Trinity 420 Big Bore.

Hey guys,

I was wondering if the Trinity 420 Big Bore kit was any good. I believe that it comes with pistons, sleeves, crank, pins, bearrings, and gaskets. I think that where asking around 799.99.

Personally, I wouldn't get the Trinity 420BB. I raced one last year with my stock 350, CPI's, and degree key, and beat him in a 200ft drag. If you're wanting to spend about $800, I feel like you'd be happier with a good port job, and an aftermarket head.

I've seen 420s that run and some that don't. It depends on how well they are tuned. I am impressed with the way that my 420 runs, but it can't show its full potential draggin' because I don't run a longer swingarm. As a matter of fact, I run a completely stock chassis. Mine is a Trinity Stage III, 33 PWK's, and I've run 4.8's in 300ft (stock tranny also). I think that is pretty quick considering what it is.

 

In a 200ft drag, someone without as much power can beat you if they get off the line a lot better. Just like a turbo DS. Awesome power but gets beat because he can't keep the front end down. Besides, most drags run well in excess of 200ft.

 

I guess what I'm saying is that the 420s can run. But expect to put a longer swingarm on it, otherwise someone with a lengthened modified 350 can beat you.

Also, if you do a 420 kit, i think you need to also spend some more to give it a good port job to realize its potential. A 420 without port work will have trouble with ported 350s. But if you have a 420 properly ported, then you should be faster than a 350 ported the same.
