1967 barracuda formula s info

Definitely preserve the 273 Commando since he has a 67 Formula S. First, upgrade clutch set up to a 68 to 71 318/340 flywheel, clutch and bellhousing. For a 318 read 318willrun's posts on 318 upgrades. I would not do anything till you take the 318 apart and discover what you have, casting numbers and all. Or are you wanting to throw a camshaft, timing set, seals and run it?
