New in here need some advice SB 360 Cam selection

IIRC the "stock 340 cam" only came in two ways. Manual and automatic in 1968, but it doesn't really matter which at this point you have. The 340 heads had 2.02 intake valves so the your head has smaller valves than what the 340 cam was designed to be used with. I'm pretty sure my original stock,automatic 340 1968 barracuda would walk away from any Saab, but it had a little better head and was advertised at 10.5 to 1 compression. You have a better intake. If it's in the budget a set of edelbrock aluminum heads would be a great foundation to build around.
