I just scored a 4 bolt main 5.7 liter long block. I seems to have 2.02 heads...
Most likely a 2002 mfg engine. Out of a truck. I'm trying to figure out what exactly it is and it's specs so I can order special treats for her insides.... I will check this string daily... Pic attached. All question will be answered and apreciated. Muchas gracias!!

Roger, you can get the # off the block, call a Chevrolet dealer, the parts dept, will be able to look up the specs on the motor, the year, what it came out of.
The thing about truck motors, if it's a 4 bolt main it probally has a cast crank, and the 2 bolt main truck motors had a steel crank. And if it's an original truck motor, the heads arn't 202's, unless there not original, or it's not out of a truck. The parts dept will clear it all up for you. I couldn't tell much by the attached pic (IMG:http://www.914world.com/bbs2/html/emoticons/w00t.gif) |

Here is a list of all of the Chevrolet casting numbers. You can figure out what you have with these.

Thanks so much guys.
I looked it up and it apparently came from way back and was used on early and late models. Non Vortec obviously. The '02 applicatin was for 1 ton cargo vans. 1.94" intakes... The 2.02" measurement was in the dark. =-) Oh well, I guess I'll go the mid range cam, low rise split plentum intake, 650cfm mechanical secondary, headers route. Anyone got an extra Mallory dual point? (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) |
