Swamp Dawg:
For those of you with the standard 318 Industrials in your bombardiers what kind of performance can you squeeze out of them.  Has anybody played with cams or switched to 4 barrel carb?  Any idea what the Hp and Tq ratings this motor has.

Skenman:
Yes,
Bought a new Weiand 4bbl mani, ( don't fit, front of thermo housing hits back of water pump.)
mine a 313 industrial dodge poly head engine 1962. )
So Itraded a guy in the USA for a stock 4bbl cast intake and bolted a 650 cfm Edelbrock off road
carb on. had to make new throttle linkage hook ups, water hookups, etc..
Nite and day performance. 35% more fun. not much more gas either !!!!

1962 wide gauge.

Skenman:
I have a spec sheet for 1962
15 passenger wide, 313 v8 = 145hp.
4400lbs, width 78" 4:10 ratio
I have the 4bbl = 30 hps
and headers = 10 hp
electronic ignition..
====  be pushing 185 - 200 hp.
now that is 1962 specs.  don't know what the dyno would say ?

12 passenger narrow 251 6 cyl = 115hp
4200lbs, width 59"  4:10 ratio.

Swamp Dawg:
Thanks for that info, sounds like a real track buster!  You left the stock cam in there?

Skenman:
Same original cam, i am running an electric fuel pump, and
an aluminum gas tank 104 liter, that i have mounted outside, between the
radiator and snow cover door,, NO MORE VAPOUR LOCKING, or rusty filters.
