This is intresting!
Could you explain this better? "the ford I build will out last three chevy motors."
If I may ask, what makes them last three times longer?
Just for a little back ground about me, the next engine I will have on my hook and engine stand will be an early 70's 390 ,,,,, but I run a CSB 305 in my 73 14.000# gvw service van,,,,,, I run 16% grades at 11,000' MSL routinely.
You bring up a good point, I am going off my experience and
admit it may be different for others! I have run with the best
both had to offer in the early days and fords held up longer
for me. The 302,chevy,the 348 chevy tripower and the 409
are good ones for chevy! The 390 you have on your stand
is a great choice where torque is a must and I am sure you
will enjoy it. It will cost more to build, the main problem with
early fords were their intakes, a good aluminum intake and
a little head work ,and good carborater or injection system
will unleash hidden potential. The 390 belongs to the group
of legendary FE engines such as 427,428cj $scj and are in
a league all their own for building horses! I know you wanted
more out of this post in explaining the 3 times as long but,
even though there are tricks, like porting the drain back holes
in the heads so oil flows better back to the engine and adding
oil coolers, they can be done on both! How many do these
tricks to make that engine humm?
