302CI Engine in 1968 Z/28

[fcneg4]

2/2/2017

Two easy ones for the group:
1. Is the 302 in a 1968 Z/28 a 2-bolt main engine or a 4-bolt main engine?
2. What is the real horsepower number for that engine? Is it actually more
than 290HP?

Thanks all,

2 bolt. 350hp

67,68 were 2 bolt engines. In 69, they went with the 350 block that were 4 bolt mains. Engines put out close to 350HP..

68 had large journal crank versus small journal for 67 as I recall.

Thanks, guy! I was looking in the wrong place for messages on this topic.
Do you have L78 cars? What kind (s)? You can PM me if you like.

Thanks, Charley! I looked in the wrong place for answers to the 302 question.
You don't have a '68 RS Z/28 you plan to sell someday, do you? Is the 302 a
really strong engine?

Fred, check your PM's.

IMO yes the 302 Z-28 Engine is strong. Good bottom end and revs. Strong as far as performance, yes they are. Jerry McNeish Camaro guru runs his 67-302 Z-28 Stock Eliminator NHRA Class. 10.50 ETs all day. I believe he set a record run with that car, 10.30-ish ET.

Charlie didnt you have a Z with some sort of experimental 302 in it? What was the deal with that motor?
