    Chevy Crate Engine Break-In Guide

    12681429 - GM Goodwrench 350ci Crate Engine & Packages is rated 4.7 out of 5 by 37.
    Rated 5 out of 5 by from Chevy Motor and Jegs Bought the motor for 1976 Blazer K5 Chalet. Bought with the carb , distributor , and intake and valve covers. Arrived very quickly 3 days. The install went smoothly. Fired right up and broke in the cam as described in the instructions. Have 150 miles on it now and very impressed with the product. Great power and low end torque. Changed oil at 100 miles and am ready for a road trip to go deer hunting. This is a great product and the Jegs Tech adviser answered all my questions prior to purchase. This motor has the 260 HP easily. I think its probably closer to 285 the way it is set up with the headers. The Jegs company will get my business from here on out on products they sell. Gret product great price and a great buying experience.

    Rated 5 out of 5 by from Best Buy for the Money I built 1932 Fords, I have bought 7 or 8 of the Crate 350 Chevrolet engines from Jegs. I have never had a problem with any of them. They start up and run extremely well, no oil leaks, great oil pressure. I install 3 deuce carb. intake for that hot rod look. It don't get any better than that. What a great way to put a hot rod together. You better believe that I would recommend a great deal like this to anyone.

    Rated 5 out of 5 by from Nice Bought this motor for my "old school" 40's truck. Got 400 miles on it to date. Edelbrock intake and carb, headers, HEI and TCI 350 trans. Runs good and makes good power. Just what I needed for the street. I'm not going racing ya know. It does leak a little oil at the rear seal though. I wish it was made in the USA.

    What is required to get to 260 hp? Carb,ignition, and exhaust?

    Asked by: Chip off the Old Block
    This engine would require a 4bbl carburetor like and Edelbrock 1406 and a header that would fit the chassis you are working with to make 260 HP
