Just use your cam, the 3.9 cam is the same, LR just moved the keyway 2
degrees to get a few extra ponies! Get an adjustable timing chain set for a
buick V-6, advance it 2 degrees, and Bob's your uncle! While you have the
timing cover off doing that, grind down the front left intake runner and
stick an HEI distributor in(off a 75-79 buick 350), you'll notice the
difference! You can buy a set of Hedman headers cheaper than just one
manifold.
Hadn't been subscribed to the coiler list for years, got this though the
V-8 list, so sorry if I repeated stuff already addressed.
