I was thinking about puttin some 4k springs on and i was wondering how man rpms i can turn suppose to the stock ones??

 

stock the fuel quits at 2200 the 3gsk stops at 2800 and the 4gsk stops at 3800. and id reckon a 3 revs to 3 and a 4 revs to 4 correct me if wrong

 

you can get over 4000rpm with a 4k kit but if u dont have 60 pound valve springs bc you will float your stock valves at 3200rpm and if you are on a stock trans you need to work on that before u do anything else i learned the hard way the i also seen in your sig u said no fuel plate u need to put that back in the truck bc u actually lose power by taking it out u need to grind the foot off of it and slide it back but while u do this push the throttle and in the pump you will see a foot come out if that foot misses the plate u slid to far make it ti where it just hits it but not miss it

 

You don't always lose power.

 

O.K this is probably a stupid question but what happens if you float your valves?

 

the piston will hit the exhaust valves

 

OK I better only go 3k i don't want to mess with putting new springs in.

 

if u ever plan on alot of boost down the road go ahead and get the valves and still do a 4gsk
