408 stroker build

Here is what I have! !974 Australian Valiant Charger 3100lbs with driver. 410 small block , srp forged pistons,trick flow heads,victor340 manifold,800 avs carb 1 3/4 x 2 inch into 3 inch colectors with 3 inch exhaust. Cam is hyd roller237,243 with around 600 lift with 1.6 rockers, 112 lobe sep. With my old set up it made 355 rwhp and ran a best of 11.4 @119mph. The new set up now makes 425 rwhp but have not drag raced it yet as the clutch was slipping but have just put a twin plate mantic clutch in it. The car has a 5 speed TKO 600 with 3.91 diff ratio and it drives nice and smooth now and revs to 6500 easily with power all the way.I can't wait until the next drag night to see my times but the butt meter says heaps faster especeally when you hit third gear and it pulls like a train!
