402 stroking

hello,name is sam,have read a lot of post on the bb forum. i'm working on building a '71 402 for my '74 nova. block#3969854,heads#3993820.i will be running it with a t400 trans.,around 3:73's in the rear.i've already gotten a set of kb160-60 hyper. pistons.will be boring .060 over,plan on having heads ported & polished with also installing 1.88 exhaust valves.was told by kb these pistons should give me 9 to 1, 9.25 to 1 compression.also plan on going with edelbrock rpm air gap intake. i have 2 questions that i would appreciate any help with answers to.1) can i put a 4" stroke crank from a 454 in this motor and still use the new pistons i've already purchased?(any additional cubes i know is a benefit and figured should bring motor to 440 ci) 2-what howards cam and size carb would give me 450 to 500 hp? if possible. i plan on using car for hot street/sometimes strip car. any guess's or estimates this combo may give me in 1/4 mile times? thank you for any help, enjoy reading the forums and now looking forward to being involved when needed if i can help someone

you would use the KB 361 that will get 434 with a454 crank you may cut the deck of the pistons you have done it with a piston vise i done the job many times . domes need to get trimed to and re fly cut cheaper buying the pistons to fit .has for cams i could help you but sounds like you have a cam company your dealing with so call them i machine and build alot of BBC i use hyd roller s for street and sold rollers for hot street and off road . i have some roller cams and GM cast 454 cranks if needed last 402 i built and machined is 460hp and 500 tq with some work i do to the heads

hello mr mccarthy,sorry for the misunderstanding on the cam co. selection.the reason i mentioned howards is from reading some of your forum post replies and noticing how much you speak of their hyd rollers,this is what i figured to put in the 402.just wanted a recommendation of which one and the kb361 pistons i'm not to familiar with but will definitely try to find
