I will check but motor is not original .... the guy I bought truck from said its a 327 but front numbers on block don't lead to anything so I have been trying to get the back ones but motor to tight to fire wall I will pull numbers of the intake ...... please answer this ...... why would they put a 2bbl on a dump truck or school bus
Easiest way to see the casting number is a mirror and a flashlight. Angle the mirror towards the back of the head and point the flashlight at the mirror.
Easy to read that way.
...... why would they put a 2bbl on a dump truck or school bus "
Simple it's called Fuel economy! That and a natural speed governor. Those engines were designed to make low end power, no need to rev them up past 2800 rpm, thus no need for four bbl carb.
I worked on and drove some of those old busses. Sound like they are going to explode at 3200 rpm..
I've never seen a SBC that wouldn't rev any more than that. What did they differently on the truck motors? Was it all just the carb being too restrictive?
there was no such thing as a big motor in the late 50's and early sixty's
Most of the trucks had a six or a 283.. and were geared low ..
no need for a big motor ..
used the same amount of gas empty or loaded or very little difference anyway.
When you were in high gear , yuo were looking for one more gear ..
even alot of 69 -70 one tons came with the six and a bow low four speed .
Kept the motor out of a 59 three ton and it was a 283
