340 Cam Kits which ones work with a stock block

Excellent post Wyrm.

Springs. To add a note to it, all valve spring are not created the same. Height, width, diameter on the inside, outside, installed height, bind distance, etc.... Sometimes it requires some work where the spring sits on the inside requiring the use of a cutter.

That would require the head to be removed. Goose your spring wisely. Look closely.

If you do t know the converters stall, I will make an error on the side of caution and suggest a smaller cam that will work with what could be considered a low stall stock converter. Hence, the [email protected] duration.

In the far past, old tyme member Mike Beck ran low 12’s in a race only Duster with a Crane cam. A split duration @ 216/228-.454/.480-112. In, IIRC, a 360.

I have been long a manual trans 4spd guy. I understand where your at. I took my problem (with advice from long time friends advice) to a local shop (ProTorque High Performance Drag Racing Torque Converters) and told them everything they needed to know except having a Dyno sheet. Which they chuckled and told me it was OK. They said, “We got your back.” They modified the stock converter to suite. Now rated to 650hp.
