, 10-1 CR with AFR 210 Race Ready Heads (2.08" x 1.60" valves), it also has a Rev Kit on it. It should pull strong to 6700-7000 but the torque is going to take a pretty big hit below 3500. SOoooo I'm going to also put a (50-75 hp) NOS TopShot on it. This should keep even my old foolish azz happy at least for a while?

I have an drum brake 8.8" with 4.11 gears and a disc brake 8.8" with I don't know what! My plan is to leave the 4.11rearend in and see what's up with the RR TKO .82 5th. If 4.11 is to much I'll go with 3.73-3.55 when I install the disc brake rear.

If anyone is running a TKO, what shifter position are you using?

This will get DONE this winter!
