what trans is in that Monte, if it is the stock 2004R or 700R4 then you wont make it through more than one launch. the combo does't sound bad. i think the carb may be alittle small but the cam isn't too small. a 800-850 i think would do better, but ive seen nasty 406's running 750's before and doing it just fine. i'm just telling you what i would do, cause carb size it bound to spark and argument on this forum and i might think about a 4000 stall so my stall speed was 500rpm higher than the begining of my cams operating range

rough ballpark est would be 575hp/515tq, you could break into the 600's it all depends on how well the heads were done
