Chevy 427 BB
I came across an ad for a used Chevy big block 427 engine that ran when it was pulled. Does anyone know how to tell the difference between a "Truck" motor and the "Passenger" motor. I'm hoping that its a passenger car motor but I'm not sure of how to tell the difference between the two. Any ideas on prices.
Thanks, Josh

best way is to get the vin, also measure the shaft of the distrubutor shaft length, it will be longer on a tall deck motor as opposed to a regular engine

Depending on the year, it might have a dual thermostat if it's a tall deck. Two thermostats under one waterneck.

There are two blocks....and I would definitely get the numbers and run against mortec...they do show 366 and 427 tall deck wich is 10.2".
Good luck...let us know what you find.

I have a question that may make figuring it out real easy.
Are the distributors interchaingable between a small block and a big block? I think i read that they are, but I want verification from you guys. If they do interchainge, then grab an extra one and see if it'll fit. (the tall deck is...well, taller.) |

Yes. small block and short deck big blocks can share a distributor. Only possible differences would be springs.

I got the #'s printed out from MORTEC that list both the tall decks & the short decks. I'm hoping that when I see the block numbers it'll be a short deck.
Hey miket, thanks for the link to the sight. Interesting to know that the industry is starting to build Hi performance items for the higher production number tall deck blocks. Quote from "HOTRODDERS BULLETIN BOARD" Quote:

![]() THE MAIN DIFFERENCE BETWEEN A REGULAR CAR BBC & A TALL DECK TRUCK MOTOR IS THE DECK HEIGHT. FROM THE CENTER LINE OF THE CRANK TO THE DECK IS 9.8" ON A STANDARD 427 , AS COMPARED TO 10.2" ON A 366 OR 427 TRUCK MOTOR (TALL DECK). IT'S EASY ENOUGH TO TAKE A SCALE, RULER OR MEASURING TAPE & MEASURE IT. ![]() ![]()

Well..... I was hoping. It's a truck block. The guy pulled it out of a 74' Heavy duty potato truck. Oh well.
Thanks for all of the input guys, Josh
