the money spent on the slant to get you very little hp could be spent on the 340 or 360 (360 is cheaper and more readily available) and you would have 4X the hp as the slant.
i would like to see a small block making 800 hp that gets more attention then any built slant...
i cant go to a show without people climbing in the engine compartment... even when i was parked next to a 68 hemi charger and on the other side was an original AMC rambler(?) race car...
small blocks are so over done it just boring... besides when the chevy and import guys lose and say so i got beat to a mopar, then you can tell them its a slant six...
