I've never ran 5k's but from what I have read some of the 5k kits do not drive well. They are made mainly for competition use, now I'm not saying you can't drive a pump with 5k's on the street I just don't think its what your gonna want.

yes I really do if everything works out I will have 5k's in the truck by next pulling season

 

I would advise to stick with the 4k GSK. I'm running DDPs Comp GSK which is a 5k and I've had to replace my pushrods and camshaft right away. I'm sure as time goes, I'll be replacing more. As for pulling and drag racing, its got a really good top end especially when the second turbo lights up...

 

yeah youre right. ill stick with the 4ks. someone oline said they got one for $80 but the only onees i found were $225.00. anyone know a place to get ceaper ones?

 

talk to tony at mighty diesel his name on here is deisel pap or some thin like that. just got my 4k kit in the mail. got it for 80 bucks but hurry bc the prices will be goin up 1-877-354-7008

 

do you know when the prices are gonna go up?

 

dont no pm him deisel pap

 

should i increase timing if i get a gsk kit and have my plate cut to 100 and 1/3 forward?

 

increase time and it will hel lower egt and mpg just hareder cold starts

 

Better get valve springs if you run the 4ks and I'm serious find a kit that comes with them if you can I say go with pdrs kit but get what you want just put the damn vavle springs in or kiss the motor goodbye when you take it to 4 and float a valve

 

tony could get you a whole set of 60lb springs (12) not the cheap ones for like 130 so like 210 the whole kit
