I don't want to buy a 351w sportsman block it's too expensive.
Which rpm and hp can stock block tolerate (also stock crank and rod)?because i want to use fogger system with more nos shots!!!

[V-8]

Any ideas???

I can't comment on this product specifically, but generally, this type of product is suited to drag racing aplications. Yes, it strengthens the block, but you lose some ability to maintain a stable engine temperature, depending how much product you use. You want coolant to be able to circulate through block to aid in cooling.

I would think it would cause trouble if you anticipated being stuck in traffic at times.

Ditto BMalone.

Think you'd be ahead using more standard methods of beefing up bottom end. ARP studs, Milodon 4 bolt replacement caps, stud girdle, forged crank, pistons, aftermarket rods.

But for a Cobra, you hit diminishing returns early on with added HP because the car is so light. All you're getting is more wheelspin and expensive smoke, not a faster car.

Guys around here are running 10's with mildly modified late model 302's and Vortech superchargers.

I think with an on/off NoS shot, you'd break traction and the car would flip ends on you. You'd want to come up with a system to engage NoS in several stages tho keep it just under wheelspin.
