I had them completely go through my 830 recently. I have not had time to fully flog it yet, but it runs much better than before. It pulls smooth and strong. Attention to detail was good. Lynn and Jesse seem like great people and they are priced right. I would recommend them.

 

the only way to go. jesse knows his stuff. there holley's are awsome. i had given up on holley products, until bigs.

 

I had my 950HP gone thru/blueprinted/setup by Biggs a couple of months ago. I haven't had (as of yet), a chance to bolt 'er on and see if it works yet, but if it works half as good as it looks, it's gonna kick major AZZ!
I also agree, Jesse & Lynn are great to talk to/e-mail.
(don't ask why the engine's not together yet)
