Hi:

I want to know wich one is the ebst big bore kit for the LTZ400 of these 4:

-Yoshimura 450
-Trinity racing 440
-CT racing 453
-Mickey Dunlap 500


Plz answer me anyone, wich one is better. Also, with the best of this 4 can I smoke a Predator?

 

TC racing
I forget the exact amount of cc's. Go look at
www.tcracingengines.com
TC the original Z motor builder

 

I think they are all good. And in my opinion the way mods wake up the Z I think they will all put the predator away

 

id got with the trinity for a couple of reasons.

first it puts down about 50hp with the whole kit ($1900)
and since it is a 440 you can race in the lower classes of the gncc and gnc. the none super moded ones.

on the question of will it beat a pred id say hellz yea.

the z is torquer then the pred to begin with so it beats it in accel. i think the pred has 43hp at the wheels but i might be wrong that is 13 more than a stock z yet it has a hard time beating the z in a drag race so with 7hp over the pred the z will run it over.

thats my 10cents
