Small block 426 stroker with trickflow heads. How much HP.

That would be nice. My exhaust is not going to change. I dont like fenderwell headers and will keep the mufflers on it. It does get stret driven.
Race weight is 3450 lbs. My 408 went 6.57 @ 104. Never got a 1/4 mile pass.
The 426 should be a little quicker.
Hi. Can you make a list of what all you have in your 426 engine? I was going to order the huges 426 kit, but they are out of stock till the end of June. But its looking like a lot of places are out of stock. I was going to order a 408 kit. But so far everybody doesn't have anything. Oh well give me a chance to save up more money.lol
