'69 351 heads

Florida Stang · 03-21-2002, 10:48 AM

I just bought a set of '69 351 heads that have been ported & polished. I only pay $300 for them is that a good deal? A freind told me he heard they were hard to find and they were good heads for street use. Does anyone know about '69 351 heads?

Funny, I have a set of C-9's from a 69 Torino GT on one of my work trucks, BUT! i dont know how true this is, New factory heads wont fit an older block, The engine is a 69 torino GT motor. Wonder if its strong enough to stroke and make 600 HP??? 700?

I think I'll get a baseline dyno and install the "69's then dyno again. I wounder why these heads are better than other 351 heads?

351W heads have larger ports, and the 1977 and older 351W heads also have a significantly smaller combustion chamber and larger valves.

Take care,

Chris,

What is the difference between the heads we are talking about here and a set of Edelbrock Performer's on my 69 block??

I dont think the older heads flow anywhere near what the newer ones do. The whole art of designing high flowing heads that flow consistently throught the lift range of the cam has come a long way in 33 years.

Just ran dyno baseline came up with 332 @ 4800rpm at rear wheels. Going to run it again tomorrow with "69 351 heads. Looking for a few horse power......

Your heads have bigger valves, and are 30 pounds lighter.

Take care,

Just ran my car with the 351 heads and came up with 355Hp @ 5300rpm . Not to bad 23 extra pony's. That's good for right now. Thanks for all the help you guys have gave me....Later

The '69 351W heads are nice heads. They come with slightly higher compression than the '70 heads. And have the 1.86 valves. Nice starting material. I ran these on my 351-W Zephyr Z7 that came to 10.7:1 with my combo.
Good find!
