well i will be having the motor balanced, so is it safe to run to 65-6800 with out rev kit. and if no one has heard of it goto afr's web page.

wrong wrong wrong, the only thing right u said is about a stock motor not pulling much more than 4800 which is very true. But a 302 making power to 7k and more is very real, i see it very often. u can make a 302 rev 10k its not a problem. but you would not want to do that with a stock block. how high a motor revs has everything thing to do with the cam. you can have a balanced motor run 5k or 7k+ but it depends on the cam.

why do u want to rev ur engine to 7k?
u realise the 302 makes ZERO power past 4800 rpm's
reving to 7k will just make u slower.. its not a vtec is a v8

Ok, I see the rev kit you are talking about.. It's a different design for valve springs, but unless you are running a BIG cam and some crazy RPM's it's not needed... Just get a decent set of valve springs on whatever heads you are installing on you car and you'll be fine... My frined Kris has a 93 stock bottom end, AFR heads, Anderson Custom grind cam, and a holly systemax intake... He revs it to 6800RPMS, with 18lbs of boost through a Vortech S-Trim, and he has no problems with valve float... Just becasue a company says one of their products are a good idea, dosn't mean you should take their word for it... You should really talk with a reputable machine shop so they can point you in the right direction, but I definetly wouldn't wory about it for your application.... Good luck either way...

does he have the roller set up. that is what its for. roller lifters have a tendencie at high rpms to throw the lifter and cause valve float

RE: Where to buy a rev kit for 302
Stop reading AFR's page about valve float, roller lifters don't have big issues with it, or people wouldn't use them... Trust me, I've never seen these Rev Kits on a car, and I know of cars running all the way from 15's to 8's... I've been involved in alot of different builds, so I'm not some 15 year old trying to tell you something I know nothing about.... Good luck

RE: Where to buy a rev kit for 302
I know I'll be running my 347 to 7000. Well that's where it'll be rev limited anyway. More like 6500-6800. My cam will stop making power at 6500.
I upgraded my valve springs in my AFRs because my cam maxes out the springs that come with the 185s...
It's balanced and forged, so it'll take it.
And My friend has a 306 that revs to 7800RPM, so don't tell me that a 302 won't do any good past 7000 cause he's doing it and making power there, with a stock block.
