318 La with 360 heads

Speaking of 302’s......
The hottest 302 Ford I ever tested had CNC ported Canfield heads that flowed just over 300, Victor manifold, some tricked up carb, 1-3/4 headers, 13:1cr, and a .667 lift UD roller cam.
That motor didn’t seem like it was minding the 8200rpm pulls at all.
It didn’t quite break 500hp.
It was 1.61hp/ci, which is very good for the stuff we usually see from single carb stuff.
Mid-10’s in a small tire fox body with a Jerico.

It had more flow, more cr, more lift, roller vs flat tappet, able to peak at a much higher rpm....... but......60hp less than the generic 416.

Edit..... The 302 testing happened years and years ago, and as I was thinking about it I had some of my facts mixed up.
When it made the 495hp it had some ported Ford J302 heads on it.
When it came back the second time it had the CNC ported Canfields on it, and it made about 30hp more with those..... 525-ish. That’s likely the best single carb hp/ci motor I’ve tested.......1.71hp/ci.
He bought those heads used, and I flowed them before he put them on. They made great power on that motor but shortly after he got the car going with them, it started using water and slowed right down.
They had porosity in a few runners, and the valve seats had started moving around.

Not pertinent to the thread...... I get that.
