400 ex big bore

[416exfreak]

to u guys and gals with big bored 400's, i need some help,i need to know who makes a reliable strong performing 440 or 465 big bore kit, and should i send the motor to trinity or sparks or can i let a local engine builder(hes a professional, he built a winning IHRA top fuel alchohol motor)do it. i was actually thinking buy the kit from trinity or L.A. Sleeve or possibly 4-stroke tech, i need some help please :confused:

No help on the engine builders, but the more that you build it the less reliable that it will be. Also, make sure that they put in the larger studs. If not, you will be blowing head gaskets all of the time. Best of luck.

4-stroke tech is the most relible and probly the cheepest
