I definitely would like to go OD. Which tranny do you suggest for this application? EFI swap would be a for sure thing. What do you mean by "matching the cam" to the cars specs? I have asked him for the TC and cam spec.
Speed cost money, How fast do you want to go? I started on my '68 A-Body about 20 years ago. First upgrade was big bolt pattern with disc brakes all around. Then US Cartool's chassis stiffening kit. After 10+ years of running a Slant 6.
Then I woke up one day and pulled it out. I replaced it with a re-cammed, junkyard EFI'd 5.9 Magnum bolted to a 727. It wasn't long before I upgraded to a 500 hp 408 Magnum bolted to a 2004R with a Reid Bellhousing.
Now that motor is out and I'm replacing it with an 820 flywheel hp 408 Magnum based motor with Edy CNC'd heads, and a Holley Terminator Max controller with a Stage 2, re-geared 4L60 from Performabuilt Transmissions.
It simply as addicting as it ever has been. Captain Kirk explained it best when he told Scotty, "I've got to have more power!"
