I am thinking about putting in a B&M Holeshot 3000 in my 97 Z28. The company says transmission needs modifications to put it in. I was wondering what mods they are talking about. And will a aluminum flywheel effect anything in the engine.

 

Well most people in here would tell you to install a Vigilante converter. However as far as your question, the only necessary tranny mods I can think of would be a tranny cooler (B&M super cooler 24,000 GVW), and perhaps a TCI aluminum tranny pan. BTW I called Art Carr in CA and put a 2800 stall from him in my 94Z. It got me a 1.669 60' time with 3.73's. I also added a B&M shift improver kit. Bottom line is any 3000 stall converter will impress you, just some better than others. The tires in my opinion are equally as important, Fred

 

I tried to find the Vigilante converter, could you help me out as where to get one?

 

Actually, I'm partial to my ProTorque converter.

As a professional transmission builder, I can't say I know of any transmission modifications neccessary to put a stall in.

I got my Vigilante from www.tbyrnemotorsports.com/lt1catalog.html
Tom has monthly discounts, so check him out. I can't comment on the rest, but I guarantee you will not be dissapointed with a VIg. I had the 2800 SLP before. And there is no comparison between that and a 3200 Vig.
I realize I'm not comparing apples to apples. But I wish I had just got the Vig. in the first place. I've also heard good things about Yank 9" and midwest.
And I doubt that 12SCNDZ would stear you wrong. So I'd also check out the one he recommended also.

 

I'm not a professional but was full weight and on stock heads. Best MPH was also 110.49 for whatever that's worth.

 

How will the higher stall effect highway driving and cruising rpms?

 

I had the Art Carr in my old 95 Formula and it was a very good convertor. When I got my 94 Z28 I put the 2800 SLP in it and changed to the Vig. 3200 a few months back and it is my favorite of the convertors.

If I had it to do over again I would get the Vig without a doubt.

 

For beginner mind sets what was your 60'?
