Wildcat 355 was actually a 300 cubic inch with 355 lb ft torque. Is it aluminum head or steel.
In 1964, Buick replaced the 215 with an iron-block engine of very similar architecture. The new small block engine had a bore of 3.75in (95.3mm) and a stroke of 3.4in (86.4mm) for a displacement of 300-cubic-inch (4.9L). It retained the aluminum cylinder heads, intake manifold, and accessories of the 215 for a dry weight of 405lb (184kg). The 300 was offered in two-barrel form, with 9.0:1 compression, making 210hp (157kW) at 4600rpm and 310lbft (420Nm) at 2400rpm, and four-barrel form, with 11.0:1 compression, making 250hp (186kW) at 4800rpm and 355lbft (481Nm) at 3000rpm.
For 1965, the 300 switched to cast-iron heads, raising dry weight to 467lb (212kg), still quite light for a V8 engine of its era. The four-barrel option was cancelled for 1966, and the 300 was replaced entirely by the 350 in 1968.

Today's Featured Article - When Push Comes to Shove - by Dave Patterson. When I was a “kid” (still am to a deree) about two I guess, my parents couldn’t find me one day. They were horrified (we lived by the railroad), my mother thought the worst: "He’s been run over by a train, he’s gone forever!" Where did they find me? Perched up on the seat of the tractor. I’d probably plowed about 3000 acres (in my head anyway) by the time they found me. This is where my love for tractors started and has only gotten worse in my tender 50 yrs on this “green planet”. I’m par
