This makes all kind of sense to me. Bigger valves should equal more air and fuel in and out of engine. Now force more of both in with "the hairdryer" and more power. The price of valves are also 25% less than a v8 8)
Oh, similar topic. 340 valve springs? I read that stock 340 valves springs were a safe upgrade. Have you read anything different? Rockauto has them really inexpensive unless you think it wise to go with a name brand speed part. This is not necessarily a budget build but if I don't need a name brand part I might as well spend the cash somewhere else on the car.
We ran 340 valve springs, plus a pretty weak inner spring, but were looking at to possibility of some serious boost (the boost tries to open the intake valve,) and some 1.6:1 rocker arms and learned that with the 1.6:1 rockers, we might be getting into coil-bind with the 340 springs, so we replaced them with some Cranes (can't remember the part number, but 805Moparkid recommended them, so he probably knows). But, for your application, stock 340 springs should work fine. No need to buy some high-dollar aftermarket spring.
As for the porting and pocketing work...I am up for that as well. Bought an air compressor last summer and the neighbors have not heard me make a lot of noise with it yet :cheers:
That's great news!
If I pull the head to do this I will be able to see if this engine was ever rebuilt. The car seems in pretty original condition. Stripped basic model that the seller picked up for a song and cleaned up and sold to me. I doubt it has been rebuilt but I do have a spare engine in case I go crazy next summer and want to do more. It is also not my daily driver so I don't need to have it put together on a Sunday to drive to work on Monday.
