Stock W/C T-5 + 350 TPI
I'm wanting to pull my 305 TBI and swap it for a 350 TPI (300-325 hp). Wondering if the World Class will hold up, I don't plan on being too rough with it but I know they don't have the best reputation..

Re: Stock W/C T-5 + 350 TPI
my carbed 350 has about 350 hp and i have a rebuilt T5 WC behind it. Its held up fine now for 15000 miles, about 1.5 years of daily driving. It depends on how much your car weighs. More weight will be more strain on the drivetrain. Im at about 3000 lbs without a driver

Re: Stock W/C T-5 + 350 TPI
Mine does good with a modified L98. The 3:08 gear was too high though. I have a 3:27 in it now and it's much better.

Re: Stock W/C T-5 + 350 TPI
That's some of it, but a lot of it has to do with how you drive it. In a mild DD build it's probably fine, but you're still pushing it. Doesn't take much, heh.
