RHS pump gas 360

This thing will accelerate much harder than you think. The TQ curve climbs very quickly. That's an indicator of acceleration.
TQ alone is not responsible for moving the car, because the engine revs so HP has to be included in acceleration. The 360 in my duster only made 460TQ. But I guarantee you the 100HP difference gets the car down the track in a much different fashion!!

This is a 100% street car that will be driven out of town on the freeway for hours at a time.

The reason I asked was my buddy is pushing me to go the cheaper route and build a stock stroke 360 using the parts I have and then have you work over the Eddie heads. He thinks the 408 would be overkill for a weekend warrior / car show cruiser type of ride.
