The 396-cubic-inch (6.5 L) V8 was introduced in the 1965 Corvette as the L78 option and in the Z16 Chevelle. It had a bore of 4.094 in (104.0 mm) and a stroke of 3.76 in (96 mm), and produced 375 hp (280 kW) and 415 lb·ft (563 N·m). This version of the 396 was equipped with four bolt main bearing caps and was very comfortable with being operated in the upper 6000 rpm range.
Introduced in 1970, the 402-cubic-inch (6.6 L) was a 396-cubic-inch bored out by 0.030 in (0.76 mm). Despite the fact that it was 6 cubic inches (98 cc) larger, Chevy continued marketing it under the popular "396" label in the smaller cars while at the same time labeling it "Turbo-Jet 400" in the full-size cars.   identification number>>>3955272   1969   396/402   265 to 375 hp  2&4 bolt   identification number>>>3999290   1972   402 240hp 2 bolt

I had a 69' 396 out of a GMC truck.  I did a mild build with performer cam & intake and a 750 Holley.  I owned it for 8 years and never had to pull a valve cover, made great power.  I wish i still had it!
