One simple question

[Mearl]

I've got a 409 and a 348 both in 65 Chevy trucks, a 60 and an 80 series.

We rebuilt and modified one while I lived in Va.Fuel line size was 3/8ths.This thing held 15 qts. of oil[stock pan and filter],and weighed 1450 lbs.Most of the v6's weighed right at 750.Lotsa parts from Thunder V12.

I've seen a few 60-66 chevy/GMC pickups online that they've done the jimmy v-12(twin six)swap they had to stretch the frame and front fenders,and would smoke any tires you could put on it.

While the GMC's weren't W's,they did range from 305 cu.ins.all the way up to 478 cu.ins.

I guess that makes the 348-409 the minis doesn't it.I think GMC also made a v8 version of the engine still 60 degree and I think over 600 cubes.I think that the larger versions of those engines were to compete with ford superduty V-8's or vice versa.

My tow truck was a GMC V6, man did that thing have torque. I won 10 dollars with it, it idled up my driveway including a small trailer and a 56 Chevy. Driveway was uphill!

my 409 came out of a 1964 chris craft boat with reverse rotation.

Did your marine 409 appear to be more like a truck 409 or pass.car 409?Chris Craft seemed to lean more towards industrial/truck motors for their boats.
