I was wondering if the OEM TPI system on my '85 IROC Z (305 LB9 motor) would supply enough fuel to a 383 crate motor? Would the intake manifold line up and bolt onto the 383 block?? I would appreciate any info if anyone ever performed this setup. Thank you...Joe

The intake will bolt to a 383 block. But in order to use the 383's power you would need to upgrade it. Your stock fuel system needs a bump as well. Larger injectors an adjustable fuel pressure regulator for tuning and a larger fuel pump. To help it breath headers and larger runners and a ported manifold will help also.

Oops! What I meant to ask is weather the stock manifold will line up with and bolt onto the Dart SHP Aluminum cylinder heads that come with the 383 crate motor?
