302 casting potential?

Just giving you my REAL WORLD experience...you don't have to agree or do what I suggest. But your wrong!
I've run alot of sb mopars across our dyno, flowed alot of heads, and built a whole bunch of engines...20 years worth. But hey...what do I know...LOL!
I know it takes alot more to get 500HP or close to that than most realize or would like to admit. And I mean any small block...mopar or other.

I only suggested a 1.84 valve...that's only .060 larger than stock....030 a side difference! It also allows a better valve job to be done and with chamber work like I posted, will pickup flow and velocity and make more power everywhere in the powerband.
OK...I'm done. LOL!! Hope this helps someone out there...if not no biggie!

Dyno's are just that, not real world. I'm not here to argue one way or the other but I know for a fact that I have a 318 with 302 heads that makes over 500 HP with 1.78 and 1.60 valves, non roller and can and has run 87 pump gas and still run mid 11's for et's, 3330 lbs car.

Larger valve's don't mean more performance in every case, and from what I've learned not in this case. 30 years + racing.

Yes I agree with you it's only .030 larger but from ports and cc's this makes a big difference in flow, now mind you don't get to racing flow benches, as a head that we did and flowed great numbers actually lost power on the engine. And others that didn't flow so well made large HP gains.

I've talked to you before and discussed port shapes and flows about 5 years ago, since then I've found better shapes and how to get more flow from less. It's all a learning curve. Hey thats what were here for is to learn, and find out what works and what doesn't.
