I have a 49 Willys pickup with a Ford 302 in it. I have heard that
you can
put 351 heads on it for more power. I know this might seem off
subject but
I was wondering if anyone knows how this will afect the low end
performance.
Any thoughts...comments?
Thanks

It's been too long since I hot rodded fords to remember the details, but
here goes:
The 351 Winsor heads will bolt onto a 302. I think the 302 intake will
work, if I remember right the 351 intake will not because the block deck
height is different. There could only be two possible advantages:
1) The chamber size on the 351 heads are smaller and thus will boost
your compression. I don't think this is the case.
2) The valves and ports on the 351 heads are larger. this will help on
the upper RPM ranges but won't do diddly on the lower end, may even hurt
low end performance.
I question whether it would be worth the trouble. A torquer cam and
exhaust system mods would probably do more to boost performance than
anything.
Hope this helps
